BOARD in relation to the time T2 necessary for the unit to reduce the evaporator temperature from 0˚C (35˚F) to -1 3˚C (8.5˚F) and of the ambient temperature, as illustrated in Table C. - Page 11 7. The DIP. SWITCH keys setting is made in consideration of the model and of the type of condenser used (air or water cooled). In Table B, page 12, are indicated the various lengths of the third portion of freezing cycle (Time mode) in accordance with the different combinations of the DIP.

Page 17: Principles Of Operation
Principle of Operation 11.1 How it works In the cube ice makers the water used to make the ice is kept constantly in circulation by an electric water pump which primes it to the spray system nozzles from where it is diverted into the inverted mould cups of the evaporator. A small quantity of the sprayed water freezes into ice; the rest of it cascades by gravity into the sump assembly below for recirculation. -

ambient temperature as detailed in Table C. Page 18. The electrical components in operation during this phase are: COMPRESSOR WATER PUMP WATER INLET SOLENOID VALVE HOT GAS SOLENOID VALVE The incoming water, passing through the water inlet valve and the flow control, runs over the evaporator platen and then flows by gravity through the dribbler holes down into the sump/reservoir. -

the service and inspection operations. IN OPERATION: The unit is running through the freezing and defrost cycle stopping automatically only at full bin situation. RE-SET/HI TEMPERATURE: To be selected to resume the unit operation when the ice maker shuts off due to the intervention of the condenser temperature sensor (too high condensing temperature). -

Maintenance and Cleaning Instructions 16.1 General The periods and the procedures for maintenance and cleaning are given as guides and are not to be construed as absolute or invariable. Cleaning, especially, will vary depending upon local water and ambient conditions and the ice volume produced; and, each ice maker must be maintained individually, in accordance with its particular. - Page 23 Fig. 11 6. (R134A Machines Fig. 8) NOTE With the system in CLEANING/RINSING mode the water pump is the only component in operation to circulate the cleaning solution in entire water system. 7. Let the unit remain in the CLEANING/RINSING mode for about 20 minutes then turn the program selector on STAND BY again. 8.
