GENERAL INSTRUCTIONS 1.1 INTRODUCTION Installation must be performed exclusively by authorized and specialized personnel, respecting the instructions in this manual. The manufacturer declares conformity to the applicable directives, and provides every single machine with a declaration of conformity therewith. Should the machine be supplied with a remote condenser unit, it is the responsibility of the installer to check all connections and to issue a declaration that the installation was duly performed and is in accordance with the aforementioned directive. The certificate of guarantee, which is found in the documentation, must be read, filled out and signed by the installer and by the client, and sent back to the manufacturer, otherwise the guarantee will be considered void. 1.2 INSTRUCTIONS FOR YOUR SAFETY To carry out cleaning and maintenance operations in total safety, we call your attention to the following “Basic safety instructions” : • do not touch the machine with wet or humid hands or feet • do not work on the machine barefoot • do not insert screwdrivers, kitchen utensils or other objects between the guards and moving parts • before carrying out ordinary cleaning or maintenance operations, disconnect the machine from the power supply by turning off the main switch and disconnecting the plug. • do not pull on the power cord to disconnect the machine from the power supply It is most severely prohibited to remove the guards or safety devices to perform ordinary maintenance operations. The manufacturer declines any responsibility for accidents caused by not observing the instructions above. Before putting the machine in operation, it is necessary to carefully clean the inside of the cell as indicated in paragraph 4.2. OFF!! 1.2.1 PRECAUTIONS FOR LOADING AND UNLOADING PRODUCTS LOADING • When loading the machine, use kitchen gloves to avoid burns due to contact with hot pans or trolleys. UNLOADING • At the end of the chilling and/or freezing cycle, open the doors slowly until the fans stop. • Extract the core probe(s) from the product and place them on the probe holder. • Use suitable gloves for cold pans and trolleys. 2 G E N E R A L I N S T R U C T I O N S 1.2.3 DANGEROUS USE OF SHARPENED PROBE Use of the probe is permitted only for authorized personnel trained in the use of the chiller. The core probe must only be used for the purpose for which it was designed: measuring temperatures at the center of food products to be chilled and/or frozen. 1 Handle the probe with care, because the end of it is sharpened to make it easier to insert in the products to be chilled and/or frozen. The ergonomic grip allows for correct insertion and extraction. 60 50 40 1.2.4 DANGEROUS USE OF HEATED PROBE 30 Use the probe heating function only if the probe is inserted in the product that has been frozen. 20 10 To avoid risk of burns, do not touch the probe shaft after having activated the heating function and/or having extracted the probe from the product. 1.2.5 IMPROPER USE OF THE UV LAMPS The sterilization function with UV lamps (optional) must be used solely and exclusively for the purpose for which it was designed: sterilizing the inside surfaces of the cell. UV Long-term exposure to or observation of UV lamps that are on turned on can cause eye irritation. 1.2.6 PERIODIC STAFF TRAINING Periodically train all staff authorized to work on or with the machine (installer, user, maintenance technician) concerning the safety instructions. DEB Blas AG Chill t er To avoid accidents or damage to the equipment, periodically instruct staff on the use and maintenance of the chiller, referring to this manual which must be kept near the machine, in a known and easily accessible place. 3 1.3 LOADING PRODUCTS Avoid covering pans and containers with lids or insulating films: the larger the food surface exposed to contact with cold air, the less the chilling time will be. Use pans and containers that are as shallow as possible, and in any case no deeper than 6.5 cm. For best results we suggest loading the containers with 3.5 kg of product with a maximum thickness of 8 cm for rapid chilling, or 5 cm for rapid freezing. For difficult and/or fatty products, reduce the thickness even further. Take care that there is enough space between pans, so as to allow sufficient air circulation. 0,5-2 cm If the machine is not fully loaded, spread the pans and the load evently throughout the entire height, avoiding concentrations. Place the pans in the innermost part of the pan holder, taking care that they are as close as possible to the evaporator. In the case of trolley models, make sure that the trolley is placed in the center of the chamber. Do not overload the machine beyond the limits set by the manufacturer.

