Electrical Requirements

10
Before you move your ice maker into its final location, it is important to make sure you have the
proper electrical connection. A standard electrical supply (120VAC only, 60Hz, 15A), properly
grounded in accordance with the National Electrical Code and local codes and ordinances, is
required. The ice maker should always be plugged into its own individual electrical outlet. It is
recommended that a separate circuit, serving only your ice maker, be provided. Use receptacles
that cannot be turned off by a switch or pull chain. The fuse (or circuit breaker) size should be 15
amperes.
Recommended grounding method
For your personal safety, this appliance must be grounded. It is equipped with a power supply
cord having a 3-prong grounding plug. To minimize possible shock hazard, the cord must be
plugged into a mating 3-pronged and 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 grounded,
3-prong wall receptacle installed by a qualified electrician.
Leveling the Ice Maker
Once the ice cube machine is set in its enclosure, if the base is not level, you can adjust the feet
by rotating the under block (see below) until the machine is level.
It is important for the ice maker to be leveled, or water may not flow properly through the
evaporator (ice mold). Ice production will be lower than normal, and operation will be noisy.
Adjust the height of the under block of the adjustable foot, rotating it to the right (counter-
clockwise) to lower that side of the ice maker. Turning the under block to the left (clockwise)
raises that side of the ice maker.
Water Supply
The water supply should be ready at the point of installation. The water supply pressure should
be a minimum of 15 psig with a static pressure not more than 80 psig. (A wall outlet directly
behind the ice maker will make installation easier.)
We strongly recommended the use of a water filter. A filter, if it is of the proper type, can remove
taste and odors as well as particles and can prolong the life of the machine .

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.

13
Evaporator
•Never turn the water supply tap off when the ice maker is working.
•Never touch the evaporator when the machine is running.
•Except to take ice from the unit, keep the door closed to reduce melting and insure proper ice
formation.
How the Machine Makes Ice
When the power switch is first turned ON, the machine is in Stand-by mode. After about 3
minutes, it will automatically proceed to 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 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, 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 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 fixed charge of water that is contained in the water tank. As
the water flows 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 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
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.
1. Shut off the water supply at the main water source.
2. Disconnect the water supply line from the water inlet.
3. Shut off the power supply at the main electrical power source.
4. Screw off the water tank screw nut and drain out water completely, then tighten the nut after
finishing. Dry the tank.
5. Remove the ice from the ice storage bin. Dry the bin.
6. Leave the door open to allow for circulation and to prevent mold and mildew.
7. Leave the water supply line and power cord disconnected until ready to reuse.
IMPORTANT:
• Do not touch the power plug when your hands are wet.
• Never unplug the unit by pulling on the cord.
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?
There are 4 things to keep clean:
1. The exterior
2. The interior
3. Water distribution tube
4. The ice-making system

15
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 first 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.
2. Open the door. You will find the water tank screw nut on the front right of the water tank.
Screw off the nut and drain water completely into the ice storage bin. The water drains out of
the machine through the drain hole in the bin.
NOTE: Don’t forget to screw the nut back into place 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 routine interior cleaning of the unit.
5. Reconnect the power.

16
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 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 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. Set the power switch to OFF.
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 Maker
Cleaner Solution into the water tank.
4. Turn the power switch ON. Within 3 minutes, press the CLEAN button. The machine will
run the Automatic Clean mode. The green Ice Making and the yellow Ice Harvest LEDs will
blink.
5. The 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 green Ice Making and yellow Ice Harvest LEDs go on steady and the machine
returns to Stand-by mode.
6. The dirty water must be drained out completely. Perform steps 2 and 3 in the Interior
Cleaning section.
7. Repeat steps 1 to 6 above three times to rinse the ice-making system completely.
NOTE: Do not add Ice Maker Cleaner Solution to the water trough 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.

17
Sanitizing the Ice-Making System
1. Set the power switch to OFF.
2. Remove all ice cubes from the storage bin.
3. Prepare a sanitizing solution by mixing 1 oz. household bleach with 1 gallon of warm water.
4. Keep the ice maker connected to the water supply. Fill the water tank with the sanitizing
solution.
5. Turn the power switch ON. Within 3 minutes, press the CLEAN button. The machine will run
the Automatic Clean mode. The yellow Ice Harvest and the red Bin Full LEDs will blink.
6. The cleaning cycle will continue for 30 minutes unless you press the power switch (you can

Thinner ice bridge setting:
By pressing the “Clean” button, you can decrease the size of the ice bridge. The “ICE FULL” LED
(white) will flash as you lower the ice bridge thickness and will finally be blinking at the setting of
thinnest ice bridge.
Thicker ice bridge setting:
By pressing the “Mode” button, you can increase the thickness of the ice bridge. The “ICE
HARVEST” LED (yellow) will flash as the larger thickness is set and will blink when the setting of
thickest ice bridge has been reached.
After 10 seconds without any operation, the unit will automatically memorize the current state and
return to the previous (Ice Making) mode.
NOTE: If during the ice bridge adjustment, the “ICE FULL”, “ICE MAKING” and “ICE
HARVEST” LEDS blink all at once, this indicates that the unit is in the default factory setting of the
ice bridge adjustment.
IMPORTANT: The ice bridge adjustment has been set at the factory for optimum performance and it
is not recommended for a user to make this adjustment. This ice adjustment procedure should
therefore be made only by an authorized service technician
