SAVE THESE INSTRUCTIONS
Electrical Connection
Do not, under any circumstances, cut or remove the third (ground) prong from the
power cord. For personal safety, this appliance must be properly grounded. The power
cord of this appliance is equipped with a 3-prong grounding plug that mates with a
standard 3-prong grounding wall outlet to minimize the possibility of electric shock
hazard from the appliance. Have the wall outlet and circuit checked by a qualified
electrician to make sure the outlet is properly grounded. When a standard 2-prong wall
outlet is encountered, it is your responsibility and obligation to have it replaced with a
properly grounded 3-prong wall outlet. The ice maker should always be plugged into
its own individual electrical outlet which has a voltage rating that matches the rating
label on the appliance. This provides the best performance and also prevents
overloading house wiring circuits which could cause a fire hazard from overheated
wires. Never unplug your ice maker by pulling on the power cord. Always grip the
plug firmly and pull straight out from the outlet. Repair or replace immediately all
power cords that have become frayed or otherwise damaged. Do not use a cord that
shows cracks or abrasion damage along its length or at either end. When moving the
ice maker, be careful not to damage the power cord.

Location Requirements
INSTALLATION CLEARANCES:
TOPVIEW SIDEVIEW
•To ensure proper ventilation for your ice maker, the front of the unit must be completely
unobstructed. Allow more than 4” clearance at rear, 0.6” at top and sides for proper air
circulation. The installation should allow the ice maker to be pulled forward for servicing if
necessary.
• When installing the ice maker under a counter, follow the recommended spacing dimensions
shown. Place electrical and water supplies and drain fixtures in the recommended locations as
shown.
• Choose a well-ventilated area with temperatures above 50ºF (10ºC) and below 100ºF (38ºC).
This unit MUST be installed in an area protected from the elements, such as wind, rain, water
spray or drips.
• The unit should not be located next to ovens, grills or other sources of high heat.
• Installation of the ice maker requires a cold water supply inlet of 1/4 in. soft copper tubing
with a shut-off valve and a gravity-drain system.
• The ice maker requires a continuous water supply with a minimum pressure of 20 psig and a
static pressure not to exceed 80 psig. The temperature of the water feeding into the ice maker
should be between 41°F (5°C) and 90°F (32°C) for proper operation.
Normal operating ambient temperature should be between 50ºF
(10ºC) to 100ºF (38ºC). Normal operating water temperature
should be between 41ºF (5ºC) and 90ºF (32ºC). Operation of
the ice maker for extended periods outside of these normal
temperature ranges may affect production capacity.
• In general, it is always a good idea to filter the water. A water filter, if it is of the proper type,
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.
• The ice maker must be installed with all electrical, water and drain connections in accordance
with state and local codes.
• The unit should be located on a firm and leve urface. It is important for the ice maker to be
leveled in order to work properly. If needed, you can adjust the height of the ice maker by
revolving the feet. See the “Leveling the Ice Maker” section.

Failure to follow these instructions can result in fire,
electrical shock or death.
A standard electrical supply (115VAC, 60 Hz, 15 A), properly grounded in accordance
with the National Electrical Code and local codes and ordinances is required.
IMPORTANT: Do not kink or pinch the power supply cord between the ice maker and wall
or cabinet.
Before you move your ice maker into its final location, it is important to make sure you have
the proper electrical connection.
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. This appliance 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.

10
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.
Under block
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 and Drain Connections
The water supply and drain should be ready at the point of installation. 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. Professional
installation is recommended.
2. Make certain that the hoses 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:
Turn off main water supply. Turn on nearest faucet long enough to clear line of water.
Find a ½ in. to ¾in. vertical cold water pipe near the installation location. 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.
Connect nuts of water supply hose to tap and water inlet connector of the ice machine.
Tighten firmly by hand, then one-half turn with wrench.
Turn on main water supply and tap. Check for water supply connection leaks. Tighten any
connections or nuts that leak.
Turning the under block
counter-clockwise reduces
the machine’s height
Turning the under block
clockwise increases the
machine’s height