Therefore, before inserting the product to be chilled, perform an empty run of a SOFT or HARD cycle. 1 In order to avoid damage to the machine, do not leave warm products in the chamber. As soon as the product has been placed in the chamber, start the chilling or freezing cycle immediately . 1.3.2 CORE PROBE The core probe must be correctly placed in the center of a product of a large size or cut, taking care that the tip of the probe does not protrude from the product or touch the pan. In order to avoid undesired contaminations, the probe must be cleaned and sanitized before each working cycle. For best results we suggest loading GN 1/1 containers with 3.5 kg of product with a maximum thickness of 8 cm for rapid chilling, or 5 cm for rapid freezing. For difficult and/or fatty products reduce the thickness even further. 1.3.3 TEMPERATURES Avoid leaving foods to be chilled and/or frozen at room temperature for long periods. The more moisture that is lost, the less tender the food will be. It is advisable to start the rapid chilling and/or freezing cycle as soon as preparation and/or cooking is finished, taking care to insert the food in the chiller at a temperature of not less than +70°C. Cooked food can even be placed in the chiller at very high temperatures (>100°C), as long as the chamber has been pre-cooled. Keep in mind however that the cycle reference times start from +90°C (from +90°C to +3°C in the rapid chilling cycle; from +90°C to -18°C in the rapid freezing cycle). 60 50 40 OK!! 30 20 10 1.3.4. CONSERVATION Chilled and/or frozen food must be properly covered and protected (with film, with a hermetic lid or better still vacuum packed) and it must have an adhesive label that shows, in indelible writing, the contents, the preparation date and the assigned expiration date. NO!! Chilled food must be conserved in a refrigerated compartment at a constant temperature of +2°C. Frozen food must be conserved in a refrigerated compartment at a constant temperature of -20°C.

This cycle is especially suitable for delicate products such as: mousse, puddings, creams, desserts, vegetables and foods of limited thickness. • “HARD” CHILLING This cycle rapidly reduces the temperature of foods down to +3°C at the core, with a working temperature that oscillates between -15°C and +2°C. This cycle makes it possible to substantially reduce working times and is suitable for foods with a high fat content, high density foods, large pieces or packaged foods. 2 • SHOCK FREEZING With the rapid freezing cycle, the food’s core temperature is lowered to -18°C , with a working air temperature that can reach -35°C/-40°C. This operation must take place in a maximum time of 4 hours, but the length of the cycle is influenced by several different factors such as the type of food, thickness, initial temperature, type of container used, etc. • CONSERVATION The conservation mode is automatic at the end of the rapid chilling and freezing cycle. In fact, at the end of the rapid chilling cycle, once the final temperature of +3°C is reached at the core of the food, a constant air temperature of +2°C is maintained. At the end of rapid freezing, when the core temperature reaches -18°C, a constant air temperature of -20°C is maintained. The duration of the conservation mode is unlimited: it can only be interrupted by a new command from the operator. It is not advisable to use the equipment as a simple “conservation unit”, nor to continuously open and close the door during this function. The conservation mode is to be considered as a temporary passage between chilling and/or freezing and refrigerated conservation which must take place in the correct equipment. 7 2.1.1 DESCRIPTION OF SUPPLEMENTARY FUNCTIONS • DEFROSTING This function is only available in the models with SHOCK FREEZING. It can be activated by the operator if frost has formed on the evaporator. Defrosting must take place with the door open and it has a reset duration of 30 minutes. The fans draw in warm air from the outside, and with the compressor off they rapidly defrost the evaporator. Warning: This function must not be used for the defrosting of frozen food products. • STERILIZATION (Optional) The U.V. lamps perform a microbicidal action and sterilize surfaces, liquids and the air in the working chamber. It is an independent cycle that can only work when no other cycles are in progress and it has a reset cycle of 30 minutes. The thermal range for maximum disinfecting performance is between +20°C and +40°C. During the cycle it is also possible to insert and sterilize kitchen utensils such as knives, carving forks, etc. A special safety device causes the lamps to shut off after 4 seconds if the chamber is open; when the door is closed the cycle starts up again normally. It is advisable to use this function at the end of the working day, after having cleaned the machine, and at the start of the working day before starting the pre-cooling of the chamber. • HEATING OF THE CORE PROBE The probe heating function (patented) is associated with the SHOCK FREEZING cycle in the models HCM and HCC: by rapidly increasing the temperature of the probe shaft, the layer of ice present on its outer surface is melted, making it easier to extract it from frozen products. • PRINTER Data concerning time, temperatures, and alarms for each chilling and/or freezing cycle, can be printed with a printer built-into the control panel (excluding models HC 51.20 and HC 101.35) or with portable printers which can be connected to the control panel. For further information see “Printers”, paragraph 3.3. 