WATER LEVELS, CYCLE TIMES, AND REFRIGERANT CHARGES
Water fill level (Top of tank to level in control tube,inches)
Approximate cycle time, min.
Approximate harvest weight, lb.
Refrigerant Charge, ounces (R-404A)
** Values are for Air-cooled model at 90°F air/70°F. water temperatures with cuber
adjusted to produce fully-formed ice. Greater capacity can be obtained by reducing the
water fill level (lowering the high-level probe) to produce ice with larger dimples. A
slight adjustment of the probe will result in a noticeable effect on dimple size. The
control stream will not rise over the dam with lower water fill levels than indicated
above.
CAUTION: REFRIGERANT CHARGES MUST BE ACCURATELY WEIGHED.
Consult the specification and troubleshooting guide if variations from the following
description of operation are noticed:
1. Remove the top and front cabinet panels.
2. Be sure that the "ICE-OFF-WASH" switch is in the center (OFF) position.
3. Turn on supply water and power. Be sure that condenser liquid is ready for use
before turning power on. Check for leaks in water/liquid supply connections.
4. Be sure that pump hoses are connected, then put about one pint of clean tap
water into the circulation system to lubricate the pump seal.
5. Move the "ICE-OFF-WASH" switch to the right "WASH" position and observe
the water fill cycle and the pump running. If all water distributor holes do not
produce full streams and the appearance of air is evident in the tube, pinch the
plastic tube connected to the water solenoid valve outlet while water is running
until the streams are full all the way across the distributor tube. Water fill is
complete when the water in the liquid level control tube reaches the high-level
probe. At this time observe that the water shuts off and that there are no water
leaks (dripping into the drain pan).
6. Pull the right end of the water plate down, stretching the springs until the pump
stops, and hold until the pump does not re-start when released. The water plate
will open fully to dump the batch of water previously taken in, then close
immediately. The water plate should stop whin it is fully closed, and the water
fill cycle will repeat.
