5. Control way of Error (if any)
1) “F1” error
Cause : F-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN8 (or CN15)
of the Main PCB. (Refer to the 5-2.)
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)
of the Main PCB. (Refer to the 5-2.)
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.
If the voltage is 0V (short) or 5V (disconnected), change the RT-sensor on the Main PCB
How to reset : If RT-sensor is normal, the error is terminated automatically.

6) “C1” error
Cause : in case comp. works for over 3 hours when D-sensor temp. is over -5℃
Check point : Refrigerant leakage.
7) “F3” error
Cause : in case defrosting return is done by time limit of 80 min
Check point : Measure the resistance between both terminals of the defrost heater.

REMARKS

9) “EI”ERROR
Cause : I-SENSOR disconnection / short
Check point : Measure the resistance between both terminals after separating CN11
of the Main PCB. (Refer to the 5-2.)
If F-sensor is disconnected or shorted , change the I-sensor in the automatic ice maker.
10) “EF” ERROR
Cause : When Flow-sensor ERROR (There is no Pulse during some time)
The number of pulse signal is below 10 by 1 sec during water supply.
Check point : Water supply line
11) “Eg” ERROR
Cause : I-sensor temp (5min after water supply) doesn’t go up.
Check the I-sensor or water supply line.
12) “ES” error (MICRO switch error)
Cause : When it senses 1min continuously
Check the MICRO switch of the dispenser.

13) “Ea” error
Cause : Malfunction of ice drop motor.
Check the motor by pushing test switch.
14) “Eu” error
Cause : Switch (which senses if the ice is full or not) is in error.
Control : When dropping the ice, the motor just rotates 90 degree.
Termination : When the switch is in normal.

15)“EA“ ERROR
Cause : When sensing Ice dropping by time 3 times in level sensor SW Error.
Control : Stop of Ice Maker
Termination : With normal level switch.
Re-input of power or push if icemaker test switch.

more certain to do like this.)

4.Refrigerant charging.

* Charging sequence
1)
Check the amount of refrigerant supplied to each model after
completing vacuum degassing.
2) Evacuate bombe with a vacuum pump.
3) Measure the amount of refrigerant charged.
- Measure the weight of an evacuated bombe with an electronic scale.
- Charge refrigerant into a bombe and measure the weight. Calculate
the weight of refrigerant charged into the bombe by subtracting the
weight of an evacuated bombe.
Indicate the weight of
an evacuated bombe

※ KEYPOINTING
1) Be sure to charge
the refrigerant at
around 25°C.
2) Be sure to keep
-5g in the winter
and +5g in summer.

Calculation of amount of refrigerant charged
the amount of refrigerant charged
= a weight after charging
- a weight before charging
(a weight of an evacuated cylinder)

11-3. Refrigerator Leveling & Door Adjustment
※Refrigerator must be level in order to maintain optimal performance and desirable front appearance.
(If the floor beneath the refrigerator is uneven, freezer and refrigerator doors look unbalanced.)

In case freezer door is lower
than refrigerator door

In case refrigerator door is lower
than refrigerator door

Insert a screw driver (flat tip) into a groove of the
left wheel (bottom of freezer) and turn it clockwise
until the door is balanced.
(clockwise to raise freezer door ;
counterclockwise to lower)

Caution

Insert a screw driver (flat tip) into a groove of the
right wheel (bottom of refrigerator) and turn it
clockwise until the door is balanced.
(clockwise to raise refrigerator door ;
counterclockwise to lower)

The front of refrigerator needs to be higher just a little than the back for easy
door closing, but if the wheel is raised too much for door balance, i.e. front of
refrigerator is too higher than the back, it can be difficult to open the door.

11-4. Water Line Installation
How to install Water Line
1.The water pressure should be 3kgf/cm2 or more to run the
automatic icemaker.
※Checkup your tap water pressure ; if a cup of 180cc 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.

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
