LEVELING 1. 1. If legs are used, adjust the leveling legs of the storage bin until the unit is level and all four(4) legs are in sold contact with the floor. Leveling is very important to obtain proper draining and to maintain the proper level in the water pump pan of the ice cuber. Note: If the bin is to be installed flush to the floor, the bin must be sealed to floor with an approved mastic such as Dow R.T.V. #732, 734, or G.E. #102, 108. This is an N.S.F. requirement and is the respon- sibili

Water supply flowing pressure must not exceed 50 PSI. STARTING THE UNIT After the ice cuber has been unpacked and leveled and all plumbing and electrical connections have been made, start the unit, and check for proper operation. A cuber has three separate circuits: the water circuit, the refrigerant circuit and the e

Also check to see if the float valve is functioning properly and the correct water level is being maintained. Adjust if necessary. 2. Check the refrigerant circuit by making sure that the condenser fan is running. (This will be evident by air noise) Is the compressor running? (Feel the casing for vibration). Is the evaporator getting cold? 3. Check bin--harvest switch operation. )See procedure in manual). WATER DISTRIBUTOR HOLES ILL025 INSTALLATION INSTRUCTIONS FOR MOUNTING ON DRINK DISPENSERS F

WATER TREATMENT Depending on the water source for the ice maker, water treatment may be necessary to prevent calcium or lime scale deposits, bad taste and odor, chlorine problems, as well as slime growth. If these conditions exist, contact your Cornelius Distributor or Dealer for information on water treatment systems Cornelius offers. WINTER STORAGE If the unit is to be stored in an area where the temperature will drop below freezing, it is most important that all water lines be drained to prev

It is normal for the ice slab to be slightly thicker at the bottom and taper off in a slight wedge pattern at the top. The top row of cubes must have a complete pattern of ice on all four sides and the

Cycle time (CT) = freeze time plus harvest time, in minutes and seconds. 1440 divided by CT = number of cycles per 24 hours. Measure weight of ice from one cycle in pounds and fractions of a pound. Example: Weight/cycle x cycles/day = total production/24 hrs. Compare to the production tables * If water cooled, be certain water regulator valve is set to maintain 225/235 PSI head pressure.
