4. If water-cooled, are inlet and drain connections to condenser correct to prevent “water hammer”?
5. Are drain lines separate and vented?
6. Is there 6I clearance on all sides and top for proper air circulation?
7. Does the water curtain move freely, and does the float valve shut off incoming water to the water pan?
START-UP AND CHECK OUT
1. Turn the Cuber’s power switch to the clean (pump only) position. The water pump only should be opera-
tional. Wipe the top extrusion briskly with a ScotchBrite pad. Check for an even, steady flow of water over
evaporator top extrusion and down over evaporator surface. Check that all ports of the water distribution
tube are open for even water discharge. The water pan should refill and the float should stop the incoming
water sup-
ply.
Power Switch
NOTE: On the IACS222/IWCS227 to service the float valve:
1. Compress the John Guess fitting remove the 1/4” tubing.
2. Remove the screws that hold the float bracket to the liner wall.
3. Carefully remove float strainer and bracket as one assembly.
4. Reverse procedure to reinstall.
Should service be required on the float valve or strainer, turn the water supply off, loosen the float,
hold down nut and remove the float and strainer as an assembly for ease of service.
2. Place the Cuber’s power switch in the ON position. After a 2-second delay the compressor will start. The
condenser fan will operate when the condenser sensor signals the circuit board its temperature is 100_F
(38_C). The water pump will operate when the evaporator cools to 25_F (–3.9_C). Depress the manual
harvest switch (on the circuit board). The fan motor will stop and the water dump valve will open. In 3 se-
conds the hot gas solenoid will open and 15 seconds after depressing the manual harvest switch, the water
pump and dump valve will close terminating the dump cycle.
3. Hold the water curtain open for a maximum of 30 seconds; the Cuber should shut down. Release the water
curtain(s). When the curtain(s) closes, there will be a 2-second delay, then the compressor will start and
the start-up process should begin for the next ice-making mode.
4. If all Cuber operation is as stated, allow product to operate and produce one slab of ice, then discard the
ice. Allow the Cuber to continue operation to fill the storage bin.
