INTRODUCTION & UNPACKING Congratulations on your purchase of a new H.E.R.O. “EC” series airless paint sprayer. We are sure you will enjoy owning and operating your new sprayer. With H.E.R.O. airless spray equipment you will enjoy the features and benefits of this airless. You are spraying paint, not air, and the paint is driven to the painting surface in a clean, fan shaped spray which penetrates all cracks and corners. To attain these results, you must adjust the pressure as low as possible. We recommend that you become familiar with your H.E.R.O. unit. Discuss with your dealer the useful accessory items they do offer - various types of tips, extension poles for hard to reach areas, extra hose, etc. Use of accessory items is often the difference between a good job and an excellent one ! Your H.E.R.O. airless sprayer has been fully tested and carefully packaged to avoid damage. It should be carefully examined upon arrival to determine that the unit shows no signs of freight damage. If any parts are found broken or damaged, immediately contact the carrier and arrange for an inspection of the concealed damaged. Claims for damage MUST be made by the CONSIGNEE and not the shipper. The carrier accepts full responsibility for the safe delivery of merchandise upon pick-up from the shipper. The unit shipping carton contains:
EC-1000 Unitool (OPTIONAL) EC-2600 Siphon Hose Assembly (High Boy model)
EC-2560 Siphon Hose Assembly (Sled and Cart models)

SET UP Setting Up: 1. Attach siphon hose assembly to intake valve by pulling up intake elbow onto intake valve. 2. Lock clip onto intake valve by sliding clip until it is locked into its designated slot. 3. Connect prime hose to prime hose outlet making sure that it is wrench tight. 4. Connect airless hose to pump outlet making sure that it is wrench tight. 5. Connect airless gun to airless hose making sure that it is wrench tight and slide the trigger safety lock up to lock the trigger closed. 6. Remove spray tip from tip guard. This is done by twisting the tip until it aligns with the tip guard opening and then by pulling the tip out of the housing. The tip guard may have to be loosened to help remove the spray tip. By removing the tip this will make flushing out the storage solution safer and easier. 7. Place siphon tube into one gallon of thinner or flushing fluid. This will be necessary to flush storage solution from pump. If using a highly volatile solvent or paint in a metal container it is highly recommended to ground the container with a grounding wire to ground to prevent risk of static discharge. If storage solution has been flushed already with thinner, then sprayer should be flushed with water if using water base paints or flushed with correct thinner for oil base paints. Check paint manufacturer recommendations. 8. Apply packing lubricant. This will help prevent buildup of materials on the piston rod thus extending packing life. To add lubricant, insert pointed nozzle of the 3PL liquid into the slotted area in the front of the unit. Add only a small amount . This should be done each time the sprayer is used. Before each use, flush the pump with the correct thinner for the paint being used. NOTE: The unit MUST be stored with mineral spirits at all times in order to protect pump from corrosion and extend pump life.

START UP Setting Up (Continued): 1. Flip prime valve lever up to open. This is required to remove air out of the pump. 2. Turn pressure control knob counter clockwise to lowest set ting. This will cut the power off until the pressure control knob is turned clockwise to desired setting. 3. Make sure that the power switch is in the “off” position and plug the power cord into a 115V, 15 amp., grounded circuit. Note; if using an extension cord, you must use a #12/3 wire grounded cord, up to 50 feet or #10/3 wire grounded cord up to 100 feet. DO NOT EXCEED 100 FEET OF EXTENSION CORD. If distance is greater, purchase and install additional lengths of airless spray hose. 4. Flip the power switch to the “on” position. 5. Slowly turn the pressure control knob clockwise until motor runs. 6. As motor is running with the prime valve open, the bypass light will be lit to show that the unit is in prime or “bypass” mode. 7. Allow sufficient time for thinner to circulate back into the siphon container. It should be flowing at a constant rate and this may take seconds to minutes depending on the viscosity of the paint or flushing fluid. 8. Flip the prime valve lever down to its “closed” position. The unit should start to build pressure. Check to see if there are any leaks from any connections. DO NOT attempt to try to stop any leaks with your hand or with a rag. If leakage occurs, shut the power switch to the “off position immediately and flip the prime valve up to open and release any remaining pressure. Tighten and recheck connections on all fittings and repeat from step 1. If no leaks continue to step 9 on page 7.

