13
Ice-making stage Ice harvest stage
IMPORTANT:
?Although the unit has been tested and cleaned at the factory, due to long-term transit
and storage, the first batch of cubes must be discarded.
?Never turn off the water supply tap when the ice maker is working.
?Never touch the evaporator when the machine is running.
?Except to take ice from the unit, keep the bin door closed to reduce melting and ensure
proper ice formation.
How the Machine Makes Ice
Turn the power switch to the ON position. After about 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 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) takes15 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
starts.
Harvest: During the harvest cycle the compressor is still operating, but the water pump
has stopped. The hot gas valve opens, diverting hot refrigerant gas into 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 freezesand sticksto 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.

14
Normal Sounds
Your new ice maker 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
storedon the top of the ice maker 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 Maker for Long Storage
If the ice maker will not be used for a long time, or it is to be moved to another place, it
will be necessary to drain water from the system.
1. Shut off the water supply at the main water source.
2. Disconnect the water supply pipe from the water inlet.
3. Shut off the power supply at the main electrical power source.
4. Screw off the water tank’sdrain screw nut and drain out water completely, then
tighten the nut after finishing. Dry the water tank.
5. Remove all ice cubes from the ice storage bin and dry it.
6. Leave the door open to allow for ventilation and to prevent mold and mildew.
7. Leave the water supply pipe and power cord disconnected until ready to reuse.

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 unsanitary, and the labels may slip off and block the drain.
What should be kept clean?
There are 5 things to keep clean:
1. The exterior
2. The interior
3. Water distribution tube
4. The ice-making system
5. Condenser air filter
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:

16
1. Disconnect power to the unit.
2. Remove the front panel of the ice maker. Unscrew the water tank screw nut and drain
water completely into the ice storage bin.The water drainsout through the drain hole
in the bin. (NOTE: Don’t forget to screw the nut back into the water tank hole again.)
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 interior cleaning of the ice
maker and storage bin.
5. Reconnect power to the unit.
The ice scoop should be washed regularly. Wash it just like any other food container.
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 top and front panels.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 and 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/gal. (4 to 5 grains/liter), you may need to clean the system every 3 months.
1. Whether the machine is in ice-making or harvest stage, turn off the power switch.
2. Remove all ice cubes from the storage bin.
3. Keep the ice maker connected to the water supply. Pour 8 oz. of Nickel-Safe Ice

17
Maker Cleaner Solution into the water tank.
4. Turn on the power switch.Within 3 minutes press the Clean button. The machine will
go into the cleaning mode automatically.
5. The ice-making system cleaning cycle will continue for 30 minutes unless you press
the power switch (you can press the power switch to stop the cleaning cycle any time
during the 30 minutes). After cleaning, the harvest indicator and ice-making indicator
LEDs will be on. The cleaning process stops.
(NOTE: The dirty water must be drained out completely.)
6. Perform steps 2 and 3 in the Interior Cleaning section.
7. Repeat steps 3 to 5above three times to rinse the ice-making system thoroughly.This
will complete ice-making system cleaning.
(NOTE: Do not add Ice Maker Cleaner Solution to the water tank during the rinses.)
8. If you want to make ice cubes after cleaning, turn off the power switch, drain off the
waste water, then turn on the power switch. The next ice-making cycle will begin.
9. Discard the first batch of ice.
Condenser Air Filter Cleaning
1. Remove the screwsand pins holding the condenser air filter.See drawing below.
Condenser air filter

18
2. Remove the condenser air filter with a screwdriver.
3. Use a brush to wipe up and down the filter surface with a mild detergent solution such
as 1 oz.of dishwashing liquid mixed with 2 gallons of warm water. Do not use
solvent-based or abrasive cleaners. Rinse the filter with clean water several times.
4. Air-dry the filter, then reinstall it.
Control Panel (at the back of the machine)
You will find the control panel at the back of the machine.This panel includes one
button,one adjustable screw and four indicator LEDs.
Operation of the control panel:
1. When the unit is plugged in and the power switch is turned on, the power indicator and
the other three indicator lights are all on.
2. After three minutes for water inlet, the ice maker will start to make ice automatically.
Only the power and ice-making indicators will be on.
3. During harvest, the harvest indicator light is on and ice-making indicator off. When
the ice storage bin is full, only the ice-full indicator and power indicator are on.
4. If the Clean button is pressed during the ice-making mode, it will be ignored. The
ice-making will continue.

5. When you want to clean the machine, turn off the power switch first, then turn it on
again.Press the Clean button within 3 minutes and the ice maker will start the
cleaning mode,with harvest and ice-making indicators blinking. After 30 minutes, the
cleaning mode stops and the harvest indicator and ice-making indicators are on steady.
If you want to restart the ice-making process after cleaning, turn off the power switch
first and drain off the waste water, then turn on the power switch again and the
machine will automatically go into the ice-making process.
6. If you want to interrupt the cleaning mode before it is finished, do not press the Clean
button again. Instead, turn the power switch off. This stops the cleaning cycle.
7. If the machine is on but only the power indicator light is lit, this may indicate that not
enough water is reaching the system, that the water pump is not functioning, or some
similar problem. First check the level in the water tank, then examine the water pump,
etc.
8. If the unit is connected to the power supply but no visual indicator lights up when the
power switch is turned on, the fuse in the control panel box may need to be replaced.
Descriptions of LEDs and buttons:
1. Ice Full (white) LED: Ice Full indicator light
