INSTALLING WATER SUPPLY LINE TO ICE MAKER
Make sure the installation complies with all applicable plumbing codes.
The ice maker kit contains ¼” plastic tubing and the fittings required to connect the plastic tube to the
water valve at the rear of the refrigerator and the fitting on the supply water pipe.
The ice maker should be connected to a frequently used cold water pipe to ensure a fresh water supply.
Note: A vertical cold water pipe should be selected for the water supply. If a vertical pipe is not
available, a horizontal pipe may be used, providing the connection is on the side or top of the pipe, and
NOT THE BOTTOM. Scale and foreign material in the pipe could cause stoppage of water flow if the
connection is on the bottom.
Be sure to leak test all connections after the water supply has been turned on.
TEST CYCLING ICE MAKER
It may be necessary, on occasion, to test cycle an ice maker to check its operation. This can be done
while mounted in the refrigerator.
To manually cycle the ice maker, press the On/Off switch down to the lower position for 15 seconds.
When the motor starts, all the components except the ice maker thermostat should perform normally.
If a further test cycle is necessary, the water in the tray must be manually removed as a further
test cycle will bring more water into the tray and cause flooding.
If the ice maker is in an operating refrigerator and it has to be removed, take a precaution against the
formation of condensate by allowing the cold metal components to warm up before removing the front
cover.
WATER VALVE SWITCH – WATER FILL VOLUME
The amount of water fill is directly proportional to the length of time terminals “C-NC” of the water
valve switch are closed. Closing occurs when the switch plunger drops into a cavity formed in the cam.
Different water valves have different flow rates. For this reason, anytime a water valve is replaced, the
water valve switch must be adjusted.
The correct water fill volume is 90 - 120 cubic centimetres, or about 3 to 4 ounces. To measure fill
volume, test-cycle the ice maker and collect the water. Measure in a container calibrated in cubic
centimetres or ounces.
The fill volume is adjusted by increasing or decreasing the length of time the water valve switch
remains closed.
To adjust the valve switch, first determine how much more or less water is needed. The adjusting
screw is calibrated so that one complete revolution changes the water fill about 18 cubic centimetres.
Turning the screw clockwise decreases the fill, while turning counterclockwise increases the fill.
EXAMPLE: An ice maker is test-cycled and the water fill sample is 134 cubic centimetres.
Subtracting 120 cubic centimetres from 134, the adjustment needed is 14 cubic centimetres. Since one
turn of the adjusting screw changes the fill 20 cubic centimetres, ¾ turn clockwise would reduce the
fill about 4 cubic centimetres, the desired amount.
