The Battery Charger: EVASMC Quick charger (single port) EVAGC Gang charger (six port) The blower unit draws in ambient air through the cartridges. The purified air is blown into the wearer’s hood through the breathing tube. A flow indicator is provided to check that there is an adequate volume of air available to the wearer prior to use. The system is designed to operate at a minimum air flow of approximately seven cubic feet of air per minute (210 liters per minute) in the hood under normal use on the standard speed setting, and eight and one-half cubic feet of air per minute (241 liters per minute) in the hood under normal use on the high speed setting. A feedback loop from the Mass Flow Sensor to the impellor continually monitors and adjusts the air flow to keep it constant at the design set point. The units are designed for use at temperatures from 23ºF to 129ºF (-5ºC to 55ºC). A high temperature alarm will sound at 50ºC (122ºF). The battery pack mounts in a compartment on the back of the blower. A fully charged battery pack will power the blower for approximately four to ten hours depending upon factors such as speed selected, cartridge selected, and filter/cartridge loading. The EVA Series Blower is equipped with two alarms: A 77 db continuous alarm will sound when the air flow falls below approximately 185 lpm and a 77db intermittent chirp alarm will activate to indicate that the battery has approximately 15 minutes of remaining capacity. Type C Airline Respirators CC20 Series (TC-19C-154), RT Series (TC-19C-412), GRH Series (TC-19C-412) Most of the same headpieces approved for use with the CC20, RT, and GR50 Series of supplied air respirators (SAR) are also approved for use with the EVA Series of powered air-purifying respirators. CC20, RT and GR50 Series respirators provide a high level of respiratory protection and user comfort over long work periods, in a wide variety of hazardous environments. The CC20, RT and GR50 SAR air flow control devices and other components are described in the CC20, RT and GR50 Series User Instructions. Battery Pack One fully charged battery pack will power the blower for approximately four to eight hours depending upon factors such as speed selected, cartridge selected and filer/ cartridge loading. NOTE The battery has built-in short circuit protection. In the event of a short circuit, an internal polyfuse will trip. The fuse will reset itself within 5-10 seconds allowing the battery to resume normal operation. To charge the battery pack, do the following: • Press the battery release on the pack to remove the battery from the back of the blower. (See Figure 1.) Battery release Figure 1 Figure 2 • Place battery upside down into the charging port of the battery charger. (Figure 2.) • Connect the battery charger to a 110-volt AC electrical outlet. • Charge the battery pack for approximately four hours. While the battery is charging, the light on the charger will remain red. The charger light will illuminate green when charging is complete. Table-top gang chargers EVAGC with 6 ports are also available. Diagnostic functions are available for chargers (upon special order) including access to data such as number of cycles of operation, remaining charge capacity, etc. Details for these functions are available in the EVASMC2 charger user manual (upon special order). EVA Series Powered Air-Purifying Respirator Blower Assembly User Manual WARNING DO NOT charge batteries in hazardous areas. Battery Storage Storage of Li Polymer batteries is relatively easy. Unlike Nickel batteries, they lose a very small amount of power (less than 0.5% per day) and therefore can be charged and stored ready for use. If long-term storage is required, it is best to store the battery in a cool place not below -5ºC with at least 40% charge still remaining. NOTE Discharging and re-charging the battery fully at least once every 3 months is suggested to ensure the longest possible life of the battery. Do not leave on the charger for more than 30 consecutive days. To maximize battery life, these guidelines should be followed: • Remove the battery from the blower unit when not in use. • Charge the battery before it is completely discharged. The low battery alarm indicates that the battery needs to be charged. The battery is designed with a circuit to protect the battery. It will not allow the battery to be discharged below a safe voltage for the cells, regardless of airflow, without the alarm sounding. When the battery reaches the voltage cutoff it will automatically cease operation. • Always charge the batteries at room temperature or cooler. At higher temperatures, the battery pack may not accept a full charge. If the battery pack feels hot, let it cool for 30 minutes before charging. • Do not charge battery packs in an enclosed cabinet without ventilation. Battery Fuel Gauge: Pre-Operational Inspection Prior to each work shift, perform the following Pre-Operational Inspection to ensure proper operation and to ensure that the unit is completely assembled. 1. Belt Mounted Blower Unit, Part No. EVA1 • Check that the unit is clean and undamaged. • Inspect for deterioration, physical damage and improper assembly. 