8 2.2 AUTOMATIC MODE DESCRIPTION OF PA N E L S In AUTOMATIC mode the control of the chilling and freezing modes is carried out by the electronic board by means of the core probe that measures the temperature at the center of the product to be treated; the temperature of the air in the cell is measured by the air probe, which controls the minimum and maximum values that can be reached during the various phases of the cycles. The temperature of the air in the cell is shown on the “AIR TEMP” display, whereas the temperature at the core of the product is shown on the “CORE TEMP” display. 2 Once the preset temperature at the core of the product has been reached, the machine will signal the end of the cycle: the buzzer will sound for a few seconds, and the machine will automatically pass to conservation mode, indicated by the green flashing light. 2.3 MANUAL MODE In MANUAL mode the control of the chilling and freezing cycles is performed by the electronic board by means of a timer that regulates (in minutes) the length of the various cycles; the temperature of the air in the cell is measured by the air probe, which controls the minimum and maximum values that can be reached during the various phases of the cycles. The remaining time to complete the cycle is shown on the “TIMER” display with a value in hours:minutes, while the temperature of the air in the chamber is shown on the “AIR TEMP” display. At the end of the preset time, the machine will signal the end of the cycle: the buzzer will sound for a few seconds, and the machine will automatically pass to conservation mode, indicated by the green flashing light. 9 During manual mode operation of cycles it is possible to display the temperature of the core probe by pressing the SONDA key. In this case the probe behaves like a simple thermometer and does not influence the control of cycles. The time remaining will be automatically displayed after a few seconds. 2.3.1 TIME SETTING During functioning of the chilling and freezing cycles in MANUAL mode, the value of the time remaining to complete the cycle, shown on the “TIME” display , can be modified. Press the + and - keys used to increase or decrease the length of the selected cycle. The new value of the time shown in the display is acquired automatically after 3 seconds. To modify times set by default, refer to the chapter “Parameter Programming” 10 2.4 PROBES TEMPERATURES AND DISPLAYED - DESCRIPTION OF PA N E L S In each chiller there are two temperature probes: - the “air” probe located inside the cell, for masuring the air temperature, which is always shown in the display “AIR TEMP” (disabled during sterilization and defrosting cycles) the “core” probe, movable and shaped like a shaft, to measure the emperature at the core of the products. 2 The temperature related to the core probe is shown on the “CORE TEMP” display only during the operation of cycles in AUTOMATIC mode. During operation in MANUAL mode it is possible to view the temperature of the core probe by pressing the PROBE key. In this case the probe acts as a simple thermometer and has no influence over the control of the cycles. The remaining time will be displayed automatically after a few seconds. In the models HCM and HCC the core probe has a device which heats the tip, making it easier to extract from frozen products. Press the PROBE HEATING key, wait for the green indicator light to turn off and extract the probe. Safety conditions to avoid unnecessary heating of the probe are: • no cycle in progress • cell door open • core temperature less than 0°C • heating time of not more than 5 seconds NB: if necessary, repeat the cycle after having waited at least one minute. 11 2.5 STARTING AND SHUTTING DOWN THE MACHINE The control panel was designed to guide the user and to suggest to him selection of the various cycles, with the illumination of the LEDs corresponding to the enabled buttons. Turn the machine on by pressing the ON button. The displays will show the temperatures of the air probe and the core probe. Choose the chilling and/or freezing cycle or the required supplementary function, and start the desired cycle by pressing the START button. The started cycle is indicated by the corresponding green LED being on. To stop any cycle or function in progress press the STOP button again. To shut down the machine, press the OFF. 2.6 EMERGENCY SHUTDOWN In case of emergency • press the OFF button to stop the machine • remove the power supply from the main board. OFF!!

