30 Part Number 020002365 08/25/2015Installation Section 2Preparing Ice BankBUILDING AN ICE BANK1. At this time, fill the unit water bath tank to the top,or within 1/2" (13 mm) of the top minimum, of theoverflow tube. Use a garden hose or another watersupply to do this.NOTE: A manual fill valve is incorporated into the watercircuit to the carbonator tank. This valve can be used tomanually add water lost for any reason. Do not leave thisvalve ON constantly, only use it for filling and topping off.The water bath must be drained, flushed, and refilled everysix months.2. Main power to unit must be on. Power delay of 30seconds occurs when power applied. "Pd30"3. Press COMP/AGIT switch on keypad display.4. Agitator will come on immediately and compressordelay will start. "Cd99" will count from 180 to 0.NOTE: Turn this switch OFF to perform any operations in thewater bath area.With water bath water temperature of 65°F (18°C), ice mustbegin to form on the evaporator coils in approximately 2hours. The unit will build a full ice bank in approximately 4to 6 hours (depending on ambient water temperature).Drain TubeOverflow TubeTab ClampWater Bath Tank5. Turn on the main water supply to the boosterassembly. Verify the booster is plugged in and thatthe accumulator tank valve is open. (If the systemhas an optional “Out-of-Syrup” device, verify that it isunplugged.)6. Verify the pump is running. Place the valve on the rightside of the pump box in the purge position until all airbubbles have passed through the line. Turn the valveback to “dispense”. Plug the Out-of-Syrup device powercord into an appropriate wall outlet at this time (ifsupplied).NOTE: Verify that the pump box holding tank is full beforeproceeding.7. Turn on the circulator and carbonator. The carbonatormust run for approximately 1 to 3 minutes and shut off.The circulator must run continuously. Verify that wateris returning to the water bath through the return bulkhead fitting.ImportantWait until a thin layer of ice has begun to form on theevaporator before proceeding any further.8. Go to the tower(s) and brix the valves. Using a syrupseparator and volume cup, adjust the flow rate of thecarbonated water to two fluid ounces per second. Then,using the separator and a brix cup, adjust the syrupflow rate for a ratio of carbonated water to syrup to 5to 1.Installation ChecklistCheck all fittings and conduit attachments for leaks.Check all insulated connections to make sure thatthey are sealed. Observe the pump operations for leaks. Check the water bath for full ice bank.The stabilized water bath operating temperature mustbe maintained at 33°F (0.6°C) to 35°F (1.7°C). Close water bath feeder valve completely. |