2. Filter/Cartridges • Inspect the filter/cartridge for any physical damage • Check the label to ensure the filter/cartridge has not exceeded its “use-by” date. • Inspect the gasket on the filter for any physical damage. Each filter comes with a permanent gasket. • Ensure that the correct filter/cartridge is appropriate for the contaminant. • Consult the NIOSH approval label and your own in-plant safety professional if you have any questions as to the suitability and efficiency of the Air-Purifying Element. • Screw the cartridge into the port until hand-tight and the locking tab is secure. (Refer to Mounting and Replacing Filters on Blower Unit on page 5) 3. Battery Pack • Check that the battery is not damaged. • Check the Fuel Gauge to determine sufficient charge is available. Figure 4 • Place the battery pack in the battery compartment on the blower. • The battery tab should click when completely engaged. (See Figure 4) 4. H  ood with Suspension or Hard Hat, or Loose Fitting Facepiece • The hood is constructed of one of the following materials: Tychem QC, Tychem SL or Nomex (GRH). • Depending on the model of the hood selected, it may be used with either a headband suspension or a hard hat (Note: RT Series hoods are NIOSH approved without a headband suspension or a hard hat). • The loose fitting facepiece is constructed of Tychem QC and features an internal suspension. • Inspect the hood or loose fitting facepiece for any physical damage. Mounting the Breathing Tube on the Blower • Ensure that a rubber gasket is in place in the breathing tube coupler on the blower unit. • Screw one end of the breathing tube into the blower unit. (Hand tight is sufficient.) (See Figure 5) • Ensure that neither the breathing tube nor the filter is blocked. • Ensure that the ON/OFF Switch is in the OFF position. • Switch on the blower by pressing the on/ off button for 1-2 seconds confirmed by a short beep. • If the Low Battery Alarm sounds at this time, the battery needs to be recharged. See instructions on page 2 regarding properly charging the battery. Figure 5 • If the Low Flow Alarm sounds at this time, the hood, breathing tube and filter should be check for a blockage. Battery Pack / Pre-Operational Inspection EVA Battery Packs are equipped with an on-board fuel gauge to indicate the amount of remaining capacity left in the battery pack. To check the remaining capacity, simply depress the button labeled “Push” and LEDs will illuminate Figure 3 indicating the level of battery capacity remaining. When fully charged all four LEDs will illuminate green, and when 25% or less charge is available a single LED will illuminate red. NOTE 3 Checking Airflow with the Airflow Indicator (PA1AFI - sold separately) With the blower switched ON and the filters/cartridges mounted, take the free end of the breathing tube in one hand, hold it upright and place the Airflow Indicator into the end of the tube. (See Figure 6). Apply a light downward pressure to the Airflow Indicator to get a reasonable seal at the breathing tube end. Ensure that the air outlet holes in the Airflow Indicator tube are not blocked. Two hands may be used if preferred, one Figure 6 to hold the breathing tube and one to hold the Airflow Indicator. The position of the ball in the Airflow Indicator should be observed. If any part of the ball is below the PASS LINE on the Airflow Indicator, check for: • Blower malfunction. • Clogged or damaged Air-Purifying filter elements on the HE filter. See “Mounting and Replacing Cartridges on the Blower Unit” on page 7. • Low battery or battery malfunction. If the ball is completely above the PASS LINE on the Airflow Indicator, then the system is ready for use. � WARNING If the blower malfunctions during use in a hazardous area: Remain calm and LEAVE the hazardous area immediately. DO NOT use a blower that fails the flow test (air flow indicator sold separately). Use ONLY Bullard filter/cartridges which comply with and have the NIOSH approval label and which are appropriate for the contaminant. Failure to observe these warnings could result in death or serious injury.

Insert the bayonet connector of the PA20LFBT breathing tube in the hood connector and turn clockwise until it locks in place (see Figure 32). 7 Low Battery Alarm and Low Flow Alarm NOTE The EVA1 Blower unit is equipped with a Low Battery Alarm and a Low Flow Alarm. The EVA1 blower is provided with a circuit to protect the battery. It will not allow the battery to be discharged below a safe voltage for the cells, regardless of airflow, without the Alarm sounding. When the battery reaches the voltage cutoff it will automatically cease operation. When the Low Battery Alarm sounds and the filter cartridges are not clogged, the battery should be recharged to protect the battery and thereby prolong the working life of the unit. If the ball in the Airflow Indicator is BELOW or PARTLY BELOW the PASS LINE with a fully charged battery, the filter cartridges may need to be changed. The Low Battery Alarm will sound an intermittent 77 dba electronic beep indicating that there are approximately 15 minutes of remaining battery capacity. The delays between beeps will get shorter and shorter as time runs out. The Low Flow Alarm will sound a continuous 77 dba electronic beep indicating that the flow to the hood has dropped below the design specification of 185 lpm = 6.5 CFM (Note: The NIOSH minimum required flow is 170 lpm = 6 CFM). When either of these alarms sounds, the user should immediately do the following: Leave the hazard area Remove the headpiece Disconnect the breathing tube from the hood Check the airflow with the airflow indicator (see page 4).  Check the operation of the low-flow alarm by blocking the end of the breathing tube. The device will first ramp up to compensate and if correct flow cannot be achieved, the alarm will sound within 5 seconds. If the airflow indicator indicates insufficient airflow, the battery should be fully charged (see “Battery Pack” on page 2), and/or the filter/cartridge should be replaced. Doffing the Respirator Prepare to doff the blower, battery and hood in a safe, hazard-free area and do the following (in conjunction with your employer’s standard operating procedures): • Remove the hood. • Turn the blower off by holding down the on/off switch for 5 seconds.

