equipped with a power supply cord having a grounding plug. To minimize
possible shock hazard, the cord must be plugged into a mating grounding-type
wall receptacle, grounded in accordance with the National Electrical Code and
local codes and ordinances. If a mating wall receptacle is not available, it is the
personal responsibility of the customer to have a properly grounding wall
receptacle installed by a qualified electrician.
Leveling the Ice Maker
It is important for the ice maker to be leveled in order to work properly. You may
need to make several adjustments to level it.
This type of ice maker has a combination of four feet/rollers on the bottom. It can
be easily moved anywhere by one person. You will find the feet/rollers
combinations very useful for cleaning and sanitizing the surface on which the ice
maker is installed because it allows you to move the unit and have easy access to
the surface to be cleaned.
IMPORTANT: Once you are ready to install it in a cabinet or directly on the floor,
you must adjust the feet to level the ice maker and lock the rollers. If the floor is
level, just revolve the two front feet to touch the floor. (See illustration.)

Operating Method
1. Switch on the Power switch on the
front panel. The light will be on. The
ice maker will start working
automatically and feeding water.
2. After the first feeding of the water,
the machine will automatically go to
the ice making stage, and the sound
of water spraying will be heard.
3. Ice will be harvested to the ice
storage bin. When the storage bin is
filled with ice cubes, the ice maker
will automatically stop working. The
machine will restart making ice once
the storage bin is less than full.
4. Excess water will flow through the
drain oulet at the back of the machine and empty into the floor drain.
IMPORTANT:
- Although the unit has been tested at factory, due to long-term transit and storage,
the first batch of cubes must be discarded.
- Never turn the water supply tap off when the icemaker is working.
How the Machine Makes Ice
There are two distinct cycles: freezing and harvest.
During the freezing cycle, water is sprayed against the evaporator surface.
In the harvest cycle, the ice is released and water enters the machine. A complete
cycle takes about 20 minutes.
Freeze: During the freezing cycle the compressor is pumping refrigerant, the fan
motor is blowing air, and the water pump is circulating water. When the
evaporator surface gets to the setting temperature, the ice maker stops the freezing
cycle and begins the harvest.
Harvest: During the harvest cycle the compressor is still operating, but the water
pump has stopped. Two other components have been energized: the hot gas valve
15
Page 17
and water inlet valve. These two valves open and warm up the freezing surface, so
the cubes to fall into the bin. The freeze cycle will restart.
How the machine uses water
The ice maker begins
with a fixed charge of
water that is contained
in the water bin. As
the water is sprayed
against the freezing
evaporator surface,
the portion of water
that does not contain
mineral impurities
will freeze and stick
to the ice cube molds.
The water containing
impurities falls back into the water bin. Gradually, during the freezing portion of
the ice-making cycle, the water in the water bin will become highly concentrated
with mineral impurities.
During the harvest cycle, the fresh water flows into the machine to dilute the bin
water, and to rinse the concentrated minerals down the drain.
Normal Sounds
Your new ice maker may make sounds that are not familiar to you. Most of the
new sounds are normal. Hard surfaces like the floor, walls and cabinets can make
the sounds seem louder than they actually are. The following describes the kinds
of sounds that might be new to you and what may be making them.
• You will hear a swooshing sound when the water valve opens to fill the water
bin for each cycle.
• Rattling noises may come from the flow of the refrigerant or the water line.
Items stored on top of the ice maker can also make noises.
• The high-efficiency compressor may make a pulsating or high-pitched sound.
• Water running from the water bin to the evaporator plate may make a
splashing sound.
16
Page 18
• Water running from the evaporator to the water bin may make a splashing
sound.
• As each cycle ends, you may hear a gurgling sound due to the refrigerant
flowing in your icemaker.
• 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.
• When you first start the ice maker, you may hear water running continuously.
The ice maker is programmed to run a rinse cycle before it begins to make ice.
Preparing the Ice Maker for Long Storage
If the ice maker will not be used for a long time, or is to be moved to another
place, it will be necessary to drain the water of system.
1. Shut off the water supply at the main water source.
2. Disconnect the water supply line from the water inlet valve.
3. Disconnect the drain pipe to the drain line or floor drain.
4. Allow the ice maker to run for an hour or more until all remaining ice cubes
have been ejected from the ice maker assembly.