ORDINARY MAINTENANCE The information and instructions contained in this chapter are intended for all personnel authorised to operate on the machine: the user, the maintenance man and even non-specialised personnel. 4.1 BASIC SAFETY INSTRUCTIONS To carry out cleaning and ordinary maintenance operations in perfect safety, kindly note the following basic rules: • do not touch the machine with damp hands or feet • do not operate the machine with bare feet • do not insert screwdrivers, kitchen utensils or other objects between the guards and the moving parts • before cleaning or carrying out ordinary maintenance, disconnect the machine from the mains by turning the main switch off and removing the plug • do not pull at the cable to unplug the machine from the mains. It is strictly forbidden to remove guards and safety devices to effect ordinary maintenance operations. The manufacturer declines any responsibility for accidents caused by not following these guidelines. Before starting the machine, it is necessary to accurately clean the inside of the cell as indicated in the following paragraph. OFF!! 4.2 CELL CLEANING ROUTINE MAINTENANCE To ensure hygiene and to protect the quality of the foods, the inside of the cell must be cleaned at the end of each working day. The shape of the cell and of the interior components make it possible to clean it using a cloth or sponge. Use water and neutral, non-abrasive detergents. The cell can be rinsed using a cloth or sponge dipped in water or a moderate jet of water (having a pressure that does not exceed the pressure of the system). 4 Do not scrape the surfaces with sharp objects. Do not use abrasive products, solvents or thinners. 4.2.1 STERILIZATION CYCLE We suggest you use this function at the end of the working day, after having cleaned the machine, and at the beginning of the day before starting the chamber precooling cycle. 19 4.2.2 EVAPORATOR WASHING Always use protective gloves during the following operations. HOW TO ACCESS THE EVAPORATOR: It is possible to gain access to the inside of the evaporator by loosening the screws located on the left side of the fan panel and opening it to the right (for the HC51/20 model the panel must be pulled down). HOW TO CLEAN THE EVAPORATOR To clean the evaporator you can use a brush by moving it vertically in the direction of the aluminium fins. When you have finished, simply shut the fan panel by following the above instructions in reverse order. Never use sharp objects. 4.2.3 CONDENSATION EMPTYING The models fitted with an integrated condenser unit are supplied with a special tray that collects the condensation and washing water and is located at the bottom of the machine. Empty and clean the tray periodically after having removed it from underneath the machine using the handle. 20 4.3 CONDENSER CLEANING For the chiller to operate correctly and efficiently, it is important that the air condenser is kept clean to ensure unhindered air circulation. HOW TO ACCESS THE CONDENSER: In models having an integrated condenser unit, access is gained to the condenser from the front. To remove the finned panel, loosen the two screws (A) at the bottom of the panel. After having cleaned the condenser, put the panel back in place and fix it using the screws. A For remote condenser units, remove the protection grid by lifting it and pulling it outwards. After having cleaned the unit, put the grid back by following the instructions in reverse order. ROUTINE MAINTENANCE The units can be used after they have been reassembled. Always use protective gloves, glasses and masks to protect the respiratory tract during cleaning. HOW TO CLEAN THE CONDENSER: 4 The condenser must be cleaned once every 30 days at the most. This can be done by using non-metal brush to remove all the dust and fluff from the condenser fins. We suggest you use a vacuum cleaner to prevent the dust from going into the environment. If there are grease deposits, remove them by using a brush dipped in alcohol. Do not scrape the surface using sharp or abrasive objects. 21 4.4 ALARM SIGNALS AND TROUBLESHOOTING The machine alarm signals can be divided in the following three categories: Machine block alarms This category of alarms is caused by safety devices that block the machine functions. To start the functions again the following must be done: • eliminate the cause of the problem. • turn the control panel off and on again to cancel the alarm signal. NB: this alarm category may require the intervention of a specialised technician. Display alarms with manual reset This category of alarms requires the intervention of an operator who, after having identified and eliminated the cause of the alarm and having reset normal working conditions, is capable of cancelling the alarm signal to permit the machine to start functioning again. press the START/STOP key. Display alarms with automatic reset This category of alarms is connected to safety devices that, when normal working conditions are restored, cancel the alarm signal and allow the machine to start functioning again and to end the work cycle. It is however important to check the cause of the alarm as soon as possible so that it can be eliminated. NB: if the cause of the alarms are not eliminated, they will be displayed again the next time the machine is turned ON. All the alarms are shown simultaneously by the red flashing light, by the buzzer, and by displaying the code shown on the time and/or temperature displays, The tables in the following paragraphs show the possible causes that generate each alarm, in order of probability, as well as the solutions suggested to eliminate them. 22 ALARM CODE PROBABLE CAUSE SUGGESTED MEASURES ALC Intervention of compressor magnetothermal cutout If it occurs at the first start-up, check for correct connection of supply cables to the terminal board and of the plug, if any: phases on L1, L2, and L3; neutral on N.

