HOW THE ICE MACHINES MAKES ICE
Turn the power switch to the ON position.
Then press ON/OFF button in front panel.
The LCD screen lights.
After about 3 minutes the machine will
automatically go into the ice-making stage.
There are two distinct cycles: freeze and harvest.
In the freeze cycle, water flows to the evaporator
surface. In the harvest cycle, the ice is released
and water enters the machine.
A complete cycle (freeze cycle and harvest cycle) takes 15 to 40 minutes,
depending on 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 pumping water. When the batch of ice has been fully formed, the ice maker stops
the
freeze cycle and the harvest cycle start.
Harvest: During the harvest cycle, the compressor is still operating and power is supplied to the hot gas
valve. Every 20 cycles, the water purge valve opens and allows the water pump to purge the water
from
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. The water pump will then stop. When the hot gas valve
opens, it allows
hot gas to go directly to the evaporator. The gas warms the evaporator, causing the
cubes to slide 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 maker begins with a fixed charge of water that is contained in the water tank. As the water flows
to
the freezing evaporator surface, the water freezes and sticks to the ice cube molds. During the ice-
making process, fresh water enters the water tank continuously as the water from the tank 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 floor 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 flow of the refrigerant or the water line. Items stored on top of
the ice
cube machine can also make noises.
The high-efficiency 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 or WHEN MOVING THE ICE MACHINE
1

Cleaning and Maintenance
Periodic cleaning and proper maintenance will ensure efficiency, 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
1 The exterior
2 The interior
3 Water distribution tube
4 The ice-making system cleaning
EXTERIOR CLEANING
The exterior of the ice maker and bin may be cleaned with a soft cloth or sponge dampened with a
mild detergent and warm water solution such as 1 oz of dishwashing liquid mixed with 2 gallons of warm
water. Never use solvent-based or abrasive cleaning agents. Rinse with clean water. Wipe with a
soft clean towel to prevent water spotting.
INTERIOR CLEANING
Clean the water tank before the ice maker is used for the first time and reused after stopping for an
extended period of time. It is usually convenient to sanitize the tank after the ice-making system
has been cleaned and the ice storage bin is empty. The ice storage bin should be sanitized
occasionally.
Follow these steps to clean the tank and the bin:
1. Disconnect power to the unit
2. Using a knifepoint or similar tool t o remove the plastic covers on the top and bottom front
panel
3. Using a Phillips screwdriver, remove the screws, then swing the front panel open
4. Using a sanitizing solution made o f 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.
5. Rinse thoroughly with clear water.
6. This completes the interior cleaning of the ice maker and storage bin.
7. Reconnect power to the unit.
CAUTION
If the ice maker is left unused for a long time, before the next use it must be thoroughly
cleaned Follow carefully any instructions provided for cleaning or use of sanitizing solution
Do not leave any solution inside the ice maker after cleaning.
WARNING
Before proceeding with cleaning and maintenance operations, make sure the power
line of the unit is disconnected and the water line is shot off. (EXCEPTION: Cleaning of ice-
making system)

Cleaning and Maintenance
WATER DISTRIBUTION TUBE CLEANING
When you find that the ice cubes are incompletely formed or the output of ice cubes is low, the water
distribution tube may be blocked Set the power switch to OFF Unscrew the six 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. Lift one side, remove 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 and front panels
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
filtration 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. Using tools to remove the plastic c over and screws fixed in front panel, swing the front panel
open.
2. Make sure all ice is off evaporator If ice is being made, initiate harvest or wait for cycle
completion, then turn machine off at the power switch.
3. Remove all ice cubes from the storage bin.
4. Keep the ice maker connected to the water supply Pour 8 oz of Nickel-Safe Ice Maker
Cleaner Solution into the water tank.
5. Press ON/OFF button to light the LCD screen. Within 3 minutes, press the CLEAN button.
The machine will automatically shift into cleaning mode.
6. The ice-making system cleaning cycle will continue for 30 minutes unless you press ON/OFF
button (you can press the power switch to stop the cleaning cycle any time during the 30
minutes) After cleaning, the LCD screen will display the words of "OFF"
The cleaning
process stops.
7.
Repeat steps 4 and 5 above, three times, to rinse the ice machine thoroughly.
(NOTE: Do not add Ice Maker Cleaner Solution to the water tank during the rinses.)
8. Perform steps 3 and 4 in the Interior Cleaning section.
9. If you want to make ice cubes after cleaning, turn off the power switch, then turn on the
power switch The next ice-making cycle will begin.
10. Discard the first batch of ice.
WARNING
DO NOT use solvent-based cleaning agents or abrasives on the interior These cleaners
may transmit taste to the ice cubes, or damage or discolor the interior

CONDENSER CLEANING
1 See drawing
2 The air cooled condenser should be
vacuumed once or twice per year to
remove any lint that may have been
drawn into it Using a tool that seems
like a probe to remove any lint from
the condenser fins.
NOTE: Do not touch condenser fins. They are
sharp and can be damaged easily.