5. Shut off the electric supply at main electrical power source.
6. Screw off the nut of the water drain hole at the back of the machine, drain out
water residue completely (do not loosen or screw off the nut at other times),
then tighten the nut after finishing.
7. Drop the door open to allow for circulation and prevent mold and mildew.
8. Leave water supply line and power cord disconnected until ready to reuse.
CLEANING AND MAINTENANCE
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.
17
Page 19
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 the unit is used
outdoors, or there are other special considerations.
What shouldn't be done
Never keep anything in the ice storage bin that is not 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 condenser
3. The interior
4. The ice-making system
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: Ice maker system’s cleaning).
Exterior Cleaning
The door and cabinet may be cleaned with a mild detergent and warm water
solution such as 28g of dishwashing liquid mixed with 7.5L 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.
Stainless steel models can discolor when exposed to chlorine gas and should be
cleaned. Clean stainless steel models with a mild detergent and warm water
solution and a damp cloth. Never use abrasive cleaning agents.
NOTICE: Stainless steel models exposed to chlorine gas and moisture, such as in
areas with spas or swimming pools, may have some discoloration of stainless
steel. Discoloration from chlorine gas is normal.
18
Page 20
Condenser Cleaning
A dirty or clogged condenser prevents proper airflow, reduces ice making capacity,
and causes higher than recommended operating temperatures that may lead to
component failure. Have the condenser cleaned at least once every three months.
1.Unplug the ice maker or disconnect power.
2. Remove the 2 screws in the front cover. Pull upward to remove the front cover.
3.Locate the condenser surface.
4.Remove dirt and lint from the
condenser fins and the unit
compartment with a brush attachment
on a vacuum cleaner.
5.Reassemble the front cover.
6.Plug in the icemaker or reconnect
power.
DO NOT touch the conderser fins. The condenser fins are sharp and can be
easily damaged.
Interior Cleaning
The ice storage bin should be sanitized occasionally. Clean the bin 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 bin after the ice making system has
been cleaned, and the storage bin is empty.
1. Disconnect power to the unit.
2. Open the door and with a clean cloth, wipe down the interior with a
sanitizing solution made of 28g of household bleach or chlorine and 7.5L of
hot water (35℃ to 46℃).
3. Rinse thoroughly with clear water. The waste water will be drained off
through the drainpipe.
4. Reconnect power to the unit.
The ice scoop should be washed regularly. Wash it just like any other food
container.
19
Page 21
IMPORTANT NOTE: The sprinkler should only be cleaned when you find that
some of the ice cubes are improperly shaped during ice making. Cleaning the ice
making system should follow cleaning of the sprinkler.
1. Connect power to the unit and open the door.
2. Take out the row of flake covers.
3. Find the sprinkler and the slideway.
20
Page 22
4. Open the power switch, the ice maker works. Water sprays from the small
nozzles, find which water sector is not sprayed well. If the reason is the
slideway break the water sector, just adjust the position of slideway to have all
the water sectors free forward to the ice mold. If the water sectors are free, but
some sector is not sprayed well, using a new teeth-brush clean the gap of the
nozzle several times. The water sector will be OK.
5. This kind of cleaning method can’t change the cubes quality (only the ice
cube’s shape), you can do another cleaning method. Remove the slideway
from the water bin.
6. Find the sprinkler arm and raise it. Disconnect it from any water tube.
21
Page 23
7. A de-scaling solution can be prepared in a plastic basin with Nu-Calgon
Nickel-Safe Ice Machine Cleaner. Mix 4 ounces of the ice machine cleaner per
gallon of warm water.
8. Remove the sprinkler arm from the interior. Thoroughly clean the sprinkler
arm by soaking it in the basin filled with the de-scaling solution until it is free
of any deposit; use a soft brush to remove any thick or stubborn residue and to
help the dissolving action. Rinse under a stream of tap water.
9. Wipe down the interior of the water bin with the de-scaling solution and warm
water. Rinse thoroughly with clear water.
10. Reassembly properly the sprinkler arm, slideway and the flake covers.
11. After the Icemaker System Cleaning procedure below.
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 upon how hard your water is. With hard water of 4 to 5 grains/liter, you
may need to clean the system as often as every 6 months.
1. Turn off power to the ice maker. Keep the ice maker connecte to the water
supply and drainpipe.