Check for proper insulation of pipes connecting the chiller with the remote condensing unit. If the chiller or the remote condensing unit have not been transported in a vertical position (i.e. on their back) or have been turned upside down during installation, do not turn them on immediately but wait at least 4 hours before doing so. 4h • inside the cell, they extract the air from the centre of the work chamber and convey it towards the evaporator. • in the air condensing units, the fans extract air through the condenser and convey it outside. I N S TA L L AT I O N INSTRUCTIONS Check the electrical connections. In models with a three-phase power supply, check the direction of rotation of the fans so that: 5 Check absorptions with the values shown on the dataplate. 41 Check the standard pressures and the intervention values of the pressure transducers referred to the “Pressure switch adjustment values” table. Check water connection with the pressure valve adjustment during operation as well as proper water condensation circulation. Run at least one blast chilling or freezing cycle in the manual mode. • Inform the customer on the correct utilisation of the chiller with specific reference to the use and requirements of that specific customer. • Installation and setting at work must be carried out by authorized personnel who must sign the guarantee certificate. 2 The guarantee will be valid only if the certificate, that is supplied with the documents, is read, filled in and signed by the authorized installer and by the Customer and sent back to the manufacter. 42 1 5.9 SAFETY AND CONTROL SYSTEMS • Door microswitch: stops chiller operation when the door is opened; in the event of a sterilizing cycle, the lights go off after 4 seconds (Fig.A).

Exposures high concentrations can cause irregular cardiac rhythm and even sudden death. If the product is nebulized or sprayed it can cause cold burns to the eyes and skin. It is dangerous for the ozone layer. Contact with the skin If the product is nebulized or sprayed it can cause cold burns to the eyes and skin. It does not seem to be dangerous if absorbed by the skin. Repeated and prolonged contact can cause loss of natural skin oils with consequent drying, chapping and dermatitis. • Ecological information It breaks down quite quickly in the troposphere. The products or decomposition have high dispersion features and thus have a low concentration. It does not promote photochemical smog (i.e. it is not part of the volatile organic compounds -VOC- in compliance with the UNECE agreement). Its ozone destruction potential (ODP) is 0.055 measured against a standard ODP of 1 for CFC11 (according to the UNEP definitions). This substance is regulated by the Protocol of Montreal (1992 revision). Product discharges into the atmosphere do not cause long-term water contamination. • First aid measures Inhalation Move the injured person away from the source of exposure to a warm place where he can rest. If necessary, administer oxygen. Practice artificial respiration if the person has stopped, or seems about to stop, breathing . In the event of cardiac arrest effect an external cardiac massage. Call for medical assistance straight away. Contact with skin Thaw the parts concerned using water. Remove contaminated clothes. Attention: in the event of cold burns, clothes can adhere to the skin. If the gas has been in contact with the skin, wash the part immediately and thoroughly with warm water. If symptoms occur (irritation or blisters) ask for medical assistance. • Disposal suggestions The best solution is to collect and recycle the product. If this is not possible, it must be destroyed in a plant that is authorised and equipped to absorb and neutralize it. • Measures to be followed in the event of accidental dispersion Make sure that the person eliminating the dispersion is suitably protected (using special apparatus to protect the respiratory tract). If it is safe enough to do so, isolate the source of dispersion. If the dispersion is modest and ventilation is sufficient, simply let it evaporate. For dispersion of large quantities: -ventilate the area; -contain the spilled material using sand, soil or other suitable absorbing material; -prevent it from penetrating in drains, sewers, basements and working excavations because the vapours can cause suffocation. Contact with the eyes Wash immediately with an eye-wash or clean water, keeping the eyelids apart for at least 10 minutes. Ask for medical advise. Ingestion Do not provoke vomit. If the injured person is conscious, make him rinse his mouth out and drink 200-300 ml of water. Request medical assistance immediately. Further medical care Treatment for symptoms and support therapy where indicated. Do not administer adrenalin or similar substances after exposure because of the risk of cardiac arrhythmia with the possibility of cardiac arrest. • Handling Avoid inhalation of high concentrations of vapours. Concentrations in the atmosphere must be reduced to a minimum and kept at the lowest reasonably possible level, below the professional exposure limit. The vapours are heavier than the air and for this reason it is possible that high concentrations form near ground level where ventilation is scarse. In these cases, ensure adequate ventilation and wear protective apparatus for the respiratory tract with a supply of air. Avoid contact with naked flames and hot surfaces because irritating and toxic products of decomposition may form. Avoid contact of the liquid with eyes/skin. • Fire-prevention measures Non inflammable. Thermal decomposition causes the emission of very toxic and corrosive vapours (hydrogen chloride, hydrogen flouride). In the event of fire, use breathing apparatus and suitable protective clothes. Fire extinguishers Use extinguishers suitable for the type of fire. • Toxicological information Inhalation High concentrations in the atmosphere can cause an anaesthetic effect and possible unconsciousness. Exposure to very high concentrations can cause irregularities of cardiac rhythm and even sudden death. 44 6.
