Use two or more people to move and install the ice maker. Failure to do so can result in
back or other injury.
To ensure proper ventilation for your ice maker, the front of the unit must be completely
unobstructed. Choose a well ventilated area with temperatures above 50°F (10°C) and
below 100°F (38°C). This unit MUST be installed in an area protected from the elements,
such as wind, rain, water spray or drips.
The ice maker should not be located next to ovens, grills or other sources of high heat.
The ice maker must be installed with all electrical and water connections in accordance
with state and local codes. A standard electrical supply (115 V AC, 60 Hz, 15 A), properly
grounded in accordance with the National Electrical Code and local codes and ordinances,
is required.
3
Do not kink or pinch the power supply cord between the ice maker and cabinet.
The fuse (or circuit breaker) size should be 15 amperes.
It is important for the ice maker to be leveled in order to work properly. If the ice maker is
not level, water may not flow properly through the evaporator (ice mold) and ice
production will be less than normal. Several adjustments may be required in order to level
the ice maker.
All installations must be in accordance with local plumbing code requirements.
Make certain that hoses are not pinched, kinked or damaged during installation.
Check for leaks after water line is connected.

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 that
has a voltage rating that matches the rating label on the appliance. This will ensure the best
performance and also prevent possible overloading of 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. Immediately
repair or replace any 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

This ice maker should be properly installed by qualified personnel.
To ensure proper ventilation for your ice maker, the front of the unit must be completely
unobstructed.
When installing the ice maker under a counter, follow the recommended spacing
dimensions shown above. Allow at least 4" (102 mm) clearance at rear, and 1"(25 mm)
at top and sides for proper air circulation. The ice maker should be installed in such a
way that allows the unit to be pulled forward for servicing, if necessary.
Choose a well ventilated area with temperatures above 50°F (10°C) and below 100°F
(38°C). This unit MUST be installed in an area protected from the elements (i.e. wind,
rain, water spray or drips).
The unit should not be located next to ovens, grills or other high heat sources.
Installation of the ice maker requires a cold water supply inlet of ¼-in. (6.35mm) soft
copper tubing with a shut-off valve.
The ice maker requires a continuous water supply with a minimum pressure of 15 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.
8
Normal operating ambient temperature should be between 50°F (10°C) to
100°F (38°C). Normal operating water temperature should be between 41°F
(5°C) and 90°F (32°C). Operation of the ice maker for extended periods outside of these normal temperature ranges may affect production capacity.
It is strongly recommended that a water filter be used. A filter, if it is of the
proper type, can remove taste and odors as well as particles. Some water is very hard,
and softened water may result in white, mushy cubes that stick together. Deionized water
is not recommended.
The ice maker must be installed with all electrical and water connections in accordance
with all state and local codes.
The unit should be located on a firm and level surface. 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 caster. See the Leveling the Ice Maker section.
A standard electrical supply (115V AC only, 60Hz, 15A), 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:
o A standard electrical supply (115V AC 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 a
receptacle 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 matching 3-prong, grounding-type wall receptacle and
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 ice maker to be leveled in order
to work properly. If the unit is not leveled, water will
not flow properly through the evaporator (ice mold) and
ice production may be less than normal. The unit may
also be noisy. The unit can be raised or lowered by rotating
the plastic sheaths around each of the four rolling
casters on the bottom of the machine. If you
find that the surface is not level, rotate the casters
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.
down
up
1. Place a carpenter’s level on top of the unit to see if the ice maker is level from front to
back and side to side .
2. Adjust the height of the casters as follows:
Turn the leveling casters to the right to lower that side of the ice maker.
Turn the leveling casters to the left to raise that side of the ice maker.
You will find that the casters make it easy for one person to move the machine. This is
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: When the ice maker is ready to be installed in a cabinet or directly on the
10
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.
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. Remove the top hinge cover.
2. Using a Phillips screwdriver, remove the screws and then remove the top hinge mat and
top hinge. Keep the parts together and set them aside.
3. Lift the door off of the bottom hinge and set the 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 front louver. Set aside.
3. Remove the bottom hinge and place it on the opposite side at the bottom of the door.
4. Position the door on the bottom hinge.
5. Align the door on the bottom hinge and replace the top hinge and top hinge mat.
6. Replace top hinge cover.
7. Push the plug buttons into the original screw holes.
See Figure below.
11
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 machine will make installation easier.)
IMPORTANT:
1. All installations must be in accordance with local plumbing code requirements.
Professional installation is recommended.
2. Make certain the hoses are not pinched or kinked or damaged during installation.
3. Check for leaks after connection.
Tools required:
½-inch Open-End Wrench, Phillips Screwdriver
Connecting the water line:
1. Turn off main water supply. Turn on the 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 the nut of the water supply hose to the tap, and connect the other end with the
water inlet. 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 connection at the water inlet).
IMPORTANT: When you connect the water supply hose and the drain hose, pay attention to
the indications of “Water inlet” and “Drain outlet” on the machine.
Drain
Note: You must connect the drain line before using the ice maker.
below.
Connecting the drain line:
Follow the steps outlined
NOTE: If there is a drain line near the ice maker, the best choice to drain water to the
drain line is through the drain water 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 water 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 end of the hose into the drain line.
12
NOTE: Never allow the drain hose to hang or loop higher than the floor of the ice storage
bin.
3. All horizontal runs of drain lines must have a fall of ¼” per foot. An air gap will likely
be required between the ice maker drain tube and the drain/waste receptacle. A standpipe
with a trap below it would be acceptable for the drain/waste receptacle. A floor drain is
also acceptable. If this is not possible, MC Appliance Corporation recommends the use
of a condensation pump. Contact MC Appliance Corporation customer service at
888-775-0202
4. Pour 1 gallon of water into the ice storage bin to check for leaks in the drainage system.
Tighten any connections that leak.
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.
13
Installation Types
This ice maker has been designed for Mobile (free-standing) installation. However, it can
also be enclosed (as under a cabinet) or Built-in (sealed to the floor). In any case, there must
be adequate air space around the unit for ventilation.
Mobile installation:
A mobile installation will allow you to install the ice maker, free-standing, in any place you
desire provided you have access to a water supply and drain. You must follow the stated
instructions for
a. Electrical requirements
b. Water supply
c. Drain Connection
d. Leveling the ice maker.
Enclosed Installation:
An enclosed installation will allow you to install the ice maker under a cabinet or in a
kitchen cabinet provided the required clearance space around the ice maker is respected.
This installation has the same requirements as a mobile installation.
Built-in installation:
If this method of installation is chosen, it will still be necessary to allow adequate ventilation
space around the unit. The following additional items must be observed.
1. Place ice maker in front of 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 line must be plumbed before connecting to the ice maker.
3. The drain line must be connected. If you do not have a floor drain, you will require a
condensation pump.
4. Turn on main water supply and tap. Check for water supply connection leaks. Tighten
every connection (including connection at the water inlet).
5. If the electrical outlet for the ice maker is behind the cabinet, plug in the ice maker.
6. Push the ice maker into position.
7. Seal all around the cabinet to the floor with an approved caulking compound.
IMPORTANT: Be sure the drain hose is connected and fed into the drain line before the ice
maker is moved into its final position.

