cleaning products. Use rubber gloves to protect hands. Carefully read the safety
instructions on the container of the ice machine cleaner.
•Do not use the apparatus other than for its intended purpose.
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.

•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. Allow at least 4" (102 mm) of clearance at rear, and 1" (25 mm) at
sides for proper air circulation. The installation should allow the ice maker 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).
•Placing the unit at least 24″from high heat sources (fireplaces, grills, ovens, etc.) will
ensure minimal energy consumption.
•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.
•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 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 icemaker and wall or cabinet.
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.

Electrical requirements
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 (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 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 ground 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.

10
Leveling the ice maker
It is important for the ice maker to be leveled in order
to work properly. Otherwise water will not flow
properly through the evaporator (ice mold). The
ice production will be less than normal, and may
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.
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
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 top hinge cover by pushing it toward the back of the unit, then lifting it off.
2. Using a Phillips screwdriver, remove the screws, 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. Replace the axis on the door hinge 1 and tighten it firmly. Remove the door hinge 1
and place it on the opposite bottom side.

replace axis on the hinge 2. Tighten it firmly.
5. Push the plug buttons into the original screw holes.
See Figure below.

12
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-in. 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 6 feet. The water supply hose provided with the ice maker
is about 6 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
You must connect the drain line before using the ice maker. You must connect the drain line before
using the ice maker. Follow the steps outlined below.
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 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.
NOTE: Never allow the drain hose to hang or loop higher than the floor of the ice
storage bin.

13
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, the use of a condensate pump is
recommended.
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. Infrequent drainage will
cause a high rate of melting in the ice storage bin.

14
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. You must follow the stated instructions
for

15
a. Electrical requirements
b. Water supply
c. 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. Turn on main water supply and tap. Check for water supply connection leaks. Tighten

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 stops making ice automatically.
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 the 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.

18
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 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. 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 any remaining ice and water. Dry the bin.
5. Pull off the drainage tube of the water trough to drain off all water.

6. Leave the door open to allow for circulation and to prevent mold and mildew.
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.
CLEANINGAND 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 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
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.
