11-3. Refrigerator Leveling & Door Adjustment

In case freezer 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)

※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.)

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.

Caution

In case refrigerator door is lower

than refrigerator door

82

11-4. Water Line Installation

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.

How to install Water Line

1. Join connector to water tap

Installation Procedure

2. Get ready to install water line
