START-UP INSTRUCTIONS
WATER LEVELS, CYCLE TIMES, AND REFRIGERANT CHARGES
CAUTION: REFRIGERANT CHARGES MUST BE ACCURATELY WEIGHED.
1. With the "ICE-OFF-WASH" switch in the center (OFF) position, turn on the
supply water and power.
2. Pour about one liter of potable water into the circulation system to lubricate the
pump seal.
3. Move the "ICE-OFF-WASH" switch to the right (WASH) position and observe
the water fill cycle and the pump running. 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.
4. 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, then close immediately. The water
plate should stop when it is fully closed, and the water fill cycle will repeat.
5. After the water fill is complete move the "ICE-OFF-WASH" switch to the left
(ICE) position and observe that the compressor (and fan in "A" models) starts,
and the water pump continues to run.
6. Test the bin thermostat by holding some ice against the capillary tube. If
necessary, adjust the thermostat so that the ice maker stops within 30 seconds
after ice contacts the capillary tube.
7. Be sure that the drain pan, ice chute, and deflector are in place, and that the
electrical control box cover is secured, then replace the cabinet panels. Start
with the SIDE panels, then the FRONT panel. Secure the FRONT panel with