The blower and belt assembly: EVA1 Blower Unit EVABELT1 Comfort/Decon Belt PA1AFI Air Flow Indicator 2. The battery pack (Part No. EVABAT1). One fully charged pack will power the blower for approximately four to ten hours depending upon factors such as speed, cartridge selected and cartridge loading. 3. The breathing tube, which is available in 4 options: PAHBT Powered Air Hood Breathing Tube Assembly (standard length) PAHBTXS Powered Air Hood Breathing Tube Assembly (short length) PAHBTXL Powered Air Hood Breathing Tube Assembly (long length) PAHBTBK Powered Air Hood Breathing Tube Assembly for Back Pack 4. The High Efficiency Particulate Absolute (HEPA) filter. 5. SparxLift welding helmet with Shroud. 6. The Battery Charger: EVASMC Quick charger (single port) EVASMC2 Analyzing charger EVAGC Gang charger (six port) The blower unit draws in ambient air through the filter. The purified air is blown into the wearer’s hood through the breathing tube. A flow indicator is provided to check that there is an adequate volume of air available to the wearer prior to use. The system is designed to operate at a minimum air flow of approximately seven cubic feet of air per minute (210 liters per minute) in the hood under normal use on the standard speed setting, and eight and one-half cubic feet of air per minute (241 liters per minute) in the hood under normal use on the high speed setting. A feedback loop from the Mass Flow Sensor to the impellor continually monitors and adjusts the air flow to keep it constant at the design set point. T he units are designed for use at temperatures from 23ºF to 122ºF (-5ºC to 50ºC). A high temperature alarm will sound at 50ºC (122ºF). T he battery pack mounts in a compartment on the back of the blower. A fully charged battery pack will power the blower for approximately four to ten hours depending upon factors such as speed selected, cartridge selected, and filter/cartridge loading. The EVA Series Blower is equipped with two alarms: A 77db continuous alarm will sound when the air flow falls below approximately 185 lpm and a 77db intermittent chirp alarm will activate to indicate that the battery has approximately 15 minutes of remaining capacity. Battery Pack One fully charged battery pack will power the blower for approximately four to eight hours depending upon factors such as speed selected, cartridge selected and filer/cartridge loading. NOTE  battery has built-in short circuit protection. In the event of a short The circuit, an internal polyfuse will trip. The fuse will reset itself within 5-10 seconds allowing the battery to resume normal operation. To charge the battery pack, do the following: • Press the battery release on the pack to remove the battery from the back of the blower (see Figure 1). Battery release Figure 1 Figure 2 • Place battery upside down into the charging port of the battery charger (Figure 2). • Connect the battery charger to a 110-volt AC electrical outlet. • Charge the battery pack for approximately four hours. While the battery is charging, the light on the charger will remain red. The charger light will illuminate green when charging is complete. Table-top gang chargers EVAGC with 6 ports are also available. Diagnostic functions are available for chargers (upon special order) including access to data such as number of cycles of operation, remaining charge capacity, etc. Details for these functions are available in the EVASMC2 charger user manual (upon special order). � WARNING DO NOT charge batteries in hazardous areas. Battery Storage Storage of Li Polymer batteries is relatively easy. Unlike Nickel batteries, they lose a very small amount of power (less than 0.5% per day) and therefore can be charged and stored ready for use. If long-term storage is required, it is best to store the battery in a cool place with at least 40% charge still remaining. NOTE  Discharging and re-charging the battery fully at least once every 3 months is suggested to ensure the longest possible life of the battery. Do not leave on the charger for more than 30 consecutive days. To maximize battery life, these guidelines should be followed: • Remove the battery from the blower unit when not in use. • Charge the battery before it is completely discharged. The low battery alarm indicates that the battery needs to be charged. The battery is designed with a circuit to protect the battery. It will not allow the battery to be discharged below a safe voltage for the cells, regardless of airflow, without the alarm sounding. When the battery reaches the voltage cutoff it will automatically cease operation. • Always charge the batteries at room temperature or cooler. At higher temperatures, the battery pack may not accept a full charge. If the battery pack feels hot, let it cool for 30 minutes before charging. • Do not charge battery packs in an enclosed cabinet without ventilation. Mounting the Breathing Tube on the Blower • Ensure that a rubber gasket is in place in the breathing tube coupler on the blower unit. Battery Fuel Gauge: EVA Battery Packs are equipped with an on-board fuel gauge (Figure 3) to Figure 3 indicate the amount of remaining capacity left in the battery pack. To check the remaining capacity, simply depress the button labeled “Push” and LEDs will illuminate indicating the level of battery capacity remaining. When fully charged all four LEDs will illuminate green, and when 25% or less charge is available a single LED will illuminate red. • Screw one end of the breathing tube into the blower unit - hand tight is sufficient (Figure 5). Pre-Operational Inspection • Switch on the blower by pressing the on/off button for 1-2 seconds confirmed by a short beep. Prior to each work shift, perform the following Pre-Operational Inspection to ensure proper operation and to ensure that the unit is completely assembled. 1. Belt Mounted Blower Unit, Part No. EVA1 • Check that the unit is clean and undamaged. • Inspect for deterioration, physical damage and improper assembly. 2. Filter/Cartridges • Inspect the filter/cartridge for any physical damage • Check the label to ensure the filter/cartridge has not exceeded its “use-by” date. • Inspect the gasket on the filter for any physical damage. NOTE Each filter comes with a permanent gasket. • Ensure that the correct filter/cartridge is appropriate for the contaminant. • Consult  the NIOSH approval label and your own in-plant safety professional if you have any questions as to the suitability and efficiency of the Air-Purifying Element. • Screw the cartridge into the port until hand-tight and the locking tab is secure (Refer to Mounting and Replacing Filters on Blower Unit on page 5). 