INSTALLATION 27
Connecting the Wafer Line
Before You Begin
This water line installation is not covered by the
refrigerator warranty. Follow these instructions
carefully to minimize the risk of expensive water
damage.
Water hammer (water banging in the pipes) in
house plumbing can cause damage to refrigerator
parts and can lead to water leakage or flooding.
Call a qualified plumber to correct water hammer
before installing the water supply line to the
refrigerator.
_ Z_ CAUTION
To prevent burns and product damage,
only connect the refrigerator water line to
a cold water supply.
If you use your refrigerator before connecting
the water line, make sure the icemaker power
switch is in the OFF (O) position.
-Z_ CAUTION -,
Do not install the icemaker tubing in
areas where temperatures fan below
. freezing
Water Pressure
The water pressure must be between 20 and 120
psi on models without a water filter and between
40 and 120 psi on models with a water filter.
If a reverse osmosis water filtration system is
connected to your cold water supply, this water
line installation is not covered by the refrigerator
warranty. Follow the instructions carefully to
minimize the risk of expensive water damage.
If a reverse osmosis water filtration system is
connected to your cold water supply, the water
pressure to the reverse osmosis system needs to
be a minimum of 40 to 60 psi (2.8 kgf/cm 2 ~ 4.2
kgf/cm 2, less than 2.0~3.0 sec. to fill a cup of 7 oz
capacity).
--Z_ CAUTION -_
Wear eye prc)tection during installation
If the water pressure from the reverse osmosis
system is less than 21 psi or 1.5 kgf/cm _ (takes
more than 4.0 sec to fill a cup of 7 oz capacity):
• Check to see if the sediment filter in
the reverse osmosis system is blocked.
Replace the filter if necessary.
• Allow the storage tank on the reverse
osmosis system to refill after heavy
usage.
• if water pressure issues associated with
a reverse osmosis system persist, can a
licensed, qualified plumber.
• All installations must be in accordance
with local plumbing code requirements.
What You Will Need
Copper Tubing, 1A in, outer diameter, to
connect the refrigerator to the water
supply. Be sure both ends of the tubing
are cut square.
To determine how JJ
much tubing you need:
measure the distance
from the water valve on the back of the
refrigerator to the water supply pipe.
Then, add 8 feet (2.4 m).
Be sure there is sufficient extra tubing
(about 8 feet [2.4 m] coiled into three
turns of about 10 in. [25 cm] diameter)
to allow the refrigerator to move out
from the wan after installation.
Power drill.
* 1/2 in. or adjusfable
wrench.
. Flat blade and Phillips
heed screwdrivers.
* Two 1¼ in. outer
dlame_er compression
nu|s and 2 ferrules (sleeves) to connect the
copper tubing to the shutoff valve and
the refrigerator water valve,
