1. WARNINGS AND PRECAUTIONS FOR SAFETY

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 PCB 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.

5. Control way of Error (if any)

1) “F1” error
Cause : F-sensor disconnection or shor t

Check point : Measure the resistance between both terminals after separating CN8 (or CN15)

If F-sensor is disconnected or shorted , change the F-sensor in the freezer compartment.

How to reset : If F-sensor is normal, the error is terminal temperature.

2) “R1” error

Cause : R-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN7 (or CN14)

If R-sensor is disconnected or shorted , change the F-sensor in the refrigerator compartment.
How to reset : If R-sensor is normal, the error is terminal temperature.

3) “rt” error

Cause : RT-sensor disconnection or short (full down)
Check point : Measure the voltage of “A”part on the Main PCB.

If the voltage is 0.5V~4.5V, it is normal.

11-4. Water Line Installation

How to install Water Line

1.The water pressure should be 3 kgf /cm2 or more t o run t h e
automatic icemaker.

※Checkup your tap water pressure ; if a cu p of 1 8 0cc is full

within 10 seconds, the pressure is OK.

2.When installing the water tubes, ensure they are not close to
Any hot surface.

3.The water filter only “filters” water ; it does not eliminate any
bacteria or microbes.

4.If the water pressure is not so high to run the icemaker, call the
local plumber to get an additional water pressure pump.

5.The filter life depends on the amount of use. We recommend
you replace the filter at least once every 6months.
※When attaching the filter, place it for easy access (removing

& replacing)

6.After installation of refrigerator and water line system, select
[WATER] on your control panel and press it for 2~3 minutes to
supply water into the water tank and dispense water.

7.Use sealing tape to every connection of pipes/tubes to ensure
there is no water leak.

8.The water tube should be connected to the cold water line.

Installation Procedure

1. Join connector to water tap

2. Get ready to install water line

1) Measure an approximate distance between the filter and the
Water Tube and cut the tube off filter vertically.

2) Connect the tubes to the filter as the figure shows.

Leave a sufficient distance when cutting the tubes.

82

3. Remove any substance from filter

1) Open the main tap water valve and check if water comes out of
the Water Tube.

2) Check if the Water Valve is open in case water does not come out.

3) Leave the valve open until clean water is coming out.
※Initial water may contain some substances ou t of filter

(manufacturing process).

4. Attach the filter box

1)Screw and fasten the filter holder to the left/right side of the back of
refrigerator.

※In case the holder is not fastened well, remove the back paper

of the tape on the filter holder and attach it.

2)Insert the filter box into the holder.

5. Connect water tube

2)

Insert the fastening ring into the Water tube.

(Be careful to follow the direction of the nut.)

3)Insert the Water Tube into the top of Water Valve, turn the nut
clockwise to fasten it. (The Water valve is to the right of the motor.)

4)Check for any bent tubes or water leaks; if so, re-check installation
procedure.

5)Replace the rear cover. (The Water Tube should be placed
between the groove of the refrigerator back and motor cover.)

Set the tube upright as the figure shows.

6. Fasten water tube

1) Fasten the Water Tube with the [Fastener A] .

2) Check if the tube is bent or sqeezed. If so, set it right to

prevent any water leak.

7. After installation

1) Plug the refrigerator, press the [WATER] button on the control

panel for 2~3 minutes to remove any air (bubble) in the pipes
and drain out the initial water.