3. Battery Pack • Ensure that the ON/OFF Switch is in the OFF position. Figure 5 • If the Low Battery Alarm sounds at this time, the battery needs to be recharged. See instructions on page 2 regarding properly charging the battery. • If the Low Flow Alarm sounds at this time, the hood, breathing tube and filter should be check for a blockage. Checking Airflow with the Airflow Indicator (PA1AFI) With the blower switched ON and the filters/cartridges mounted, take the free end of the breathing tube in one hand, hold it upright and place the Airflow Indicator into the end of the tube (Figure 6). Figure 6 Apply a light downward pressure to the Airflow Indicator to get a reasonable seal at the breathing tube end. Ensure that the air outlet holes in the Airflow Indicator tube are not blocked. Two hands may be used if preferred, one to hold the breathing tube and one to hold the Airflow Indicator. The position of the ball in the Airflow Indicator should be observed. If any part of the ball is below the PASS LINE on the Airflow Indicator, check for: • Blower malfunction. • Clogged or damaged Air-Purifying filter elements on the HE filter. See “Mounting and Replacing Cartridges on the Blower Unit” on page 7. • Check  that the battery is not damaged. • Low battery or battery malfunction. • Check the Fuel Gauge to determine sufficient charge is available. If the ball is completely above the PASS LINE on the Airflow Indicator, then the system is ready for use. • Place the battery pack in the battery compartment on the blower. • The battery tab should click when completely engaged (Figure 4). • Ensure that neither the breathing tube nor the filter is blocked. Figure 4 4. Helmet with Shroud (SLS1 or SLS2) • Inspect both the helmet and the shroud for any physical damage • Inspect shroud to helmet velcro attachment and ensure proper installation. • To provide a general check of system status you may wish to set the shade control to 11 and hold the helmet towards a bright incandescent light source. Under normal circumstances the filter will change from light to dark state and back to light state again as you move the helmet away. � WARNING If the blower malfunctions during use in a hazardous area: Remain calm and LEAVE the hazardous area immediately. DO NOT use a blower that fails the flow test (air flow indicator sold separately). Use ONLY Bullard filter/cartridges which comply with and have the NIOSH approval label and which are appropriate for the contaminant. Failure to observe these warnings could result in death or serious injury.

If the low battery or low flow alarm should sound, or if the user experiences any difficulty in breathing, or senses any taste or any odors from the hazard, the user should leave the hazardous area immediately. Failure to observe these warnings could result in death or serious injury. Pressing the on/off switch will change the speed to approximately 7 cfm = 198 lpm (low speed). Pressing the on/off switch additional times will toggle the unit between the two speeds. NOTE Speed change is confirmed by a short beep. Replacing the SLS1 Shroud • Remove the old shroud by pulling carefully along the velcro mating line. • To install the new shroud, start at the top of the helmet and match the loop sections of Velcro on the shroud to the corresponding hook selections of Velcro on the helmet and secure with pressure. EVA Series Powered Air-Purifying Respirator Blower Assembly User Manual (for use with SparxLift Welding Helmets) • Wrap the padded ratchet cover around the ratchet knob and secure the Velcro. • Wrap the 5/8” Velcro strips on each side of the ratchet around the headband and secure. If the airflow indicator indicates insufficient airflow, the battery should be fully charged (see “Battery Pack” on page 3), and/or the filter/cartridge should be replaced. NOTE Replacing the SLS2 APF Shroud  EVA1 blower is provided with a circuit to protect the battery. It will The not allow the battery to be discharged below a safe voltage for the cells, regardless of airflow, without the Alarm sounding. When the battery reaches the voltage cutoff it will automatically cease operation. When the Low Battery Alarm sounds and the filter cartridges are not clogged, the battery should be recharged to protect the battery and thereby prolong the working life of the unit. If the ball in the Airflow Indicator is BELOW or PARTLY BELOW the PASS LINE with a fully charged battery, the filter cartridges may need to be changed. • Remove the old shroud by pulling carefully along the velcro mating line. • To install the new shroud, start at the top of the helmet and match the loop sections of Velcro on the shroud to the corresponding hook sections of Velcro on the helmet and secure with pressure. Low Battery Alarm and Low Flow Alarm The EVA1 Blower unit is equipped with a Low Battery Alarm and a Low Flow Alarm. The Low Battery Alarm will sound an intermittent 77 dba electronic beep indicating that there are approximately 15 minutes of remaining battery capacity. The delays between beeps will get shorter and shorter as time runs out. The Low Flow Alarm will sound a continuous 77 dba electronic beep indicating that the flow to the hood has dropped below the design specification of 185 lpm = 6.5 CFM (Note: The NIOSH minimum required flow is 170 lpm = 6 CFM). When either of these alarms sounds, the user should immediately do the following: • Leave the hazard area • Remove the helmet • Disconnect the breathing tube from the hood • Check the airflow with the airflow indicator (see page 4). Doffing the Respirator Prepare to doff the blower, battery and helmet in a safe, hazard-free area and do the following (in conjunction with your employer’s standard operating procedures): • Remove the helmet. • Turn the blower off by holding down the on/off switch for 5 seconds. This is confirmed by a long beep and a shut down of the motor. • Remove the waist belt. • Disconnect the helmet from the breathing tube. • Disconnect the breathing tube from the blower. • Clean and inspect components as necessary. • Place battery on charger (as desired). •Check the operation of the low-flow alarm by blocking the end of the breathing tube. The device will first ramp up to compensate and if correct flow cannot be achieved, the alarm will sound within 5 seconds. • Place components in storage. � WARNING The use of any filter/cartridge not approved with the EVA1 blower unit may put the user at risk and could result in death or serious injury.

