USING YOUR ICE MACHINE
Ice maker operation
• Make certain water pressure is at least 20 psi and no more
than 120 psi and the water is turned on.
• The unit must be installed level for proper ice maker opera-
tion.
• The shutoff arm wire must be down in its lowest position for
the ice maker to operate.
• When the freezer section and ice maker unit has sufficiently
cooled, the ice maker will harvest ice cubes automatically.
• When the ice bucket is full, the ice maker will automatically
shut off.
• You may manually stop the ice maker by raising the shut off
arm to the locking position at the up most position.
Arm down, ice maker
will operate
Arm up, stops operation
When operation of the appliance is to be discontinued for any
length of time, the ice cube cavity in the ice maker should be
emptied and dried. The water supply and power supply should
also be shut off and the ice bucket should be emptied and
cleaned.
If the ice is not used regularly, it will clump together with time.
For best ice results, discard ice in the bin as required and allow
the ice maker to make a new fresh batch of ice.

Turning on the ice machine
After connecting the water supply, and setting your ice machine
in place plug the power cord into the wall receptacle. Then
place the switch located in the grille (see Figure 8) to the “ON”
position. The temperature control is factory preset, allow the ice
maker to run for 24 hours so the interior temperature will sta-
bilize. If you wish to adjust the interior temperature use a small
bladed screwdriver pushed through the right hand side of the
grille to turn the temperature control shaft. Turning it clockwise
will make the unit colder. Turning it counterclockwise will make
it warmer. Turning it counterclockwise until it stops will shut off
the compressor and fan motor.

Should you turn off your control, allow at least five (5) minutes
before restarting in order to give the motor control time to auto-
matically reset so that it can restart the motor. Electrical power
to your unit is controlled by the “ON/OFF” rocker switch located
in the front grille. (See Figure 8).
Water Fill Adjustment
If the water fill needs to be adjusted, turning the “water adjust-
ment screw” (see Figure 9) clockwise increases the fill amount,
turning it counterclockwise decreases the fill amount. One com-
plete revolution will affect fill by 40cc.
Do not turn the “water adjustment screw” more than (1) 360°
revolution in either direction. Further adjustment than (1) revo-
lution could damage the ice maker module.
