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
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.
83
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 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.
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.
