system.

Open compressor motor winding.

Too low AC voltage supplied to the Inverter.

Demagnetized rotor
(only if compressor was previously

connected
directly to the AC power supply).

- Malfunction during operation

ACTIONPROBLEM

Verify the Compressor Cable connection.Compressor disconnected from the Inverter

Verify the AC Input Cable connection and measure the AC Input voltage.

Verify the Control Input Cable connection and measure the signal from the
Main-PCB.

Return the unit to manufacturer, replacing it by a new one.Blown fuse (due to previous major failure).

Measure winding for open circuit between all pair of pins on the hermetic terminal.
If one winding is open, replace it by a new one.

Wait the necessary time or reset the Inverter disconnecting it from the
AC power supply. The reset time is about 15s.

Replace compressor by a new one and test for confirmation.

Allow the Inverter to equalize pressure between suction and discharge sides.

Measure winding for open circuit between all pair of pins on the hermetic
terminal. If one winding is open, replace it by a new one.
Measure AC voltage to confirm; correct the voltage or change the Inverter
to the correct voltage range (115V or 220V model).

Replace compressor by a new one and test for confirmation.

Compressor does not run at the speed
selected by the Inverter.

ACTIONPROBLEM

Too high compression load, with compressor being subjected to a stall
condition. (lower suction and/or discharge pressures for correction).

Too low AC voltage. Check the AC voltage supplied to the Inverter and set it
to the required level or change the Inverter to the correct voltage range.
(115V or 220V model).

No or incorrect control signal.
(check if the correct control signal is arriving at the control Input Connection).

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 cup 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 6 months.
※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

Place the rubber washer inside the tap connector and

screw onto the 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.

76

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 out 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

1)Remove the rear cover at the bottom back of the refrigerator.

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 squeezed. 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.

2) Check the water leak again through the water supply system

(tubes, connectors and pipes) Rearrange the tubes again
and do not move the refrigerator.
