18. Installation of the water dispenser line

1) For automatic operation of the ice maker, water pressure of 1.4~4.5Kg

is required.(It is

acceptable if the disposable paper cup(177cc) can be filled up with water within a second.)

2) The water tube can be used by cutting to the desired length. Make sure that the tube is not

bent.

3) Make the maximum length of the water tube to be 12m, if possible. If the length is over 12m,

it will cause a problem to supply water because of decrease of water pressure.

4) Locate the water tube at the area without heat.

5) The purifier is just for filtration. It will not work as sterilizer of microorganisms.

6) If the refrigerator is installed in the area with low water pressure(below 1.4 Kg

additionally purchased booster pump may be installed in order to compensate the shortage

of pressure.

7) The life cycle of purifier depends upon the condition of the usage, but we recommend that

you change it every 6 months. So we recommend to install it at an eccess place for changing.

8) To supply water to the storage tank inside the refrigerator, press the cold water button for

about 2 or 3 minutes and make cold water drop from the cold water outlet.

9) In order to avid possible leakage, seal every joined area using sealing tape.

10) The water tube should be commected to the cold tap water.

Check the components

1. Connect couplers and valve to the water pipe.

1) Close the main water valve.

2) Connect the coupler ÒAÓ to the tap water valve.

3) Connect the coupler ÒAÓ and ÒBÓ to the water pipe.

4) Every joint should be taped with sealing tape.(see the picture)

5) If there is only one water pipe, connect coupler ÒAÓ

If the coupler A and B doesnÕt fit to the existing water pipe, consult the closest authorized service dealer and purchase the right couplers for the proper installation.

2. Connect the water tube to water tube valve

1) Insert the nut into the water tube

2) Insert the water tube into the water tube valve as shown in the picture on the right side.

3) Tighten the nut by turning it.

The water tube should be connected to the cold water pipe. If it is connected to the hol water pipe, it may cause some problems in the Functioning of the purcher.

PRECATUTION!

6. Fix the purifier.

1) Fix the purifier as shown int he picture on the right.

3. Select the purifier location for installation

1) Cut the water tube, attached to the purifier, to the proper length after measuring the distance from the location of the purifier to the water tube valve.

2) If you want to reassemble the water inlet side and outlet side of the purifier during the installation of the purifier, see the reference picture.

4. Remove the residuals inside the purifies.

1) Open the main water valve to check whether water is running through the water tube from the water inlet side of the purifier.

2) If water doesnÕt come out through the tube, turn the water tube valve.

3) Leave the faucet open until clean water is running out.

4) It is no problem with the residuals because it might be left while manufactruing the filter.

5. Fix the purifier lock station.

1) Hold the purifier lock station against the lock hole of rightlower side in the back of the refrigerator and fix it tightly using screw.

7. Connect the water tube to the refrigerator.

1) Remove the back cover of the refrigerator.

2) Connect the water tube to the valve through the hole in the back cover as shown in the picture.(The connector is lockated at right side of the machine room in the back of the refrigerator.)

3) When connected, check whether there is any leakage. On leakage, reassemble them.

8. Put the water tube in order

1) Using the clip ÒAÓ and ÒBÓ fix the water tube to the wall.

2) When the water tube is put in order, make sure there are any forced bending and pushing against the water tube.

WATER TUBE

9. Complete the installation of the water dispenser line

1) Turn on the refrigerator and press the left side lever until water is coming out through the water tube.(approximately 2~3minute) (Press it until the initial air outing phenomenon disappear.)

2) At this time, check any possible leakage on the joints of the water tube. After putting the water tube in order, move the refrigerator to the desired location. Once the refrigerator is located, do not move the refrigerator as possible.

10. Check the amount of supplied water to the ice maker.

1) Remove the upper ice maker frome the refrigerator.

The Method to control the amount of water supply to the ice maker

1. Disassemble the PCB panel at the top of he refrigerator.

3. If S/W control is completed, check the amount of supplied water to the Ice Maker.

4. If the amount of water supply is not enough, reset the S/W. (Read item 2 and 3). If the setting is completed in accordance with water pressure in the pipe, reassemble the PCB panel.

2. Using the water controlling S/W, control the amount of water supply.

Option to control water-supply time

2) When the test button is pressed, the ice cube container is tured and then water is out from the tap of the ice maker where water is wupplied. At this time, check the amount of water.(see the picture) If there is over-supply of water, the ice cube will be made in attached form of 2 to 4 ice cubes, If there is less-supply of water, the ice cube will be made in small size. When this happens, you may encounter inconvenience while using. This is not a problem in the refrigerator. It is the problem of water pressure in the water pipe and occurs frequrently. When this problem occurs, control the amount of water supply by the following method.

SWITCH NO MODEL NAME

After change of the water-supply time, the power switch of the refrigerator must be turned off and then turned on again. (Otherwise, the change will not work.) When the refrigerator is marketed, the water-supply time is set to 6 seconds. The amount of water supply depends upon the set time and the water pressure(water pressure for home use). If th ice cube is small, it may be caused by less supply of water. So, increase the watersupply time(for example : change the time from 6 seconds to 7 seconds). If ice cubes are attached each other because of over-supply of water, decrease the water-supply time(for example : change the time from 6 seconds to 5 seconds).

If the controlled amount of water supply is slightly below the optimum level, it doesnÕt matter for use.

Notice

When setting the amount of water supply, do not select the large amount of water supply from the beginning. Set step-by-step. (Water can be over flowed)