Changing the Front and Rear Cover Plates Control Function • Unclip and open the front cover as shown in the diagram. You will then be able to remove and replace the front cover lens as required. • Before installing the new cover lens remove the protective film from both sides. • To change the rear cover lens gently remove the cartridge from the helmet you will then be able to unclip the inner cover lens and replace it. Again, you must remove the protective film from both sides of the cover lens before installing it. Parts 1. Solar Cell Panel 2. Sensor 3. LCD Filter Plate 4. Shade Control 5. Delay Control 6. Sensitivity Control 7. RF Sensor Switch 8. Low Battery Indicator Light Sensitivity Control Where problems are encountered during welding at low amps (e.g. TIG) or there is a high level of ambient light please follow these steps. First try adjusting the sensitivity control switch. Start with the sensitivity LOW (gently turn anticlockwise until the knob stops) and adjust upwards as required. If this does not solve the problem, set the sensitivity control in the middle position and hold the helmet close to the target object and adjust the shade control completely clockwise. If the welding filter stays in the light state, leave the control set at this point. If the filter switches to the dark state, turn the shade adjustment back until the filter just switches into the light state. The filter should now be adjusted correctly. If the welding filter still does not respond appropriately, please adjust the sensitivity control again (having previously adjusted the shade control as explained above). [To achieve optimum results in very unusual circumstances you may need to perform this process again having first reset the sensitivity control to low.] RF Sensor New RF High/Low switch for even better RF sensitivity control. Switch to high for extremely low amp TIG(down to 1 amp) or when using shielded cables and welders. Switch to low when working near other welders or in areas of high RF interference to avoid false triggers and for general welding. Tig Rating RF HIGH >1 Amp RF LOW >10 Amp NOTE Always use genuine Bullard parts. Never use a welding helmet without both front and rear cover lenses installed. Changing the battery • The SparxLift uses two 3V lithium Ion batteries (CR2032) as a main power source. These batteries are user replaceable and should be replaced immediately when the battery warning light comes on and/or at least every three years. Always replace both batteries at the same time with brand new batteries. Never install previously used batteries in your helmet. • To replace the batteries slide out the battery holders from either side of the cartridge and discard the old batteries. Install the new batteries in the battery holders and slide the battery holders back into the cartridge. NOTE Always note the polarity of the batteries and install them as shown in the diagram and as marked. Batteries rely on good electrical contact to function properly and so always use clean dry hands and avoid getting dirt inside the cartridge when exchanging batteries. Changing the Inner Cover Plate on the SparxLift • From inside the helmet unclip the installed cover plate from the shell noting the locking tags on either side of the helmet (see diagram). • Remove the film from both sides of the new cover plate and then insert first one side and then the other into the relevant slots on each side of the helmet. NOTE Always check to ensure that the locking tags on each side of the helmet are properly mated with the slots in the cover plate and that the four raised guides on the helmet shell are located in the matching slots in the cover plate. Maintaining the Auto Lift assembly on the SparxLift • Assembling and disassembling the Auto Lift assembly on the SparxLift is a simple process but should be done according to the following instructions to ensure problem free operation of the helmet. • Locate the spring (10-3L) in the recess on the outside of the helmet shell ensuring that the end of the spring is hooked into the hole provided and pointing upwards. Springs are handed (R/L) and if reversed the Auto Lift mechanism will not work. • Place the spring retainer (10-2L) over the spring and ensure that the tongue of the retainer is located in the slot provided on the side of the helmet shell. • Mount the cartridge holder assembly over the spring retainer ensuring that the notches in the top of the spring retainer are nested into the matching slots on the cartridge holder assembly. • Insert the slotted bolt into the hole and over the end of the spring. • While holding the slotted bolt in place with your thumb, look inside the shell and locate the black washer over the end of the bolt which should now be visible on the inside of the shell. Note that the black washer has internal fins that mate with the end of the slotted bolt. • Insert the self tapping screw into the washer and screw it in. Avoid over-tightening. • Use a coin to tension the springs on each side by turning the head of the slotted bolts with a coin. Avoid over tensioning. Test the Auto Lift mechanism after each adjustment. Usually turning the screw a few ‘clicks’ or about 180 degrees gives perfect results.

