Great care must be employed when working with high pressure CO2, and in no cases should the normal operating pressure of 2.4 bar (35 psi) be exceeded. Description The Viscount IV series is a range of chillers providing either still only or still and carbonated water outputs, and can include up to 2 syrups, which are generally cooled on carbonator models and at ambient temperature on still only models. The units all incorporate an ice bath to provide the capacity for extended drinks performance, and share the same fridge, bath and control components. The schematics from Page 4 onwards show the individual circuits for water, carbon dioxide and syrup. Page 2

3 Introduction Description continued On carbonator models, carbonated water is generated in the carbonator can and is dispensed via a solenoid valve, flow adjuster and the dispense harness, under the pressure generated within the can. The can is replenished by a water pump which is controlled by the PCB and a level probe within the can. For a still drink, water passes through the pressure regulator, used to set the flow rate, through the pump which is not energised for still water dispense. It then is passed through the stainless steel water coil in the ice bath to the dispense harness via a solenoid valve. Both still and carbonated water are dispensed from the same tube within the dispense harness. If fitted, syrups are chilled via stainless steel coils in the ice bath, and dispensed via individual syrup pumps. The still only models do not include a water pump, the flow rate being controlled by a proprietary flow regulator. Water is chilled via the same water coil within the ice bath as the carbonators, but is dispensed directly via the dispense harness. No syrup cooling is provided on the still only models, the syrup merely being dispensed via the syrup pumps. Viscount IV carbonator models are controlled by the Booth CLIP2 PCB which provides the following features. Water pump timeout - interrupts the water pump supply after 55 seconds continuous operation Electronic ice probe control - replaces the conventional thermostat used on earlier models Fridge hi-side protection - interrupts the compressor supply if the operating temperature rises above its limit Fridge overrun protection - interrupts the compressor supply if the output is detected as being on for 10 hours continuous Refer to the Fault Finding section on Page 12 for further information.

7 Installation & Commissioning Installation 1. Secure the unit through top fixing holes to the host machine. 2. Connect the water inlet at the point in the top, left rear of the chiller. 3. If syrup pumps are fitted: Insert the syrup dip tubes into the syrup containers. 4. Place the overflow pipe into suitable container. 5. Connect the dispense harness to the dispense nozzle on the host machine. 6. Make all electrical connections between the chiller and the host machine. Commissioning 1. Remove the plastic cover on the combined bath fill and overflow, fill the bath with cold water until it overflows from the outlet. 2. Carbonator Only: Ensure the gas bottle regulator is set to 2.4 bar (35 psi) and connect the braided CO2 pipe to it. 3. Ensure there is a water supply available to the unit, and that any isolating valves are open. 4. Turn on mains electrical supply to unit by overriding the door interlock on the host machine (refer to the host machine instructions for this procedure). 5. With mains power and water on the following will happen. The agitator will start to turn. The compressor and fan will start. Carbonator Only: The water pump will start and fill the carbonator can. 6. After approximately 10 seconds, press and hold the flush switch. Carbonated water will be dispensed until the carbonator can is emptied. Allow the can to vent for at least 5 seconds to allow any air to be purged from the system. Then release the flush switch. The pump will then switch on and fill the carbonator can. 7. If Syrup pumps are fitted: Prime the syrup pumps using the method recommended in the instructions for the host machine. 8. If Syrup pumps are fitted: Set the syrup flow rates, refer to the host machine instructions. Important: Correct carbonation will not occur until ice has started to form in the bath and the water temperature has fallen below 5 C. Note: If the bath has been filled to the point of overflow, approximately half a litre of water will be displaced as ice forms in the bath. 9. Test both still and carbonated drinks for correct operation. Page 7

8 Cleaning Important: The frequency of the following cleaning procedures should be determined locally and may vary depending on machine usage and environmental conditions. Warm water should be no higher than 45 C. After any cleaning procedure, dispense 3 drinks from each selection to ensure all cleaning fluid residue is flushed out. Routine Clean - Use the appropriate methods below for parts in contact with food products. Important: It is recommended that the routine clean procedure be performed at least weekly. Multi Purpose Disposable Cloth Use the cloth to apply the cleaning agent. Submerge a clean cloth into the cleaning agent (concentration recommended by manufacturer s instructions). Remove the cloth and remove excess water. Clean the dispense components wiping the cloth over the entire area re-submerging the cloth as necessary. Rinse the cloth in clean warm water and wipe off excess cleaning agent residue and soil. Dry using disposable paper towels, replace dispense components. Spraying on Cleaning Agent Remove the dispense nozzles from the dispense bush. Liberally spray the cleaning agent at the concentration recommended by the manufacturer onto the dispense components ensuring that the whole area has been covered. Finish the clean by exchanging the cleaning agent for warm water, remove the soil with a multi purpose disposable cleaning cloth and dry the components with disposable paper towels. Food Grade Antibacterial Wipe Remove the dispense nozzles from the dispense bush, wipe the dispense components with the food grade antibacterial wipe, remove all visible soil. Replace dispense components. Soaking Post Mix Dispense Nozzle Remove the dispense nozzles from the dispense bush and submerge the dispense components into the cleaning agent solution. Leave the dispense components submerged for the desired contact time (2 to 10 minutes). After the contact time is over remove the dispense components, rinse in warm water and dry using disposable paper towels. If not removable, clean using cleaning agent solution and brush. Page 8