START UP 9. The unit should shut off automatically once it reaches its set pressure. At this point keep the pressure set low, between 500 to 1000 psi. The display should now show the pressure and the spray light should now be lit. This means that the sprayer is under pressure and ready to spray. 10. Obtain an empty waste container to flush out storage solution. Unlock gun trigger and trigger into the waste container and spray until thinner and or paint is flowing out of gun. 11. The storage solution is now flushed from the sprayer and is ready for spraying. Gun safety trigger should now be locked. If unit has been flushed previously and paint is ready to spray, then proceed to step 12. If paint has not been primed though pump then repeat steps 7 and 8 on set up page and steps 1 to 12 on start up page. 12. Install spray tip into tip guard. If unsure of which spray tip to use, refer to spray tip selection chart on page 8. Please read the next following pages for the pressure adjustment, spray, maintenance, and troubleshooting instructions.
SPRAY TIP SELECTION
Hero Flip Tips are coded with three (3) numbers. To determine the fan size: 1. Double the first number (I.E. : 4 x 2 = 8” inch fan width) this is determined at approximately 12” inches away from the surface. 2. The last two (2) numbers indicate the orifice size in 1/1000 of an inch. This is very important as it controls the flow, output of the sprayer, and overall spray quality.
Owner’s Manual

EC621 / EC725
SPRAY TIP SELECTION – cont. Different materials require different sizes of tips, and different paint manufactures produce different qualities of paints. These materials will effect the overall life of the tip. It is very important to choose and monitor the right spray tip. It is advisable to obtain a spray tip recommendation from the supplier of the material to be sprayed. The following table is a general guide and will assist in selecting the optimum tip to use.

NOTE: In order to test if a tip is worn, spray a small amount of suitable material on a test surface and observe the spray pattern produced on the surface. Try to obtain an even elliptical spray pattern by first adjusting the pressure down, then gradually increasing pressure until full atomization is achieved. This should result in a crisp spray pattern with sharp edges and even concentration, see diagram below. If a satisfactory pattern is unattainable ( look for edges to be rounded with heavier concentration ), then the tip is worn and should be replaced. Other causes of poor spray fan are insufficient spray pressure and material viscosity ( may requiring thinning ).
Good Tip
Worn Tip
Uneven Spray Pattern
NOTE: Use of excessively worn tip can result in apparent poor performance of pump. ORIFICE SIZE All tips are rated by the size of the orifice or bore size. The bore size is measured in thousandths of an inch ( .017 = 17 thousandths of an inch ). The size of tip required is based on the consistency of the material to be sprayed. The thicker the paint, the larger the tip size required. Always consult the product label or ask the paint retailer for the manufacturer's recommendations with regard to proper tip sizes. FAN WIDTH Fan width or pattern width is determined by the spray tip's "fan width" classification. This size is measured in inches, and is determined when spraying 12 inches from the spray surface and the tip of the gun. Various methods of noting the fan widths are used by tip manufacturers. Ask your distributor for assistance. NOTE: Two tips having the same tip size, but different fan widths will deliver the same amount of paint over a different area (wider or narrower strip). SPRAY TIP REPLACEMENT During use, especially with Latex paint, high pressure and material abrasion will cause the orifice to grow larger. As the orifice grows larger, the fan width grows smaller. Replace tips before they become excessively worn. Worn tips waste paint, cause over spray, and decrease sprayer performance. NOTE: When using Latex paint, a spray tip will wear at the rate of one size for approximately every 100 gallons of material sprayed.

AIRLESS SPRAY PAINTING SUGGESTIONS A good airless spray application is the result of many factors. Surface preparation, which includes cleaning and degreasing, priming, material compatibility, quality finish product and correct application technique. All are important to the finished results. The key to all good applications is a good spray gun technique. Proper application techniques can easily be learned by using the following simple guidelines. If you are not familiar with the basic spray techniques we recommend that you study this portion of the manual and practice the techniques shown. Practice your technique on scrap cardboard or old newspaper until you feel confident.
FOR EXCELLENT RESULTS, READ AND PRACTICE THESE TECHNIQUES 1.

