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.
78
10-4. 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.
79
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.