Operating method
1. Turn on the water tap, let the water trough fill, then press the ON/OFF button on the front
panel. The ice maker will start working automatically.
Ice making stage
Ice harvest stage
Bin full stage
2. After 3 minutes, the machine will automatically go to the ice-making stage, and the
sound of water flowing will be heard.
3. When the batch of ice has been fully formed, ice will automatically be harvested to the
15
ice storage bin.
4. When the ice storage bin is full, the sheet of cubes will not fall completely and will hold
the bin-full probe open. The machine automatically stops making ice and progresses to
the cold preservation stage. During this stage, the compressor works regularly to keep
the temperature low to minimize ice melting.
5. The unit will start making ice again after the ice cubes are removed. Then the bin-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 evaporator when unit 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
Set the ON/OFF button to the ON position. The machine will automatically go to the ice
making stage.
There are two distinct cycles: ice freeze and harvest.
The freeze cycle happens when water flows to the evaporator surface. The harvest cycle is
when the ice is released and water enters the machine. A complete cycle takes about 20
minutes, but it depends 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 harvest cycle begins.
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 hot
refrigerant 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 freezes and sticks to the ice cube molds. The water containing impurities
falls back into the water trough. During the ice making process, fresh water enters into the
water trough continuously as the water in the trough freezes continuously in the evaporator.

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 amplify the sounds to make it seem
louder than they actually are. The following list describes the 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 maker can also make noises.
The high efficiency compressor may make a pulsating or high-pitched sound.
Water running 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 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.
1. Shut off the water supply at the main water source.
2.
3.
4.
5.
6.
Disconnect the water supply line from the water inlet.
Shut off the electric supply at the main electrical power source.
Take out the ice storage bin to remove any remaining ice and water. Dry the bin.
Pull off the drainage tube of the water trough to drain off all water.
Leave the door open to allow for circulation and to prevent mold and mildew.
17
7. Leave 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. Grasp the plug and pull out firmly.
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
solutions. Do not leave any solution 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 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 parts 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
18
Before proceeding with cleaning and maintenance
operations, make sure the power line of the unit is
disconnected and the water line is shut off.
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 steel, stainless steel can discolor when exposed to chlorine gas
and moisture. Clean stainless steel with a mild detergent and warm water solution and a
damp cloth. 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 or when 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 the power to the unit.
2. Open the door and take out the removable ice storage bin. With a clean cloth, wipe down
the interior of unit and ice bin with a sanitizing solution made of 1 ounce of household
bleach or chlorine and 2 gallons of hot (95ºF – 115ºF) water.
3. Rinse thoroughly with clear water.
4. Screw off the drainage nut to drain completely.
5. Put the ice storage bin inside the unit.
6. 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 and
damage or discolor the interior.
19
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.
Unplug the ice maker or disconnect power.
Gently pull off the lower front louver.
Remove dirt and lint from the condenser fins and the
unit compartment with a brush attachment of a
vacuum cleaner.
4. Reassemble the lower front louver.
5. Plug in the ice maker or reconnect power.

