Before you plug the ice maker in to a power supply, be sure to let it
stand upright for at least 24 hours to allow the compressor’s oils to
settle.
Unpacking the Ice Maker
WARNING: Use two more people to move and install the ice maker.
Failure to do so can result in back or other injury.
Carefully remove the packaging materials. Remove any shipping tape
and glue from your ice maker before using. Do not use sharp
instruments, rubbing alcohol, flammable fluids, or abrasive cleaners to
remove tape or glue. These products can damage the surface of your
icemaker. IMPORTANT: Do not remove any safety, warning, or product
information labels from your ice maker.
Types of Installation
This ice maker has been designed for free-standing, recessed, or built-
in installation. In every case, there must be adequate ventilation and
access for service.
Free-standing installation:
A free-standing installation will allow you to install the icemaker in any
place you desire provided you have access to a water supply and a
drain. You must follow the stated instructions for electrical
requirements, water supply and drain, and leveling the icemaker.
Recessed installation:
A recessed installation will allow you to install the ice maker under a
counter or in a kitchen cabinet provided the required clearance
space around the ice maker is followed. This installation has the same
requirements as a built-in installation.
Built-in installation:
It is necessary to allow adequate ventilation space around the unit
(make sure there is at least some ventilation room for the back of the
unit). The following additional items must be observed.
1. Place the ice maker in front of the installation location. Remove
the feet and place the unit flat on the floor or on a platform
depending on your installation requirements.
2. The water supply pipe must be plumbed before connecting to the
ice maker. Install the drain line into your drain.
3. Turn on main water supply and tap. Check for water supply
connection leaks. Tighten any connections (including connections
at the tie-in).
4. If the electrical outlet for the ice maker is behind the cabinet, plug
in the ice maker.
5. Push the ice maker into position.
6. Seal all around the cabinet to the floor with an approved caulking

Electrical Requirements
Before you move your icemaker into its final location, it is important to
make sure you have the proper electrical connection:
A standard electrical supply (115 V, 60Hz.), properly grounded in
accordance with the National Electrical Code and local codes and
ordinances, is required.
It is recommended that a separate circuit, serving only your icemaker,
be provided. Use receptacles that cannot be turned off by a switch or
pull chain.
The fuse (or circuit breaker) size should be 3 amps.
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.
Electrical Shock Hazard
Plug into a grounded 3-prong outlet.
Never remove the grounding prong from the plug.
Never use an adapter.
Never use an extension cord.
Failure to follow these instructions can result in fire,
electrical shock, or death

Installation of Casters
]Important: Use at least two or more people to properly install casters.
Carefully have one person tilt the unit away from them while the other
person helps to support it. Make sure to give yourself enough
clearance to insert the caster and tightly screw in clockwise. Please
follow the diagram pictured below.
Leveling the Ice Maker
It is important for the icemaker to be leveled in order to work properly.
It can be raised or lowered by rotating the plastic sheaths around
each of the four feet on the bottom of the machine .If you find that
the surface is not level, rotate the feet until the ice maker becomes
level .You may need to make several adjustments to
level it. We recommend using a carpenter’s level to check the
machine.
1. Place a carpenter’s level on top of the product to see if the ice
maker is level from front to back and side to side .
2. Adjust the height of the feet as follows:
Turn the leveling feet to the right to lower that side of the ice maker
Turn the leveling feet to the left to raise that side of the ice maker .
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. If the floor is
level, just revolve the two front feet to touch the floor.

7
Reversing the Door Swing
Tools needed: flathead screwdriver, Phillips screwdriver
IMPORTANT: Before you begin, unplug the ice maker or disconnect
power.
To remove door from hinges:
1. Using a Phillips screwdriver, remove the screws and take off top
hinge. Keep the parts together and set them aside.
3. Lift door off bottom hinge and turn it upside down so that the
handle is on the right. Set door aside.
To replace door on hinges:
1. Using a flathead screwdriver, remove the plug buttons from the
screw holes opposite the door hinges, top and bottom. Set aside.
2. Remove the bottom hinge, place on the opposite side at the
bottom of the door.
3. Position the door on the bottom hinge.
4. Align the door on the bottom hinge and replace the top hinge.
5. Push the plug buttons into the original screw holes.