9 Cleaning Deep Clean - Parts in contact with food products Important: It is recommended that the deep clean procedure be performed at least monthly. Remove dispense components, pre clean using a damp multi purpose disposable cleaning cloth soaked in warm water. Soak cloth in cleaning agent solution, remove excess water and clean dispense components. Using a brush, brush dispense head to dislodge any dried on soil. Remove soil with the cloth. Rinse dispense head with a new multi purpose disposable cleaning cloth soaked in warm water until all soil and cleaning agent residues have been removed. Soak multi purpose disposable cleaning cloth in disinfectant solution, apply to dispense component, ensure that the whole area is wiped. Leave for 10 minutes. Rinse off disinfectant using multi purpose disposable cleaning cloth that has been soaked in clean warm water. Dry dispense component with disposable paper towels. Refit all dispense components. General Cleaning - Parts not in contact with food products Important: It is recommended that the procedure should be performed at least every 6 months. Condenser. At regular intervals, determined by local environmental conditions, the condenser should be thoroughly cleaned with a small stiff brush and/or a vacuum cleaner. Do not use screwdrivers or other sharp implements which may puncture the fins. Warning: Failure to clean the condenser can shorten the life of the compressor causing premature failure of the unit. Outer Panels. Clean the outside panels, pay particular attention to the edges of the panels where spillage from ingredients could have ingressed and the area around the base of the unit. If necessary, remove the unit and thoroughly clean around the base and floor. Important: If ingredients are present inside the unit, the cause must be found and rectified. Page 9

10 Cleaning Sanitisation Important: It is recommended that the procedure is performed at least every 6 months. Prepare the Unit 1. Purge the carbonator can by operating the flush switch until the carbonator is empty and CO2 is dispensed for 5 seconds. Disconnect electrical power before the carbonator can refills. 2. Remove the top & front panels. 3. Ensure that the waste bucket is in place. 4. Lift syrup dip tubes above liquid level in product container & prime the pumps to empty the lines, then place in a container of clean water and prime through to dispense nozzle then lift out of water & continue until empty. 5. Carefully follow the manufacturer s instructions and prepare a solution of proprietary sanitising fluid such as DIVERSAL BX4A. A clean 5-litre syrup container is ideal for this operation. 6. The water bath should not need cleaning. In the unlikely event it does require cleaning, refer to Cleaning the Ice Bath on Page 11. Sanitise the Water System 7. Where a filter is fitted remove the cartridge, put sanitiser into the chamber and flush through. Where a complete filter is fitted, dummy filters are available for this purpose. or alternatively 8. Disconnect flexible water inlet tube from the water supply and place the end into a container of sanitising fluid. If the unit being sanitised does not incorporate a water pump, flushing through of sanitising solution can be achieved either using a pressurised container, or by using a siphon. I the latter case, the sanitiser fluid needs to be held at a height sufficient to allow fluid to flow through the chiller. 9. Switch on power & allow the water pump to begin refilling the carbonator. 10. Draw 1 cup of carbonated water followed by 1 cup of still water to ensure all tubes are full of sanitiser. 11. Switch off power & leave to stand for period recommended by sanitiser manufacturer. 12. Follow Routine Clean procedure to clean dispense nozzles. Page 10

11 Cleaning Sanitise the Syrup Lines 13. Switch on the main power. 14. Place dip tubes into the container of sanitising fluid & operate the syrup priming switches until the fluid pours from the dispense nozzle. 15. Switch off power and leave to stand for the period recommended by the sanitiser manufacturer. Recommission the Unit 16. Switch on power supply. 17. Place syrup dip tubes into a 5-litre container of clean cold water and flush 1 litre through each syrup line. 18. Reconnect inlet water supply tube to machine supply & dispense 3 litres of still water. 19. Dispense 3 litres of carbonated water. 20. Re-connect syrup tubes to the appropriate syrup containers and refit all covers. 21. Prime waters and syrups through to dispense nozzle & check drink strength with a brix cup. 22. Close vending machine door & test vend all cold drinks. Cleaning the Ice Bath. (If required) 23. Drain the bath by siphoning off the water into a suitable container. Ensure all ice is melted and drained off using warm water (Max 45 C) if necessary. 24. Fill the water bath with sanitiser solution until the solution starts to spill from the bath overflow. 25. Switch off power & leave to stand for period recommended by sanitiser manufacturer. 26. Siphon off water bath and refill with cold water. Important: The ice bath should be siphoned off and refilled a second time as any sanitiser fluid left in the bath could cause the unit to freeze up due to the use of ice probes for control purposes.

To Remove from Host Machine 1. If fitted, place syrup dip tubes into a container of clean water and prime through until the water is coming from the nozzle. Whilst still priming, lift the dip tubes above the level of the water until all tubes are empty. 2. Siphon all water from the Ice Bath. 3. Disconnect water supply, CO2 supply, and all electrical connections. End of Life Disposal It is illegal to simply scrap a refrigeration system. Before a fridge can be scrapped it must first have the gas removed by a specialist using specialist equipment. Please contact Booth Dispensers for further information and a quotation for disposal. Transportation Important: This unit must be transported in an upright position As with all refrigeration systems, irreparable damage can be caused by laying the unit on its side or even transporting it upside down. Where the unit is transported by a 3 rd party agent, the packaging should always be marked in a conspicuous manner, indicating the correct upright position in which it must be handled. If a unit has been transported incorrectly it should be placed in the correct upright position and left for 24 hours before attempting to run the system. Failure to observe the above precautions could seriously damage the system. Page 16
