INSTRUCTIONS FOR USE
When the ice maker thermostat senses the preset tempera-
ture for the ejection of the ice cubes, the fingers will start
to rotate, dumping any ice cubes and filling the mold with
water. When the storage container is full, the bail arm will
come in contact with the ice cubes. The bail arm cannot
return to the full down position and the ice production is
stopped until the bin is emptied, or ice cubes are removed.
To prevent water from splashing out of the mold assembly
while travelling in your recreational vehicle, raise the bail
arm to the full UP/OFF position about 1-1/2 hours before
departing. This will allow the water in the mold to freeze.
WATER SUPPLY
The water supply system must have a minimum pressure
of 15 pounds per square inch gauge (psig). A 1/4" diameter
water line to the water valve should be used at the rear of
the refrigerator. The water line must have a manual shutoff
valve placed where it is easily accessible.
The maximum water level is represented by a thin line. It
is essential that the water level does not exceed this line!

If necessary, change the water flow by adjusting the water
supply. For instructions, see ADJUSTING THE SIZE OF
CUBES.
ADJUSTING THE SIZE OF CUBES
 I f the ice maker was cleaned and drained, no ice
cubes will be dumped into the bin during the first
cycle.
The first few cycles may have small cubes due to air
trapped in the water lines. The first container of ice cubes
should be dumped if the water system has been winterized
or not used for several weeks. Once the ice maker has
run through several cycles and if cubes are too small or
sticking together, adjustment is necessary on the amount
of water entering the mold.

TO ADJUST THE SIZE OF CUBES, FOLLOW THESE
STEPS:
1.  R emove the protective cover from the ice maker
mechanism. Using a flat-head screwdriver, place
the tip of the screwdriver in the slot. Twist the
screwdriver blade gently to loosen the cover.
2. Locate the adjusting screw under the protec-
tive cover. Turn the screw counterclockwise to
increase the size of cubes.
3. Turn the screw clockwise to decrease the cube
size or if the mold is overfilling, and the cubes
are stuck together.
 T o prevent overfilling, do not turn the adjustment
screw more than one revolution at a time. Allow
the ice maker to cycle several times before another
adjustment is made. Be sure to replace the protec-
tive cover on the cycle after the adjustments are
complete.
