SERVICE AND INSTALLATION MANUAL
Operation
HOW THE MACHINE MAKES ICE
Press the ON/OFF button in front panel to turn on
3 minutes, the machine will automatically
go into the ice-making stage
There are two distinct cycles: Freeze and
Harvest. During the Freeze cycle, water ows
to the evaporator surface. In the Harvest
cycle, the ice is released and water enters the
machine. A complete cycle can take 15 to 40
minutes, depending on ambient temperature
and operating conditions.
Freeze: During the Freeze cycle the compressor is pumping refrigerant, the fan motor is blowing air, and
the water pump is circulating water. When the batch of ice has been fully formed, the ice maker stops the
Freeze cycle and begins the Harvest cycle.
Harvest: During the Harvest cycle the compressor is still operating, power is supplied to the water purge
valve and hot gas valve. The water purge valve opens and allows the water pump to purge the water
remaining in the water tank, removing all impurities and sediment. This allows the machine to make clear
ice cubes and keep mineral build-up at a minimum. Then the water pump stopped. The hot gas valve
opens, diverting hot refrigerant gas into the evaporator. The gas warms the evaporator, causing the cubes
to slide as a unit off the evaporator and into the storage bin. The Freeze cycle will restart when all the cubes
drop into the bin.
HOW THE MACHINE USES WATER:
The ice cube machine begins with a xed charge of water that is contained in the water tank. As the water
ows to the freezing evaporator surface, the water will freeze and stick to the ice cube molds. During the
ice-making process, fresh water enters the water tank continuously as the water from the trough freezes
continuously on the evaporator.
NORMAL SOUNDS
Your new ice cube machine may make sounds that are unfamiliar to you. Most of the new sounds are
normal. Hard surfaces like the oor and walls can amplify the sounds. The following describes the kinds of
sounds that might be new to you and what may be causing them.
• Rattling noises may come from the ow of the refrigerant or the water line. Items stored on top of the ice
cube machine can also make noises.
• The high-efciency compressor may make a pulsating or high-pitched sound.
• Running water may make a splashing sound.
• You may hear air being forced over the condenser by the condenser fan.
• During the Harvest cycle, you may hear the sound of ice cubes falling into the ice storage bin.
PREPARING THE ICE CUBE MACHINE FOR LONG STORAGE
If the ice cube machine will not be used for a long time, or it is to be moved to another place, it will be
necessary to drain the system of water.
• Do not touch the power plug when your hands are wet.
• Never unplug the unit by pulling on the cord.

cleaning or use of sanitizing solution. Do not leave any solution inside the
ice maker after cleaning.
Periodic cleaning and proper maintenance will ensure efciency, top performance, and long life. The
maintenance intervals listed are based on normal conditions. You may want to shorten the intervals if
you have pets or there are other special considerations.
WHAT SHOULDN’T BE DONE
Never keep anything in the ice storage bin other than ice: objects like wine and beer bottles are not
only unsanitary, but the labels may slip off and plug up the drain.
WHAT SHOULD BE KEPT CLEAN
There are 4 things to keep clean:
1. The exterior
2. The interior
3. Water distribution tube
4. The ice-making system cleaning
Before proceeding with cleaning and maintenance operations, make
sure the power line of the unit is disconnected and the water line is shut
off. (EXCEPTION: Cleaning of ice-making system)
EXTERIOR CLEANING
The door and cabinet may be cleaned with a mild detergent and warm water solution such as 1 oz of
dishwashing liquid mixed with 2 gallons of warm water. Do not use solvent-based or abrasive cleaners.
Use a soft sponge and rinse with clean water. Wipe with a soft clean towel to prevent water spotting.
Clean stainless steel with a cloth dampened with a mild detergent and warm water solution. Never use
an abrasive cleaning agent.
INTERIOR CLEANING
The ice storage bin should be sanitized occasionally. Clean the water tank before the ice cube machine
is used for the rst time and reused after stopping for an extended period of time. It is usually convenient
to sanitize the trough after the ice-making system has been cleaned and the ice storage bin is empty.
1. Disconnect power to the unit.
3. Using a sanitizing solution made of 1 ounce of household bleach and 2 gallons of hot water (95º to
115ºF), wipe down the water tank and the inside of the ice storage bin with a clean cloth. To clean
hard-to-reach corners, apply the sanitizing solution with a spray bottle.
4. Rinse thoroughly with clear water. This completes the routine interior cleaning of the unit.
5. Reconnect the power.
The ice scoop should be washed regularly W
.ash it just like any other food container.

Cleaning and Maintenance
WATER DISTRIBUTION TUBE CLEANING
When you nd that the ice cubes are incompletely formed or the output of ice cubes is low, the water
distribution tube may be blocked. Turn off the machine. Unscrew the four screws holding the top panel
and remove the panel. You will see the water distribution tube. Rotate the water distribution tube so
that the holes in it are facing up. Using a toothpick or similar tool, dredge the holes, then rotate the
water distribution tube back to its original position. If the tube is badly blocked, clean it as follows:
1. Shut off the water and power supplies.
2. Disconnect the water hose from the distribution tube.
3. Gently take out the distribution tube.
4. With a brush, clean the tube with a dilute solution of warm water and a mild detergent such as
dishwashing liquid. After removing the dirt and lint from the surface, rinse the tube with clean water.
5. Replace the distribution tube.
6. Reconnect the water supply and power supply lines.
7. Re-attach the top panel.
ICE-MAKING SYSTEM CLEANING
Minerals that are removed from water during the freezing cycle will eventually form a hard, scaly
deposit in the water system. Cleaning the system regularly helps remove the mineral scale buildup. How
often you need to clean the system depends on how hard your water is or how effective your ltration
may be. With hard water of 15 to 20 grains/ gallon (4 to 5 grains/liter), you may need to clean the system
as often as every 3 months.
1. Press the ON/OFF button to turn off the machine.
2. Remove all ice cubes from the storage bin If ice is being made, initiate harvest or wait for cycle.
3. Keep the ice maker connected to the water supply. Pour 8 oz. of Nickel-Safe Ice Maker Cleaner
Solution into the water tank.