5. 6. 7.
Always strain all paint through a H.E.R.O. strainer bag. The most common reason for airless sprayer’s to malfunction is foreign matter jamming the valves or plugging the tip. Always strain the paint before putting it through the pump. Always spray at the lowest pressure setting which will provide a uniform spray fan (fig. 1). Adjust pressure control knob so that paint is completely atomized. Insufficient pressure will result in "tailing". Too much pressure will result in excess fog and over spray, excess tip wear, and increased sprayer wear and tear. Always spray at right angles to the surface being sprayed (fig. 2). Angling or arcing the nozzle toward the surface will cause uneven coverage and excessive over spray. Always hold spray gun 11-12 inches from spray surface (fig. 3). Too close and the fan width will be reduced and material will be applied too heavily which will cause the paint run or sag. Too far from the surface causes excessive over spray and light coverage (transparent). Always move the gun parallel to the surface being sprayed, at a consistent speed. This avoids uneven coverage. Always start the spray stroke before triggering the gun and release the trigger before completing the stroke (fig. 4). This avoids heavy build up of paint at either end of the spray stroke. Always lap your spray pattern by one half (fig. 5). This assures full coverage of the surface being painted.

FIG. 5 When spraying you may encounter a problem with the spray tip plugging up which will either cause the spray fan to spit, splatter, finger or just shut off completely. The most likely cause is the spray tip has partially or completely plugged up with foreign debris from the paint. To fix this problem it is recommended that: 1. The safety lock on the gun trigger should be locked to prevent any mishandling of the gun while correcting the tip plug. This is done by sliding up the lock tab which is located behind the gun trigger until it is fully engaged and the trigger can no longer be depressed as shown in fig. 6. 2. Twist the spray tip 180° degrees around as shown in fig. 7. 3. The gun should now be triggered away from the spray surface until the spray tip becomes unplugged. 4. After the spray tip has been unplugged twist the tip forward 180° degrees. 5. Slide the trigger safety lock down to release the lock to continue spraying. 6. If problem persists check the gun filter and manifold filter and clean or replace if necessary.

PRESSURE RELIEF / SHUT DOWN / CLEANING When finished spraying or switching to a different paint, the sprayer will need to be cleaned thoroughly. The following steps should help you through the pressure relief, shut down and/or cleaning process. It is very important to read these instructions as the sprayer will be under high pressure and if the pressure is not relieved correctly it can seriously harm or cause injury. 1. Push the gun safety lock up to lock trigger. This will prevent accidental pulling of the trigger when performing shut down of the sprayer. 2. Flip the power switch down to the “off” position to shut power off to the sprayer. 3. Unplug the power cord from the power source. This should removed by pulling it by the plug end and not by the cord. This will prevent the wires in the cord from stretching. 4. Turn the pressure control knob counter clockwise to the lowest setting. This will prevent the sprayer from turning on too soon when the power is switched on. 5. Obtain a separate waste container and trigger gun into the container to relieve pressure in sprayer. This can be done with or without the spray tip in place. 6. Flip the prime valve up to open and release any remaining pressure in the sprayer. 7. Place siphon hose assembly into the correct cleaning solution. If unsure of which solution to use, refer to the paint manufacturers cleaning instructions on the paint container. Hero Wonder Wash is recommended. This is a great cleaning solution to clean the pump when water based paints or stains have been used. 8. Remove spray tip from gun. This will help to speed up cleaning the hose and when sprayer is being cleaned. Continued on page 12.

