Installing the Ice Maker  
The ice maker should be installed by a licensed plumber to be in accordance with  
local electrical and plumbing code requirements.  
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.

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  
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.

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.

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.

OPERATION  
Final Check List before Operation  
1. Have all packing materials and tape been removed from the interior  
and exterior of the ice maker?  
2. Did you clean the ice storage bin?  
3. Have the installation instructions been followed, including connecting  
the machine to water and electricity? Does the unit have proper  
drainage?  
4. Has the machine been leveled?  
5. Is the ice maker in a site where the ambient temperature is between  
50º F and 100ºF and the water temperature between 41º F and 90º F all  
year round?  
6. Has the water supply pressure been checked to ensure a minimum of  
15 psig with a static pressure not to exceed 80 psig?  
7. Is there a clearance of at least 2/5” at the rear, 1” at the top and 1/5” at  
the sides for proper air circulation?  
8. Has the power supply voltage been checked or tested against the  
nameplate rating? And has proper grounding been installed for the ice  
maker?  
9. Is the ice maker plugged in?  
10. Have you turned on the main water supply and the tap?  
11. Have you checked for leaks at all water supply connections- and at  
the drain?  
Operating Method  
1. Turn on the water tap, let the water trough fill, 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 progresses to the cold preservation stage.  
During this stage, the compressor works regularly to keep the  
temperature lower to reduce ice melting.  
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.

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.  
Ratting noises may come from the flow of the refrigerant or the  
water line, Items stored on top of the icemaker can also make  
noises.  
The high efficiency compressor may make a pulsating or high-  
pitched sound.  
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 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.

CLEANING AND MAINTENANCE  
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.  
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.

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.  
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  
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 filter. This can be lifted out and cleaned with a brush or  
flowing water.  
4. Remove dirt and lint condenser fins  
and the unit compartment with a brush  
attachment on a vacuum cleaner.  
5. Put back the filter and reassemble  
the front cover.  
6. Plug in the icemaker or reconnect  
power.  
DO NOT touch the condenser fins. 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, 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.  
• Many ice machine cleaners  
contain acids.  
• DO NOT use or mix with any  
other solvent-based cleaner  
products.  
• Use rubber gloves to protect  
your hands.  
• Carefully read all safety  
instructions printed on the  
container of the ice machine  
cleaner.  
.
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.  
• Discard the first batch of ice  
produced after cleaning.