DO NOT touch the condenser fins. They are sharp and can be easily damaged.
Water distribution tube cleaning
When you find the ice cubes are incompletely formed or the output is low, the water
distribution tube may be blocked. Turn off the power button, rotate the water distribution
tube, locate the holes in the distribution tube and use a pointed object such as a toothpick to
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.
2.
3.
4.
Shut off the water supply
Disconnect the water hose from the distribution tube.
Lift the right side up and then remove the distribution tube.
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 and sanitizing
Minerals that are removed from the 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 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
20
grains/ liter), you may need to clean the system as often as once every 6 months.
1. Make sure that all the ice is off the evaporator. If ice is being formed, wait until the cycle
is completed, then press the machine’s ON/OFF switch on the control panel.
2. Remove all ice 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 trough. Then press the ON/OFF switch and the CLEAN
button, initiating the wash cycle. The machine will run in the Automatic Clean Mode.
4. Allow 30 minutes for proper cleaning. After cleaning, press the ON/OFF switch again.
Use a drain hose on the front of the water trough to drain off the waste water into a
convenient container.
NOTE: Do not drain the waste water into the inside of the cabinet.
5. Repeat steps 3 and 4 (without Ice Maker Cleaning Solution) three times to rinse the ice
making system thoroughly.
NOTE: 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 produced after cleaning.
6. Prepare a sanitizing solution made of 1 ounce of household bleach and 2 gallons of hot
water (95º to 115ºF). Wipe the entire bin inside and outside, covering the entire surface
of the walls.
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. Let dry.
9. Repeat steps 1 to 5, but instead of using a Nickel Safe Ice Maker Cleaner Solution, use
the sanitizing solution from step 6. In addition, fill the water trough to its maximum
level
10. Repeat step 5 to rinse the ice making system one more time.
11. Press the ON/OFF button again. The machine will return to the regular ice making mode.
Discard the first batch of ice.

Control panel:
Description of LEDs and buttons:
1. Bin Full (Red) LED: Bin full indicator light
When this is lit, the ice storage bin is full of ice or there is something blocking the
bin-full probe. The unit will stop working. When ice cubes are removed from the ice
storage bin, freeing the bin-full probe, the Red LED will remain flashing for 3 minutes,
then the unit will restart and return to the ice making mode.
2. Ice Making (Green) LED: Ice making indicator light
When this is lit, the unit is working in the ice making mode controlled by a temperature
probe on the evaporator. When the Ice Making (Green) LED flashes, the unit is working
in the ice making mode controlled by a fixed timer.
3. Ice Harvest (Yellow) LED: Ice harvest indicator light
When this is lit, the unit is working in the ice harvest mode controlled by the ice-full
probe.
Note: When both the Green and Yellow LEDs are lit, the unit is in the cold preservation
mode.
4. Mode button: Mainly used when servicing the ice maker.
When this is pressed, the ice making mode changes to the ice harvest mode or vice versa.
The mode can be judged from the status of the Green and Yellow LEDs.
Ice Size Adjustment Guide:
1. Press and hold the “Clean” button and the “Mode” button together for at least 3 seconds.
The unit will enter the Ice Size Adjustment mode. The Ice Harvest (Yellow) LED will
blink continuously during the ice size adjustment.
2. While in the Ice Size Adjustment mode, press the “Clean” button to decrease the ice size
or the “Mode” button to increase the ice size to your desired level. See below for details.
22
Smaller ice setting:
By pressing the “Clean” button, you can decrease the size of the ice cubes. The Ice Making
(Green) LED will flash as you lower the ice size and will blink continuously when the
setting of the smallest ice size has been reached.
Larger ice setting:
By pressing the “Mode” button, you can increase the size of the ice cubes. The Bin Full
(Red) LED will flash as you increase the size and will blink continuously when the setting
of largest ice size has been reached.
After 10 seconds without any operation, the unit will return to the previous mode.
NOTE: During the ice size adjustment, the “BIN FULL”, “ICE MAKING” and “ICE
HARVEST” LEDS blinking all at once indicate that the unit is in the default factory
setting of the ice size.
MAJOR FUNCTIONS
1. The operating procedure is completely automatic.
2. When the ice storage bin is full of ice cubes, the machine stops making ice and proceeds
to the cold preservation stage automatically. It starts making ice again after ice cubes are
removed.
3. The different colors of the LED display indicate various work modes.
4. 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.
5. A sensitive probe and accurate timer enhance the performance of the ice maker.
6. A compressor protection system is built in.