EVA Series - Principle of Operation The EVA Series Powered Air-Purifying Respirator (PAPR) System is configured in six parts: 1. The blower and belt assembly: EVA1 Blower Unit EVABELT1 Comfort/Decon Belt PA4AFI Air Flow Indicator (sold separately) 2. The battery pack (Part No. EVABAT2). One fully charged pack will power the blower for approximately four to six hours depending upon factors such as speed, cartridge selected and cartridge loading. NOTE  The EVABAT2 is green and is not for use with Loose Fitting Hoods or Loose Fitting Face Pieces. 3. The PAFAMBT Mask breathing tube assembly (standard length) 4. The High Efficiency Particulate Absolute (HEPA) filter. 5. The Half Face Mask: The following models may be used with the EVA Series blower unit: FAM2S (Small) FAM2M (Medium) FAM2L (Large) 6. The Battery Charger: EVASMC Quick charger EVAGC Gang charger The blower unit draws in ambient air through the cartridge. The purified air is blown into the wearer’s mask through the breathing tube. A flow indicator is provided to check that there is an adequate volume of air available to the wearer prior to use. The system is designed to operate at a minimum air flow of approximately 4.5 cubic feet of air per minute (128 liters per minute) in the mask under normal use on the standard speed setting, and 5 cubic feet of air per minute (142 liters per minute) in the mask under normal use on the high speed setting. A feedback loop from the Mass Flow Sensor to the impellor continually monitors and adjusts the air flow to keep it constant at the design set point. The units are designed for use at temperatures from 10ºF to 120ºF (-12ºC to 49ºC). The battery pack mounts in a compartment on the back of the blower. A fully charged battery pack will power the blower for approximately four to six hours depending upon factors such as speed selected, cartridge selected, and filter/ cartridge loading. The EVA Series Blower is equipped with two alarms: A 77 db continuous alarm will sound when the air flow reaches approximately 115 lpm and a 77db intermittent chirp alarm will activate to indicate that the battery has approximately 15 minutes of remaining capacity. Type C Airline Respirators The FAMB Half Face Mask used with the EVA PAPR can also be configured for use in Supplied Air Configurations. Refer to the FAMB Series Supplied Air Respirator User Instructions for details. Battery Pack One fully charged battery pack will power the blower for approximately four to six hours depending upon factors such as speed selected, cartridge selected and filer/cartridge loading.

If long-term storage is required, it is best to store the battery in a cool place with at least 40% charge still remaining. NOTE  Discharging and re-charging the battery fully at least once every 3 months is suggested to ensure the longest possible life of the battery. Temperature 40% charge level (recommended storage charge level) 100% charge level (typical user charge level) 0ºC 98% after 1 year 94% after 1 year 25ºC 96% after 1 year 80% after 1 year 40ºC 85% after 1 year 65% after 1 year 60ºC 75% after 1 year 60% after 3 months To maximize battery life, these guidelines should be followed: • Remove the battery from the blower unit when not in use. • Charge the battery before it is completely discharged. The low battery alarm indicates that the battery needs to be charged. The battery is designed with a circuit to protect the battery. It will not allow the battery to be discharged below a safe voltage for the cells, regardless of airflow, without the alarm sounding. When the battery reaches the voltage cutoff it will automatically cease operation. • Always charge the batteries at room temperature or cooler. At higher temperatures, the battery pack may not accept a full charge. If the battery pack feels hot, let it cool for 30 minutes before charging. • Do not charge battery packs in an enclosed cabinet without ventilation. • Battery capacity may be checked with a diagnostic charger (special order). • Table-top gang chargers (Part No. EVAGC with 6 ports) are also available. Battery Fuel Gauge: EVA Battery Packs are equipped with an on-board fuel gauge to indicate the amount of remaining capacity left in the battery pack. To check the remaining capacity, simply depress the button Figure 3 labeled “Push” and LEDs will illuminate indicating the level of battery capacity remaining. When fully charged all four LEDs will illuminate green, and when 25% or less charge is available a single LED will illuminate red. Pre-Operational Inspection Prior to each work shift, perform the following Pre-Operational Inspection to ensure proper operation and to ensure that the unit is completely assembled. • Inspect the filter/cartridge for any physical damage • Check the label to ensure the filter/cartridge has not exceeded its “use-by” date. • Inspect the gasket on the filter for any physical damage. NOTE Each filter comes with a permanent gasket. • Ensure that the correct filter/cartridge is appropriate for the contaminant. • Consult the NIOSH approval label and your own in-plant safety professional if you have any questions as to the suitability and efficiency of the Air-Purifying Element. • Screw the cartridge into the port until handtight and the locking tab is secure. (Refer to Mounting and Replacing Filters on Blower Unit on page 5) 3. Battery Pack  NOTE The EVABAT2 is green and is not for use with Loose Fitting Hoods or Loose Fitting Figure 4 Face Pieces. • Check that the battery is not damaged. • Check the Fuel Gauge to determine sufficient charge is available. • Place the battery pack in the battery compartment on the blower. • The battery tab should click when completely engaged. (See Figure 4) 4. H  alf Face Mask and Breathing Tube • Inspect the full face mask for any physical damage, such as torn head harness straps, scratched or cracked visor and distortion of the rubber flange. • Inspect the breathing tube for tears, cracks, holes or excessive wear that might reduce the degree of protection originally provided. • Replace any damaged parts with the proper Bullard replacement part to maintain the NIOSH approval. Mounting the Breathing Tube on the Blower • Ensure that a rubber gasket is in place in the breathing tube coupler on the blower unit. • Screw one end of the breathing tube into the blower unit. (Hand tight is sufficient.) (See Figure 5). • Ensure that neither the breathing tube nor the filter is blocked. • Ensure that the ON/OFF Switch is in the OFF position. • Switch on the blower by pressing the on/off button for 1-2 seconds confirmed by a short beep. • If the Low Battery Alarm sounds at this time, the battery needs to be recharged. See instructions on page 2 regarding properly charging the battery. Figure 5 • If the Low Flow Alarm sounds after the blower reaches full speed, then the mask, breathing tube and filter should be check for a blockage. Checking Airflow with the Airflow Indicator (PA4AFI - sold separately) Mounting and Replacing Filters on the Blower Unit With the blower switched ON and the filters/ cartridges mounted, take the free end of the breathing tube in one hand, hold it upright and place the Airflow Indicator into the end of the tube. (See Figure 6). Apply a light downward pressure to the Airflow Indicator to get a reasonable seal at the breathing tube end. Ensure that the air outlet holes in the Airflow Indicator tube are not blocked. Two hands may be used if preferred, one to hold the breathing tube and one to hold the Airflow Indicator. Figure 6 The position of the ball in the Airflow Indicator should be observed. If any part of the ball is below the PASS LINE on the Airflow Indicator, check for: • Blower malfunction. • Clogged or damaged Air-Purifying filter elements on the HE filter. See “Mounting and Replacing Cartridges on the Blower Unit” on page 7. • Low battery or battery malfunction. If the ball is completely above the PASS LINE on the Airflow Indicator, then the system is ready for use. High efficiency particulate filters must be replaced when retained particles clog the filters and reduce air flow below acceptable levels, as indicated by testing with the Air Flow Indicator as described at left. � WARNING To Replace Combination Filter/Cartridge • Follow the steps above, but beware that the filter locking tab is beneath the filter rim. (see Figure 10) If the blower malfunctions during use in a hazardous area: Remain calm and LEAVE the hazardous area immediately. DO NOT use a blower that fails the flow test (air flow indicator sold separately). Use ONLY Bullard filter/cartridges which comply with and have the NIOSH approval label and which are appropriate for the contaminant. Failure to observe these warnings could result in death or serious injury.

