• The dispenser performs best at room temperature of 50~75°F and a supply of water at 50°F.
• The dispenser should only be installed indoors and should NOT be installed near heat generators such as heaters,
stoves, or dishwashers
Product Installation
Where there is no heat source.
※Install in a place where there is no heating device
such as a fireplace or a gas range and do not install in an
area outside the range of 10 ~ 38 ℃/50 ~100oF.
Allow enough ventilation
• For normal operation, install the dispenser at least 4
inches away from the back wall and 6 inches above the top
of the dispenser.
※Never block the upper vents and do not place any
load on it.
• Poor ventilation will decrease the unit’s ability to
make ice.
Install on a flat surface
※Unstable installation may cause vibration and noise.
The recommended angle of installation is 1o
• A flat surface is recommended because there is a
possibility that the product will fall and cause injury when
the installation is made in a sloping place.
• Installation should be indoors in a clean place
• The drain hose should be installed at an angle so that drainage is good.
• During installation and use, water leakage may occur due to various reasons. It must be used at a
place where drainage facilities are fully equipped
• When installing the product indoors (places such as living room, store, the floor where damage
may occur due to leakage), please install natural drainage facilities and waterproof the floor.
• Even when installing in the kitchen, a drain hole must be provided, and a drain hose must be
connected.
• The manufacturer shall not be held responsible for the spreading damage caused by insufficient
drainage facilities in case of the above-mentioned problems and problems due to water supply hose
deviation or breakage.

11
Requirements for plumbing
Plan the arrangement of the water supply pipes.
Connect a 1/4" diameter copper cable with the tap water pipe.
Install a shutoff valve between the tap water pipe and the product so that the user can operate the valve.
Do not install the shutoff valve at the back of the product. Do not use a self-piercing valve. If the tap water
has a high level of minerals, a pipeline filter will be required.
The pressure of the tap water should be maintained at a level between 20psi (1.4bar) and 80psi (5.5bar).
The tap water and drain pipeline should be planned and prepared at the place of installation. If an electric
outlet is available just at the back of the ice maker, installation may be easier. The electric power, tap water
pipeline and drain pipeline should satisfy all the provisions under local laws and regulations. For the position
of the tap water, refer to the installation specifications and drawings on pages 10 and 11.
Important Information: The dispenser is designed for use in a fixed position but it may be necessary to pull
the unit forward for service. Therefore, do not install any material at the front, upper or lower end of the
product which may act as an obstacle when moving the ice maker.
Water quality
• There is no such thing as “perfectly pure” water. All kinds of water including tap water contain some
impurities. Rainwater absorbs impurities from the atmosphere or when it passes through soil. Some
impurities consist of solid particles called suspended solids and are filtered through micro filters. Any
remaining impurities cannot be filtered because they are chemically combined with water molecules.
These impurities are called dissolved solids.
• The mineral content of the ice produced by the dispenser is reduced compared to the content in the
water before conversion into ice. Water containing a low level of impurities is rapidly frozen. The
reason for this is that the impurities elevate the temperature of the water. Through such action, most
of the impurities condensed in the water-tank of the dispenser form a hard precipitation called scale.
• This dispenser reduces the mineral level by circulating water during the harvest cycle (the excessive
quantity is removed through the outlet tube). Each cycle requires about 0.64 quart (0.6ℓ) of water. For
each quart, about 0.5 quart is used in rinsing the water tank and the remaining quantity is removed
through the outlet pipe. In this process, some impurities unavoidably remain and may accumulate on
the internal parts of the ice maker, forming abnormally-shaped ice cubes. If a large quantity of mineral
scale accumulates, the lifespan of the dispenser may be reduced.
• For best operation of the ice maker, impurities and minerals should be decomposed by washing
periodically. The method of cleaning the dispenser is described on pages 18 -19.
• In general, it is best to use filtered water. Filters may remove not only bad odor but also particles.
Neutral water is not recommended.
• Water softener is not recommended because it exchanges minerals. If the hardness of the water is
very high, softening may lead to the formation of opaque pieces of ice.
• If you have any questions about the purity of your water, address your inquiry about water treatment
to an expert in water quality.
• This product was thoroughly washed at the factory. However, check the cleanness of the inside before
use and keep it clean during use.

12
Requirements for power supply
120VAC, 60Hz, 15-amp circuit breaker and electric power are required. A separate circuit is required for
grounding.
The power cord of the product should be inserted into a suitable 3-prong grounding-type socket.
Important Information: A Ground Fault Circuit Interrupter (GFCI) is not recommended because it could cause
the operation of the product to stop.
Important Information: The provisions of the National Electric Code as well as any local laws and instructions
should be observed when installing the product.
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 dispenser 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 dispenser 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 dispenser.
Warning!
Do not use extension cords or 2-prong adapters. The product must be grounded.
Never cut off the grounding terminal of the 3-prong grounding plug.