EdgeStar Built-in Ice Maker 8
Water Supply Connections
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.)
IMPORTANT:
1. All installations must be in accordance with local plumbing code
requirements.
2. Make certain that the pipes are not pinched or kinked or
damaged during installation.
3. Check for leaks after connection.
Tools required: ½ in. open-end wrench, Phillips screwdriver
Connecting the water line:
1. Turn off main water supply. Turn on nearest faucet long enough to
clear line of water.2. Find a ½ in. to ¾ in. vertical cold water pipe near
the installation location. The distance should be less than 9 feet. The
water supply hose provided with the ice maker is about 9 feet long.
3. A shut-off valve must be installed to the main water supply. If the
water pipe has a plain piece of copper tubing, attach a ¼” O.D.
compression union to the tubing and remove the nut.
4. Connect nuts of the water supply hose to tap and water inlet valve.
Tighten firmly by hand, then one-half turn with wrench.
5. Turn on main water supply and tap. Check for water supply
connection leaks. Tighten every connection (including connections at
the water inlet).
IMPORTANT:When you connect the water supply hose, pay attention
to the indications of “Water inlet” on the machine.
• In general, it is always a good idea to filter the water. A water filter
can remove taste and odors as well as particles. Where water is very
hard, softened water may result in white, mushy cubes that stick
together. Deionized water is not recommended.
Drain
NOTE: There is a drain line on the ice maker. Please drain water to your
drain through the drain line provided with ice maker.
1. Locate the floor drain near the ice maker. The distance should be
less than 4.5 feet since the length of the long drain hose provided with
the ice maker is about 4.5 feet.
2. Find the drain hose on the back of ice maker, then insert the other
side of the hose into the drain line.
All horizontal runs of drain lines must have a fall of 1/4” per foot. An air
gap will likely be required between the ice maker drain hose and the
drain/waste receptacle. A stand pipe with a trap below it would be
acceptable for the drain/waste receptacle. A floor drain is also
acceptable.
4. Pour 1 gallon of water into the ice storage bin to check for proper
drainage.
Note: a condensate pump can allow for installation further from your
drain. Consult your plumber for advice.

Operating Method
1. Turn on the water tap, let the water trough fill, and then switch the
ICE/OFF/WASH switch on the front panel to the ICE position. The ice
maker will start working automatically.
2. After three minutes, the machine will automatically go to the ice
making stage, and the sound of flowing water will be heard.
3. When the batch of ice has been fully formed, ice will automatically
be harvested to the ice storage bin.
4. When the ice storage bin is full, the sheet of cubes will not fall
completely and will hold the ice-full probe open. The machine stops
making ice and automatically.
5. The unit will start making ice again after the ice cubes are
removed. At that time, the ice-full probe swings back to operating
position.

EdgeStar Built-in Ice Maker 10
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 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
Turn the ICE/OFF/WASH switch to the ICE position. The machine will
automatically start 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 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 have been
harvested.
How the machine uses the water
The ice maker begins with a fixed charge of water that is contained in
the water trough. As the water flows to 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 trough. During the ice-making process,
fresh water enters the water trough continuously as the water from the
trough freezes continuously on the evaporator.

Normal Sounds
Your new icemaker may make sounds that are not familiar to you.
Most of the new sounds are normal. Hard surfaces like the floor, walls
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.
xRatting noises may come from the flow of the refrigerant or the
water line, Items stored on top of the icemaker can also make
noises.
xThe high efficiency compressor may make a pulsating or high-
pitched sound.
xWater running from the evaporator to the water bin may make
a splashing sound.
xAs each cycle ends, you may hear a gurgling sound due to the
refrigerant flowing in your icemaker.
xYou may hear air being forced over the condenser by the
condenser fan.
xDuring the harvest cycle, you may hear the of ice cubes falling
into the ice storing bin.
Preparing the Icemaker 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 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 electric supply at the main electrical power source.
4. Take out the ice storage bin to remove ice and water. Dry it.
6. Pull off the drainage tube of the water trough to drain off all water.
7. Leave the door open to allow for circulation and to prevent mold
and mildew.
8. 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 plug.

