⊙ Places without heat source
◆ The product has to be installed at places without a heat
source such as stove or gas range or any place
with ambient temperature of 10 ~ 38 ℃(50~100 ℉).
⊙ To the place with enough spaces from the walls
◆ The minimum distance required is 20cm(8") from
the walls for normal operation.
◆ Make sure that there is a minimum gap of 45cm(17.7")
from the top of the product for clearing and maintaining
the auger.
⊙ To the place with good ventilation
◆ Poor ventilation will lead to poor ice-making capability.
⊙ On even surfaces
◆ Uneven surface will result in too much vibration or noise.
(The surface angle must be less than 1˚)
◆ Installing the product on an uneven surface may
cause it to fall or slip and cause injury.
Make sure that the product is installed on an even surface.

⊙ Be sure to install the product in clean places.
◆ Ice will be used for food or human consumption.
Thus, the installation site must be clean and hygienic.
⊙ The product must be installed indoors.
◆ The outlet of the drain hose has to face downward
to enable smooth draining.
◆ The product must not be installed outside.
⊙ In a place inaccessible to children.
◆ Be sure to apply caution so that children
neither get injured nor play with ice.
◆ Make sure to observe the following.
● Since the product makes use of water, proper water supply and draining facility are required.
● Water may leak during installation or operation for diverse reasons. Thus, proper draining must be prepared.
Since there is danger of electric shock due to moisture from leak, be sure to observe the following:
1. When installing the product indoors, be sure to have a natural drainage facility and make
the floor waterproof, especially if the floor may get damaged due to leak.
2. A draining outlet must be available at the installation site; be sure to connect the drain hose.
3. Make sure that the floor is sloped so that any leaked water gets drained away
even if the drain hose gets dislodged or damaged. Install a water overflow prevention
wall to prevent damage.
※ Adjust the height by turning the footing if the floor is sloped to set it stably.
※ The manufacturer will not be liable for any problem arising from failure to comply
with the warnings above, dislodged / damaged water supply hose, or inappropriate drain facility.

How to install the storage bin
Installing the ice maker and connecting storage bin
1. Unpack the ice storage bin and make sure that it will not be
moved after installation.
2. Connect the drain hose at the bottom outlet part and fully tighten
the joints at the connecting part in order to minimize leaks.
3. Adjust the 4 adjustment feet of the storage bin to level it.
(Adjustment must be less than 1˚ for all 4 feet)
1. Use the lifting device to put the ice maker on top
of the bin. Otherwise, at least 2 to 3 persons must
work together to put the ice maker on the bin.
2. As the first phase, put the ice maker on a loading platform.
(Height of loading platform: Minimum of 1m(39.4")
is recommended)

(Head)
3. As the second phase, move the ice maker
from the platform to the top of the bin.
◆ Be sure to apply more power to the right part of the ice
maker since it is heavier due to the compressor therein.
Tighten the joints at the connecting part, face the outlet
of the hose upward, and pour some water into the bin
to check for leaks.

4. Move the ice maker little by little until the front door opens freely.
5. Screw the fixing brackets to the back of the ice maker.

The quantity of ice may decrease if the supplied water is too hot, and ice making may not work
properly if the water pressure is too low, which can be supplemented by installing an auxiliary
water pressure pump.

About grounding
※ Be sure to ground the product to prevent electric shock.
⊙ Grounding method - if there is a grounding terminal
In case of plugging the icemaker into an rating AC outlet equipped with a grounding
terminal, extra grounding is not necessary.
⊙ Grounding method - if there is no grounding terminal
In case of plugging the icemaker into an rating AC outlet without a grounding terminal,
connect the ground wire to the copper plate and then bury it under the ground.
Do not ground the product on the following:
Gas piping, water supply, lightning rod, telephone line, or any connection part
※Plastic water piping or non-insulated material will not provide a grounding effect.

After installation
⊙ Protection of the water supply hose
Do not put any heavy object on the water supply
hose. Do not step on it either.
⊙ The appropriate water pressure, water temperature,
or ambient temperature is...
This ice maker must be used under conditions of 1~5 kg/㎠,
water supply of 10~32 ℃(50~90 ℉), and ambient temperature
of 10~38 ℃(50~100 ℉).
◆ This icemaker operates only on rating volts.
Plug it into a rating outlet only.
◆ Open the faucet to supply water to the icemaker.
◆ Turn on the earth leak breaker on the back and the power switch
on the display panel on the front to initiate the ice making operation.
◆ When the water tank is full, turn the power switch to "DRAIN"
to drain water for about a minute, and then turn it back to "ICE"
for ice making.
◆ The time may vary depending on the ambient temperature
and water temperature, but it will take about 5 minutes before
ice cubes are produced.
Connect potable water supply only.