EC621 / EC725
PRESSURE RELIEF / SHUT DOWN / CLEANING 9. Plug the power cord into a 115 volt, 15 amp grounded circuit. It is very important that the grounding terminal be place as this will prevent any static discharge when using hot solvents. 10. Flip the power switch up to the “on” position. 11. Slowly turn the pressure control knob clockwise until motor runs steadily. This will ensure there is enough rpm for the pump to create suction. 12. With the prime valve open and the pump working, the cleaning solution should now start flowing into the waste container. The bypass light should be lit to indicate that the sprayer is in “bypass” mode. This means that the sprayer is priming. 13. Allow enough time for the cleaning solution to flow and rinse through the pump section of the sprayer. This can take several minutes depending on paint or coating in the pump and siphon hose assembly. 14. Flip prime valve down to close once pump has had enough time for cleaning solution to rinse through. 15. Unit should now be building pressure and will shut off to its setting which is displayed on digital display. Pressure should be set low, between 500 to 1000 psi. The spray light should also be lit on the display which indicates that the sprayer is under pressure and ready to spray. 16. Unlock gun safety lock on trigger and spray into a waste container until gun and hose is thoroughly rinsed with cleaning solution. Lock gun safety lock on trigger and insert spray tip back into the tip guard, unlock safety trigger and trigger once again to clean spray tip. Once sprayer has been completely rinsed with cleaning solution, repeat steps 1 to 6 on page 11 to safely relieve pressure from sprayer . The sprayer’s filters should now be checked, cleaned or replaced if required. To check the filters on your sprayer go to page 13.

FILTER MAINTENANCE The Hero “EC” series airless sprayers are equipped with 2 stages of filtration. The first stage of filtration starts at the siphon hose, which will help prevent small to large pieces of debris that would cause damage to the pump, from entering. The second stage of filtration is an integral filter manifold. This manifold will help filter out the impurities found in the various paints and coatings. This second stage of filtration will further filter out these impurities before reaching the spray gun which will help the longevity of the spray gun and tip. Staying on top of proper filter maintenance will decrease the chance of problems with the pump, and spray gun and increase the overall longevity of your sprayer. Both filters are available from your Hero dealer. Follow steps 1 to 6 on page 11 to safely relieve pressure from sprayer before attempting to check filters.
To check or remove the siphon hose filter, unscrew the filter counter clockwise as shown in Fig. 1. The filter should be clean and be free of debris, Replace if necessary. It should be used at all times to prevent unwanted objects from entering and causing damage to the pump. To check or remove the manifold filter, unscrew the filter housing counter clockwise as shown in Fig 2 and Fig 3. Once the housing has been removed, you will find the filter screen and the filter support spring. The screen should be cleaned after every use to prevent plugging and or filter collapse. If the filter is not cleanable then it should be replaced. The standard filter size that comes with your sprayer is “60 mesh” which is good for most water and oil based coatings. For higher build paint products, the filter should be changed to a “30 mesh” filter which would allow the thicker material to more easily flow through the filter. For fine finish applications when using oil based enamels and lacquers it is recommended that the filter should be changed to a 100 mesh filter which would better filter out any small debris before reaching the spray gun and tip. These filters can be ordered through your Hero dealer. To reinstall the filter assembly, insert the support spring into the filter screen and insert it into the pump manifold. Next screw the filter housing clockwise into the pump manifold and hand tighten until snug.

REPAIR PROCEDURES The H.E.R.O. EC units were specifically designed to assist the operator in dealing with the inconvenient, time consuming, and some times technically challenging concept of equipment service and repair. The EC models offer simple, quick, easy to perform procedures for all the fluid section repair procedures. Servicing and the repair of the fluid section can be performed with one simple tool, the H.E.R.O. “UNI-TOOL™” , ( Part # EC-1000 ). The complete fluid section can be removed and replaced in about 5 minutes.
EC-1000 EC-2700
FLUID SECTION Tip the entire unit back into a vertical position. this provides greater access to the fluid section, while making repairs. 1. Complete “Pressure Relief Procedures” as described on page 4 2. Unplug power cord from electrical source. 3. Remove the siphon assembly (Ref # 1) if a sled or low-boy cart or (Ref #2) if a high boy cart from intake valve (Ref #24) by pushing the release clip (Ref # 6) over to the side and pulling the siphon assembly away from the intake valve. NOTE: Bleed hose does not need be removed while servicing, however you may find it convenient to do so. 4. Using the 1/4” Allan key of your H.E.R.O. Uni-Tool (Part # EC-1000, supplied with each unit), loosen the four manifold bolts counter clockwise 1/2 a turn as shown in Fig 3. 5.