EdgeStar Built-in Ice Maker 12
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.
Note: Never keep anything in the ice storage bin that is not ice:
objects like wine or beer bottles are not only unsanitary, but the labels
may slip off and plug up the drain.
What should be kept clean
There are 5 things to keep clean:
1. The exterior.
2. The interior.
3. The condenser
4. Water distribution tube
5. The 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. If the door panel is
stainless finish, it can discolor when exposed to chlorine gas and
moisture. Clean stainless finish with a cloth dampened with a mild
detergent and warm water solution. Never use an abrasive
cleaning agent.
The icemaker must be thoroughly cleaned if it has been
left unused for a long time. Follow carefully any
instructions provided for cleaning or use of sanitizing
solution. Do not leave any solution inside the icemaker
after cleaning.

13
Interior Cleaning
The ice storage bin should be sanitized occasionally. Clean the water
trough 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 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 and take out the removable storage bin. With a clean
cloth, wipe down the interior of the unit with a sanitizing solution made of
1 ounce of household bleach and 2 gallons of hot water (95º to 115ºF).
3. Rinse thoroughly with clean water.
4. Put the cleaned and empty ice storage bin back inside the unit.
5. Reconnect power to the unit.
The ice scoop should be washed regularly. Wash it just like any other
utensil.
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 six months.
1. Unplug the ice maker or disconnect power.
2. Remove the 2 screws at the bottom of the front cover and gently pull it
off.
3. Locate the condenser directly behind the front cover.
4. Remove dirt and lint from the condenser and the unit compartment
with a brush attachment on a vacuum cleaner.
5. Reattach the front cover.
6. Plug in the icemaker or reconnect power.
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.
DO NOT touch the condenser. They are sharp and can be damaged
easily.

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 ICE/OFF/WASH switch to OFF, rotate the water distribution tube,
and locate the holes in the distribution tube. 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 supply.
2. Disconnect the water hose from the distribution tube.
3. Lift the right side, and then 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
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
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 as
often as every 6 months.
1. Make sure that all the ice is off of the evaporator. If ice is being
made, wait for cycle completion, then turn the machine “OFF” at
the ICE/OFF/WASH selector switch.
2. Remove all ice from the storage bin .
3. Keep the ice maker connected to the water supply , Pour 200g. of
Nickel-Safe Ice Maker Cleaner Solution into the water trough. After
about 5 minutes, initiate the wash cycle at the ICE/OFF/WASH
selector switch by the switch in the “WASH ”position. The machine
will run the Automatic Clean Mode.
4. Allow 30 minutes for proper cleaning. After cleaning, turn the
machine “OFF” at the ICE/OFF/WASH selector switch, Drain off the
waste water to some container by drain pipe in the left of the
water trough.
5. Repeat steps 3 and 4 (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.
6. Prepare a sanitizing solution made of 1 ounce of household bleach
and 2 gallons of hot water (95º to 115º F). Wipe the entire bin inside
and out, covering every wall surface.
7. Fill a spray bottle with the sanitizing solution and spray all corners
and edges making sure to cover all surfaces with the solution.
8. Allow the solution to be in contact for at least 3 minutes, then dry.
9. Repeat step 5 to rinse the ice making system one more time.
10. Place the ICE/OFF/WASH selector switch to the “ICE ” position. The
machine will return to the regular ice making mode. Discard the
first batch of ice.
• Many ice machine cleaners
contain acids.
• DO NOT use or mix with any
other solvent-based cleaner
products.