2. Open the door and scoop out all of the ice cubes. Either discard them or
22
Page 24
save them in an ice chest or cooler.
Remove the screws in the front cover, push forward to remove the front cover.
Notice: Don’ t overexert, or the leads connected with the power switch can be
torn down. Put the front cover against the right side cover.
3. Locate the control box.
4. Turn on the power to the
ice maker. Pour 230g of
Nickel-Safe Ice Maker
Cleaning Solution into
the water bin. Add 230g
of tap water. After about
5 minutes, press down
the "clean" button on the
Water bin
Control Box. (See figure
below and following
section.) The machine will run the
Automatic Clean Mode.
5. Allow 30 minutes for proper cleaning. After
cleaning, shut off the power switch, and
unscrew the nut of the water-draining hole.
Drain off the waste water to some container,
and then screw the nut on tightly when the
waste water is fully drained off.
6. Repeat steps 4 and 5 (without Ice Maker
Cleaning Solution) to rinse the ice making
system 3 times.
Note: The use of the Ice Maker Cleaner Solution in the water bin during
the rinse is not needed.
The ice machine cleaner contains acids.
DO NOT use or mix with any other solvent-based cleaner products.
Use rubber gloves to protect hands. Carefully read the material safety
instructions on the container of the ice machine cleaner.
DISCARD the first batch of ice troduced after cleaning.
7. Prepare a sanitizing solution made of 28g of household bleach and 7.5L of
hot water (35
℃ to 46℃). Remove the flake covers and slideway from the
water bin and wipe the entire bin inside and out, covering the entire
surface of the walls.

8. Fill a spray bottle with the sanitizing solution and spray all corners and
ll
edges making sure to cover all surfaces with the solution. Soak the flake
cover and slideway in the solution and put back in place after drying.
9. Allow the solution to be in contact for at least 3 minutes, then dry.
10. Repeat step 6 to rinse the ice making system one more time.
11. Reassemble the front cover.
12. Turn on the power again. The machine will return to the regular ice
making mode. Discard the first batch of ice.

Descriptions of LEDs and buttons:
1. RED LED: Ice full indicator light.
When this LED is lit, the ice storage bin is full of ice or there is something
between the two arms of the ice-full sensor in the ice storage bin. The unit will
stop working. When ice cubes are taken out of the ice storage bin, clearing the
sensor, the red LED will keep flashing for 3 minutes. Then the unit will
restart and return to the ice making mode.
2. GREEN LED: Ice making indicator light.
When this LED is lit, the unit is working in the ice making mode controlled by
a temperature probe on the evaporator. When the green LED is flashing, the
unit is working in the ice making mode controlled by a fixed timer.
3. YELLOW LED: Ice harvest indicator light.
When this LED is lit, the unit is working in the ice harvest mode controlled by
a temperature probe on the evaporator. When the yellow LED is flashing,
the unit is working in the ice harvest mode controlled by a fixed timer.
4. CLEAN button: When this button is pressed, the unit enters the cleaning
mode. The green and yellow LEDs flash together. To stop the cleaning mode,
just press the button again.
5. MODE button: Mainly for service. When this button is pressed, it can change
from ice making mode to ice harvest mode, or from ice harvest mode to ice
making mode. You can judge the mode from the status of the green and yellow
LEDs.
6. ICE SIZE ADJUST: Turn the screw clockwise, and the size of individual ice
cubes will be larger in the next cycle; the cycle time will be longer. Turn the
knob counter-clockwise, and the ice size will be smaller in the next cycle.
NOTE: It is not a good idea to adjust the ice size often or for no good reason,
because the controller may damaged.
7. If the red, green and yellow LEDs are flashing together, the machine is not
working. The major fuse of the control box has failed. Call for service.
NOTE: Avoid letting water contact the control box.

Major Functions
1. Completely automatic operating procedure.
2. When the ice storage bin is full of ice cubes, the machine stops working
automatically and starts again after the cubes are removed.
3. The different colors of the LED display indicate various work modes.
4. Indication of failure of major control box fuse.
5. The fan motor responds to the ambient temperature. If it is cold, the motor
will stop working to keep the cooling system in good working condition.
6. Ice cube size is adjustable.
7. A sensitive probe and accurate timer enhance the performance of the ice
maker.
8. Manual clean mode to start or stop the ice making system cleaning.
9. Built-in compressor protection system.