Figure 14 Donning the Blower and Respirator Initial Donning  • Perform a negative pressure seal check: Prepare to don the blower, battery and facepiece in a safe, hazard-free area and do the following: • Ensure that the cartridge used is suitable for the contaminant in question and is compatible with the EVA Blower Unit. A) With mask on and secured, place the palm of your hand over the end of the air entry � WARNING The use of any filter/cartridge not approved with the EVA blower units may put the user at risk and could result in death or serious injury. • Check that the cartridge is properly mounted on the blower unit. • Prior to assembling the system, place the battery in the battery compartment on the back of the blower. Fit the blower and belt around the user’s waist. With the blower at the rear of the user, adjust the belt for a comfortable fit. • Remove the belt and blower. • Screw the breathing tube into the mask inlet until tight. (See Figure 15) B) Inhale until the mask collapses inward slightly (indicating there is a negative pressure). Hold your breath for five seconds. Figure 16 Figure 17 C) The  mask is deemed to be in proper position if it remained collapsed while the breath was being held and no inward leakage of outside air is detected. D) If mask doesn’t collapse or if an inward leak is detected, re-adjust mask on face and repeat above steps until the test is passed. � WARNING Persons wearing tight fitting masks, such as the FAMB series, are required by OSHA to be fit tested before initial use and at least annually thereafter. Seal checks are to be performed before each use. If you cannot attain a proper fit test and seal, try another mask size and repeat the steps outline previously. If a proper fit and seal is still not achieved do not use the respirator. Turn on the blower, and attach the breathing tube to the blower. With the air flowing into your respirator, you are now ready to enter the work area. Donning the FAMB Mask Figure 15 � Warning Do not wear the EVA half mask PAPR if facial hair is present that comes between the sealing surface of the facepiece and the face, or that interferes with valve function. Failure to follow these instructions could result in death or serious injury. • Loosen the mask’s elastic straps. • Grasp the front of the facepiece with one hand and the upper strap with the other hand. • Position the respirator on your face so that the inside portion of the facepiece is under your chin and the narrow portion of the facepiece is over your nose. Figure 18 � WARNING The mask over must be used when operating this respirator. This part protects the exhalation valve from outside interference. Failure to follow these instructions could result in death or serious injury. Final Donning: • Attach the other end of breathing tube to blower unit (if not already attached) by screwing adapters together. • Put on the belt and blower assembly and make any final adjustments to the belt as necessary. • Turn the blower on by depressing and holding the on/off switch (Figure 19) for on/off switch approximately 1 second indicated by a short beep. • Buckle the belt onto the waist (blower unit should be in the lower back of the wearer). Figure 19 • Choose speed setting (see below). • Place the mask on the head making any final adjustments to the fit as required at this time to ensure a comfortable and stable fit. � WARNING Do not enter a hazardous area until you are sure that the blower and mask are fully operational and the blower is running. The user should periodically leave the hazardous area to check the airflow through the system. If the low battery or low flow alarm should sound, or if the user experiences any difficulty in breathing, or senses any taste or any odors from the hazard, the user should leave the hazardous area immediately. Failure to observe these warnings could result in death or serious injury. Speed Selection The EVA1 Blower is equipped with the ability for the user to select one of two speeds for operation. When the unit is initially turned on and green EVABAT2 is installed, the blower will operate at approximately 5.0 cfm=142 lpm. NOTE The battery life is reduced at the higher speed. Pressing the on/off switch will change the speed to approximately 4.5 cfm = 128 lpm (low speed). Pressing the on/off switch additional times will toggle the unit between the two speeds. NOTE Speed change is confirmed by a short beep. Low Battery Alarm and Low Flow Alarm The EVA1 Blower unit is equipped with a Low Battery Alarm and a Low Flow Alarm. The Low Battery Alarm will sound an intermittent 77 dba electronic beep indicating that there are approximately 15 minutes of remaining battery capacity. The delays between beeps will get shorter and shorter as time runs out. The Low Flow Alarm will sound a continuous 77 dba electronic beep indicating that the flow to the mask has dropped to the design specification of 115 lpm = 4.0 CFM (Note: The NIOSH minimum required flow is 115 lpm=4 CFM). Low Battery Alarm and Low Flow Alarm (continued) When either of these alarms sounds, the user should immediately do the following: Leave the hazard area Remove the headpiece Disconnect the breathing tube from the mask Check the airflow with the airflow indicator (see page 4). If the airflow indicator indicates insufficient airflow, the battery should be fully charged (see “Battery Pack” on page 2), and/or the filter/cartridge should be replaced. NOTE  EVA1 blower is provided with a circuit to protect the battery. It will The not allow the battery to be discharged below a safe voltage for the