Please observe the following safety precautions in order to
use safely and correctly the refrigerator and to prevent
accident and danger during repair.
1. Be care of an electric shock. Disconnect power cord
from wall outlet and wait for more than three minutes
before replacing PWB parts. Shut off the power
whenever replacing and repairing electric components.
2. When connecting power cord, please wait for more than
five minutes after power cord was disconnected from the
wall outlet.
3. Please check if the power plug is pressed down by the
refrigerator against the wall. If the power plug was
damaged, it may cause fire or electric shock.
4. If the wall outlet is over loaded, it may cause fire. Please
use its own individual electrical outlet for the refrigerator.
5. Please make sure the outlet is properly earthed,
particularly in wet or damp area.
6. Use standard electrical components when replacing
them.
7. Make sure the hook is correctly engaged.
Remove dust and foreign materials from the housing
and connecting parts.
8. Do not fray, damage, machine, heavily bend, pull out,
or twist the power cord.
9. Please check the evidence of moisture intrusion in the
electrical components. Replace the parts or mask it
with insulation tapes if moisture intrusion was
confirmed.
10. Do not touch the icemaker with hands or tools to
confirm the operation of geared motor.
11. Do not let the customers repair, disassemble, and
reconstruct the refrigerator for themselves. It may
cause accident, electric shock, or fire.
12. Do not store flammable materials such as ether,
benzene, alcohol, chemicals, gas, or medicine in the
refrigerator.
13. Do not put flower vase, cup, cosmetics, chemicals,
etc., or container with full of water on the top of the
refrigerator.
14. Do not put glass bottles with full of water into the
freezer. The contents shall freeze and break the glass
bottles.
15. When you scrap the refrigerator, please disconnect the
door gasket first and scrap it where children are not
accessible.

2. How to Install Water Pipe
■Before Installation
1. The icemaker requires the water pressure of 1.5 -
8.5kgf/cm2. (It is acceptable if city water fills a cup of
180cc with water for 3 seconds)
2. Install booster pump where the city water pressure is
below 1.5kgf/cm2for normal operation of water and ice
dispenser.
3. The total length of water pipe shall be less than 12m. Do
not bend the pipe at right angle. If the length is more
than 12m, there will be troubles on water supply due to
water pressure drop.
4. Please install water pipe where there is no heat around.
2-1. When connecting directly to the water tap.
■Please confirm the following installation parts.

3. When customer uses bottled water.
*If customer wants to use bottled water, extra pump should be installed as shown below.
1. The pump system should not be on the floor (it may cause noise and vibration). Securely fasten the inlet and outlet
nuts of pump.
2. If there is any leakage after installation, cut the water tube at right angle and reassemble.
3. When put the water tube end into the bottle, leave a clearance between bottle bottom and water tube end.
4 Check water coming out and any leakage.
Caution : • If feed tube is more than 4m, less water will come out due to pressure drops.
• Use standard feed tube to prevent leaking.
■Outternal Filter
1. Filter Fixation
1) There are two types of filter. One is nut type and the other is connector type.
2) Connect feed tube to the filter outlet and water valve connecting tube.
3) Fix the filter at proper place around the sink where it is easy to replace the filter and to receive the cleaning water.
Please consider the length of tube shall be less than 8m when locating filter.
2. Filter Cleaning
1) Connect feed tube to the inlet of feed valve and filter.
2) Clean the main valve and feed valve with water for at
least one minute until clean water comes out.

■Install Water Filter (Applicable to some models only)
■Before Installing water filter
1. Before installing the filter, take out the top shelf of the
refrigerator after tilting it to the direction (a) and lifting it
to the direction (b) and move it to the lower part.
2. Remove the lamp cover by pressing the protrusion
under the cover and pulling the cover to the front.
■Installing water filter
1. Initial installation of water filter
Remove the filter substitute cap by turning it
counterclockwise (a) by 90 degrees and pulling it down.
Note : Keep it safe to use it later when you do not use the
filter.
Remove the red cap from the filter and attach the
sticker. Insert the upper part of the filter (a) after
aligning with the guideline marked on the control box,
and fasten it by turning it clockwise by 90 degrees.
Note : Check that the guideline and the fastening
indication line are aligned.
2. Replacement of water filter
While holding the lower part of the filter, turn it
counterclockwise (a) by 90 degrees and pull it down.
Note : Check that the guideline and the loosening
indication line are aligned.
■After installing water filter
Reassemble the lamp cover and the top shelf of the
refrigerator. To place the top shelf of the refrigerator, raise
the front part of the shelf a bit so that the hook of the shelf
is fit into the groove.
In order to clean the water filter system, drain water for
about 3 min.
Note : Then open the door of the refrigerator and check for
water droppings on the shelf under the filter.

3. How to Control the Amount of Water Supplied to Icemaker.
3-1. Confirm the amount of water supplied to the icemaker.
1. Remove the cover bucket : Lift the cover with a slight twisting.
2. Remove the ice bucket : Lift the lower part slightly and take the ice bucket out slowly.
• Caution : • Do not put your hands or tools into the
chute to confirm the operation of geared
motor. It may damage refrigerator or hurt
your hands.
• Check the operation of motor with its operation
noise.
3. Apply electricity after connecting water pipe.
1) Press test switch under the icemaker for two seconds as shown below.
2) The bell rings(ding~dong) and ice tray rotates and water comes out from the icemaker water tube.
3) The water shall be supplied two or three times into the tray. The amount of water supplied for each time is small.
Put a water container under the ice tray and press test switch.
4) When ice tray rotates, the water in it will spill. Collect the spilt water and throw away into the sink.
5) When ice tray has finished rotation, water comes out from the water tube. Confirm the amounts of water in the ice tray.
(refer to fig. The optimum amount of water is 80cc)
* It is acceptable if the adjusted level of water is a bit smaller than maximum level.

3-2. Control the amount of water supplied to the icemaker.
Caution : • Please unplug the power cord from the wall outlet and wait for more than three minutes before disconnecting
PCB cover as 310V is applied in the control panel.
1. Disconnect PCB cover from the upper part of the refrigerator.
2. Adjust the amount of water supplied by using DIP switch.
■Water Supplying Time Control Option
1) The water supplying time is set at 4.5 seconds when the refrigerator is delivered.
2) The amount of water supplied depends on the setting time and water pressure (city water pressure).
3) If ice cube is too small, increase the water supplying time. This happens when too small water is supplied into the ice tray.
4) If ice cube sticks together, decrease the water supplying time. This happens when too much water is supplied into the ice tray.
Caution : When adjusting the amount of water supplied, adjust step by step. Otherwise the water may spill over.
3. When adjustment of control switch for the amount of water supplied is complete, check the level of water in the ice tray.
