Installing Water Supply Line to
Ice Maker
Supply line installation must comply with all applicable
plumbing codes. The ¼” tubing and any other plumbing
materials required should be obtained locally.
The ice maker should be connected to a frequently used
cold water line to ensure a fresh water supply. Be sure
to leak test all connections after the water supply has
been turned on.
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 fill 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 fill
must be checked and the fill switch must be adjusted if
needed.
The correct water fill volume is 102 - 130 cc. To measure
the fill volume, test-cycle the Ice Maker and collect
the water. Measure in a container calibrated in cubic
centimeters (CC).
The fill volume is adjusted by increasing or decreasing
the length of time the water fill switch remains closed.
To adjust the water fill switch, first determine how much
water is needed. The adjusting screw is calibrated so
that one complete revolution changes the water fill
about 18 cubic centimeters. Turning the screw clockwise
decreases the fill, while turning counterclockwise
increases the fill.
EXAMPLE: An Ice Maker is test-cycled and the water fi ll
sample is 158 cubic centimeters. Subtracting 130 cc from
158, the adjustment needed is 28 cc. Since one turn
of the adjusting screw changes the fi ll 18 cc, 1-¾ turn
clockwise would reduce the fi ll about 28 cc, the desired
amount. (This example is for manual models only.)
Test Cycling Ice Maker
Operation of the ice maker, water refilling, and controlled
ice storage, require proper functioning and timing of all
components.
Consider the following:
•
Has refrigerator been properly installed and
connected to sources of electrical power and water?
•
Has freezer compartment evaporator pulled down to
temperature?
•
Have several ice making cycles been completed
and is the Ice Maker in the Freeze Cycle?
•
Do the ejector blades make two revolutions per
cycle? Is ice stored on blades after harvest?
•
Is the water solenoid wired in series with the mold
heater?
It may be necessary, on occasion, to test-cycle an ice
maker to check its operation. This can be done on
the repair bench or while mounted in the refrigerated
compartment.
If ice maker is in an operating freezer, take precautions
against the formation of condensate by allowing the cold
metal components to warm up before removing the front
cover. This can be expedited by cycling the assembly
with the cover in place and water supply valve closed.
To manually cycle the ice maker, slowly turn the ejector
blades clockwise until the hold switch circuit to the motor
is completed. When the motor starts, all components
except the ice maker thermostat should perform
normally. Once the ice maker completes its cycle,
remove the front cover.
To replace front cover:
1. Ensure that ice maker is at room temperature before
removing
cover.
2. Place straight blade of screwdriver in slot at bottom
of Mold support and pry cover loose.
If further test cycling is necessary, place screwdriver
blade in slot located in the motor drive gear and turn
counterclockwise until the hold switch circuit to the
motor is completed.
A vertical cold water line should be selected for
the water supply. If a vertical line is not available, a
horizontal line may be used, providing the connec-
tion is on the side or top of the pipe, but not on the
bottom. Scale and foreign material in the pipe could
cause stoppage of water flow if the connection is
on the bottom.
