IMPORTANT SAFEGUARDS
Before the ice maker is used, it must be properly positioned and
installed as described in this manual, so read the manual carefully. To
reduce the risk of fire, electrical shock or injury when using the ice
maker, follow basic precautions, including the following:
zPlug into a grounding outlet, do not use an adapter, and do not use an extension
cord.
zIt 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.
zDo not connect or disconnect the electric plug when your hands are wet.
zNever clean ice maker parts with flammable fluids. These fumes can create a fire
hazard or explosion. And do not store or use gasoline or other flammable vapors
and liquids in the vicinity of this or any other appliance. The fumes can create a
fire hazard or explosion.
zBefore 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’s cleaning).
zReplace all panels before operating after servicing or maintenance.
zUnplug the ice maker or disconnect power before cleaning or servicing. Failure to
do so can result in electrical shock or death.
zDo not attempt to repair or replace any part of your ice maker unless it is
specifically recommended in this manual. All other servicing should be referred
to a qualified technician.
zWhen you disassemble the front cover, don’t overexert, or the leads connected
with the power switch can be torn down.
zUse two or more people to move and install ice maker. Failure to do so can result
in back or other injury.
zTo ensure proper ventilation for your ice maker, the front of the unit must be
completely unobstructed. Choose a well-ventilated area with temperatures above
13℃and below 32℃. This unit MUST be installed in an area protected from the
elements, such as wind, rain, water spray or drips.
zThe ice maker should not be located next to ovens, grills or other sources of high
heat.
zThe ice maker must be installed with all electrical, water and drain connections in
accordance with state and local codes.A standard electrical supply (115VAC,
60Hz,15A), properly grounded in accordance with the National Electrical Code

4
and local codes and ordinances is required.
zDo not kink or pinch the power supply cord between the ice maker and cabinet.
zThe appliance is to be connected to the water mains using new hose-set and that
old hose-sets should not be reused.
zIf the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similar qualified person in order to avoid a hazard.
zThe plug must be accessible after installation.
zAll horizontal runs of drain lines must have a fall of 2cm per meter.
zIt is important for the ice maker to be leveled in order to work properly. You may
need to make several adjustments to level it.
zAll installations must be in accordance with local plumbing code requirements.
zMake certain that the pipes are not pinched or kinked or damaged during
installation.
zCheck for leaks after water line and drain line connection.
zNever allow children to operate, play with or crawl inside the ice maker.
zAlthough the unit has been tested at the factory, due to long-term transit and
storage, the first batch of cubes must be discarded.
zNever turn the water supply tap off when the ice maker is working.
zIf the ice maker will not be used for a long time, before the next use it must be
thoroughly cleaned. Follow carefully any instructions provided for cleaning or
use of sanitizing solution. Do not leave any solution inside the ice maker after
cleaning.
zDO NOT touch the condenser fins. The condenser fins are sharp and can be easily
damaged.
zDO 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.
zThe 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.
zDo not use this apparatus for other than its intended purpose.
SAVE THESE INSTRUCTIONS
Electrical Connection
For personal safety, this appliance must be properly grounded. The power cord of
this appliance is equipped with a grounding plug that mates with a standard
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 grounding 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

5
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.
Extension Cord
Because of potential safety hazards under certain conditions, it is strongly
recommended that you do not use an extension cord with this ice maker.
IMPORTANT SAFETY INSTRUCTIONS
WARNING: To reduce the risk of fire, electric shock, or injury
when using your ice maker, follow these basic precautions:
zPlug into a grounding wall outlet.
zDo not remove grounding prong.
zDo not use an adapter.
zDo not use an extension cord.
zDisconnect power before cleaning.
zDisconnect power before servicing.
zReplace all panels before
operating.
zUse two or more people to move
and install ice maker.

IMPORTANT: Do not remove any permanent instruction labels or the data label
on your ice maker.
Remove tape and glue from your ice maker before using.
•To remove any remaining tape or glue, rub the area briskly with your thumb.
Tape or glue residue can also be easily removed by rubbing a small amount of
liquid dish soap over the adhesive with your fingers. Wipe with warm water
and dry.
•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 ice maker.

Location Requirements
To ensure proper ventilation for your ice maker, the front of the unit must be
completely unobstructed. Allow at least 150 mm clearance at rear, and 40 mm
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 13℃and below 32℃.
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 19mm O.D.
soft copper tubing with a shut-off valve. A gravity-drain system provided with the
unit can be used.
(NOTE: Runoff water can also be drained into a sink via a pump – not included –
when a gravity drain is not available.)
The ice maker requires a continuous water supply with pressure between 0.1Mpa
and 0.5Mpa. The temperature of the water feeding into the ice maker should be
between 5℃and 25℃ for proper operation.