11
NOTE: Connection to the water line may vary according to installation requirements.
Drain
IMPORTANT: This ice maker is not a freezer, it must connect to a drain line. Your
machine comes equipped with a gravity drain. Depending on your plumbing setup, a
condensation pump may be required. Poor drainage will cause a high rate of melting in
the ice storage bin and may cause flooding or your machine to shut off.
Connecting the drain line:
NOTE: If there is a drain line near the ice maker, the best choice is to drain water to
the drain line through the drain hose provided with ice maker.
1. Locate the floor drain near the ice maker. The distance should be less than 5 feet since
the length of the long drain hose provided with the ice maker is about 5 feet.
2. Find the drain outlet on the back of ice maker, connect the drain outlet to the water
draining hose, and insert the other side of the hose into the drain line.
NOTE: The drain hose should never be allowed to hang or loop higher than the bottom
of the ice storage bin.
3. 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 leaks at all drain connections
and at the drain water hole. Tighten any connections or nuts that leak.

12

Operating Method
1. Remove the two screws at the bottom of the front cover.
2. Grasp the right and left sides of the front cover，
raise it a little and then take it off. Press the ON/OFF
switch beside the condenser. The light will be on. The
ice maker will startworking automatically and feeding
water.
3. 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.
4. Ice will be harvested to the ice storage bin. When
the storage bin is filled to the point that the ice-full sensor is
covered, the ice maker will automatically stop working. The machine will
restart making ice once the storage bin is less than full.
5. Excess water will flow through the drain outlet at the back of the machine and empty into
the floor drain.
IMPORTANT:
• Although the unit has been tested 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 icemaker is working.
How the Machine Makes Ice
There are two distinct cycles: freeze and harvest.
During the freeze 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 30 minutes, but is dependent 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 to harvest the ice.
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 and the water inlet
valve. These two valves open and warm up the freezing surface, allowing the cubes to fall
into the bin. The freeze cycle will restart when all the cubes have been harvested.
Front cover
Power switch

15
How the machine uses water:
The ice maker begins with a
fixed charge of water that is
contained in the water sump.
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. freezing portion
of the ice-making cycle, the
water in the sump will become
highly concentrated with
mineral impurities. During the
harvest cycle, fresh water
flows into the machine to
dilute the bin water and
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 and 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.
You will hear a swooshing sound when the water valve opens to fill the water sump 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 sump to the evaporator plate may make a splashing sound.
Water running from the evaporator to the water sump may make a splashing sound.
As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your ice
maker.
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 system of water.

16
Shut off the water supply at the main water source.
Disconnect the water supply line from the water inlet valve.
Disconnect the drain pipe to the drain line or floor drain.
Allow the ice maker to run for an hour or more until all remaining ice cubes have been
ejected from the ice maker assembly.
Shut off the electric supply at main electrical power source.
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.
Drop the door open to allow for circulation and prevent mold and mildew.
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
bethoroughlycleaned.Followcarefullyanyinstructionsprovidedfor
cleaning or use of sanitizing solution.
Donotleaveanysolution inside the ice maker 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.
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

17
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 cleaning).
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.
Stainless steel can discolor when exposed to chlorine gas and should be cleaned. Clean stainless
steel with a mild detergent and warm water solution and a damp cloth. Never use abrasive
cleaning agents.
NOTICE: Stainless steel exposed to chlorine gas and moisture, such as in areas with
spas or swimming pools, may show some discoloration. Discoloration from chlorine gas
is normal
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 two screws at the bottom of the front cover.
3. Grasp the right and left sides of the front cover，raise it a little
and then take it off.
NOTE: Do not use too much force, as the top side of the front
cover can beinadvertently damaged by the lower
corner of the door.
4. Locate the condenser filter. This can be taked
off and cleaned with a brush or flowing water.
5. Remove dirt and lint from the condenser fins and
the unit compartment with a brush attachment of a vacuum cleaner.
6. Put back the filter and reassemble the front cover.
7. Plug in the ice maker or reconnect power.
DO NOT touch condenser fins. They are sharp and
can be damaged easily.

18
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 1 ounce of household bleach or chlorine and 2 gallons 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.
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.
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. Disconnect power to the unit
2. Using a Phillips screwdriver, remove
the screws (A) at rear of the unit, lift
up the rear side of the top cover and
push it forward, then remove the top
cover. Keep the parts together and
set them aside.
3. Open the door.
4. For KD-70/110, take out the row of