cells, regardless of airflow, without the Alarm sounding. When the battery reaches the voltage cutoff it will automatically cease operation. When the Low Battery Alarm sounds and the filter cartridge is not clogged, the battery should be recharged to protect the battery and thereby prolong the working life of the unit. If the ball in the Airflow Indicator is BELOW or PARTLY BELOW the PASS LINE with a fully charged battery, the filter cartridge may need to be changed. Doffing the Respirator Prepare to doff the blower, battery and mask in a safe, hazard-free area and do the following (in conjunction with your employer’s standard operating procedures): • Remove the mask • Turn the blower off by holding down the on/off switch for 5 seconds. This is confirmed by a long beep and a shut down of the motor. • Remove the waist belt. • Disconnect the mask from the breathing tube. • Disconnect the breathing tube from the blower. • Clean and inspect components as necessary. • Place battery on charger (as desired). • Place components in storage. � WARNING The use of any filter/cartridge not approved with the EVA1 blower unit may put the user at risk and could result in death or serious injury.

Consult your local safety professional if you suspect that contaminant has entered the breathing tube. When cleaning the equipment, do the following: Ensure water does not enter cartridges. Replace wet cartridges. DO NOT use gasoline, organic-based solvents, or chlorinated degreasing fluids (such as trichloroethylene) as they will cause damage. DO NOT immerse the equipment in water or other cleaning fluid as this may cause contamination in the breathing tube and blower interior that will be difficult to remove. DO NOT store respirator in your work area or leave it unattended in a contaminated environment. Respirable contaminants can remain suspended in air for more than one hour after work activity ceases, even though you may not see them. Proper work practice requires you to wear the respirator until you are outside the contaminated area. If you set the respirator down in a contaminated environment, contaminants, dirt and dust could get into the respirator. When you put the respirator back on, you could breathe in contaminants upon reuse. Failure to observe the instructions and warnings in this manual invalidates all performance statements and approvals for this equipment and could result in death or serious injury. Mask Immerse the facepiece in warm water (about 120º F) with mild detergent or a germicidal disinfecting detergent. The respirator body and parts may be scrubbed gently with a cloth or soft brush. All foreign matter must be removed carefully from all surfaces of the exhalation valve flaps and seats. Wipe any areas still showing accumulations of foreign matter with a cloth moistened in a detergent or a solvent such as mineral spirits or naphtha, until clean. Stubborn accumulations of paints, lacquers, or enamels may be removed with a cloth containing a paint, enamel, or lacquer stripping agent. Once the dirt or paint is loosened, it may be gently rubbed or brushed off. Do not use volatile solvents for cleaning this respirator or any parts or assemblies. Strong cleaning and disinfecting agents, and many solvents, can damage the silicone rubber and plastic parts. Do not leave solvents and strong cleaning and sanitizing agents in contact with silicone rubber or plastic surfaces any longer than necessary to loosen the accumulations of dirt or contaminants. Rinse the respirator in clean, warm water (about 120º F). Shake to remove excess water, and allow to air-dry away from direct heat, sunlight or contaminants. Breathing Tube Inspect the breathing tube for tears, cracks, holes or excessive wear that might reduce the degree of protection originally provided. Be sure the quick-disconnect fitting is screwed tightly into the breathing tube so no air can escape. This respirator and all of its component parts and assemblies should be inspected for damage or excessive wear before and after each use to ensure proper functioning. Immediately remove the respirator from service and replace parts or assemblies that show any sign of failure or excessive wear that might reduce the degree of protection. If any signs of excessive wear are present, replace the breathing tube assembly immediately or remove the respirator from service. Use only complete NIOSH-approved Bullard FAMB or EVA components and replacement parts on this respirator. Refer to the parts list for correct part numbers. Blower Unit Once cartridges have reached the end of their useful life, discard in accordance with federal, state, and local guidelines, and in conformance with plant safety regulations. The respirator should be cleaned, inspected and sanitized at least weekly or more often if subjected to heavy use. Respirators used by more than one person must be cleaned, inspected and sanitized after each use. If not cleaned, contamination may cause illness or disease. Remember, the air you breathe will not be clean unless the respirator you wear is clean. Hand-sponge breathing tube with warm water and mild detergent, rinse and air-dry. Do not get water inside the breathing tube. After cleaning, once again carefully inspect breathing tube for signs of damage. Use a lint-free cloth moistened in a mild solution of soap and warm water to clean the outer surface of the equipment. Re-charge the battery pack (see instructions on page 2). Storage When the apparatus is completely clean and dry, and after inspection, place it in a clean plastic bag or air tight container.