PISTON CARTRIDGE ASSEMBLY REPAIRS – DISMANTLING The Piston Cartridge Assembly is available as a complete, pre-assembled cartridge for quick, on site, unit repairs. Items are also available individually for more economical repairs when time is not of the essence. We recommend keeping a new or previously re-build Piston Cartridge Assembly in your tool box at all times, for those urgent on the job replacements. The used or worn Piston Cartridge assemblies can then be repaired at a more convenient time.
Remove the “Piston Cartridge Assembly” as per the instructions on page 18 & 19. 1. To dismantle the piston cartridge assembly, push the piston valve body (Ref # 13), down through the cylinder (Ref # 20). This will remove all items marked Ref # 12 through 17. Note upper packings will remain in the cylinder (Ref # 20). 2. Remove upper packings from cylinder. 3. Remove piston sleeve (Ref # 12) from piston valve body (Ref #13). 4. Remove lower packings from piston valve body (Ref # 13). 5. Place piston valve body in vise or secure firmly with a 5/8’’ wrench, and use the 1/4” hex wrench side of the UNI-TOOL to remove the seat retainer (Ref # 17) from the piston valve body. 6. Remove the piston ball (Ref # 15), piston seat washer (Ref # 16).

PISTON CARTRIDGE ASSEMBLY REPAIRS – ASSEMBLY 1. 2. 3. 4.
Slide o-ring (Ref # 14) onto piston valve body (Ref # 13). Place piston valve ball (Ref # 15) into piston valve (Ref # 13). Insert piston valve washer (Ref # 16) into piston valve (Ref #13). Insert piston valve seat (Ref # 17), (bevel side facing ball) into piston valve (Ref #13). 5. Apply LocTite 271 (Red) to piston seat (Ref # 17), and screw piston seat tight using the 1/4” hex side of the UNI-TOOL. 6. Apply a small amount of grease (common automotive grease) into the “V” portion of each packing set component. Re-assembly and squeeze packings set together. Remove any excess grease (leave a small portion) from the outer perimeter. NOTE: Our testing has shown that a longer packing life is obtained when the seals are pre-lubricated in the manner described above. 7. Slide the lubricated, lower packing assembly onto piston valve (Ref #13). 8. Slide the steel washer onto piston valve. 9. Slide piston sleeve (Ref # 12) onto piston valve, with the four (4) holes closest to the lower packings. 10. Assemble the back up ring (Ref # 18) and cylinder o-ring (Ref # 19) onto cylinder. The cylinder o-rings are always placed on the inner side of the cylinder, facing each other. Back up o-rings are always on the outer side of the cylinder (far ends). 11. Slide cylinder (Ref # 20) over piston valve and lower packings. Ensure the (4) cylinder outlet holes are at the top (refer to diagram). 12. Insert upper cylinder retaining clip (Ref # 21) into cylinder (Ref # 20). NOTE: This clip will remain in the cylinder during dismantling and should not be removed. 13. Slide the lubricated, upper packing assembly (see step 7 & 8) into the cylinder until only approximately 1/8” of packings is exposed above the cylinder. 14. With piston cartridge fully assembled, move back to the unit and tighten the four (4) pump manifold bolts (Ref # 32) to 30 foot pounds as shown in Fig. 1. (Loosened in step 4 of removal instruction on page 18). 15. Insert the fully assembled piston cartridge assembly (Ref # 11) into the pump manifold (Ref # 44) as shown in Fig. 2 and thread into the con-rod (Ref # 111). Tighten to 30 foot pounds. 16. Install intake valve (Ref # 24) with the 3/8” hex key side of the UNI-TOOL as shown in Fig. 3 into the pump manifold (Ref #44). 17. Re-attach intake siphon assembly and repairs are complete.
