Connecting the Water Line
Before You Begin
This water line installation is not covered by
the fridge 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 fridge
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
fridge.
If you use your fridge before connecting the
water line, make sure the icemaker power
switch is in the OFF (O) position.
Water Pressure
A cold water supply. The water pressure must
be between 20 and 120 psi (140 and 830 kPa) on
models without a water filter and between 40 and
120 psi (280 and 830 kPa) 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 fridge
warranty. Follow the following 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 and 60 psi (280 and 420 kPa),
less than 2.0~3.0 sec. to fill a cup of 7 oz (200 cc)
capacity.
If the water pressure from the reverse osmosis
system is less than 21 psi (145 kPa) (takes more
than 4.0 sec to fill a cup of 7 oz (200 cc) capacity):
Check to see if the sediment filter in
y
the reverse osmosis system is blocked.
Replace the filter if necessary.
Allow the storage tank on the reverse
y
usage.
If the issue concerning water pressure
y
from reverse osmosis remains, call a
licensed, qualified plumber.
All installations must be in accordance
y
with local plumbing code requirements.
What You Will Need
Copper Tubing, y
¼ in. outer diameter, to
connect the fridge to the water supply.
Be sure both ends of the tubing are cut
square.
To determine how much
y
tubing you need: measure
the distance from the
water valve on the back of the fridge 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 3
turns of about 10 in. [25 cm] diameter)
to allow the fridge to move out from the
wall after installation.
Power drill. y
½ in. or adjustable y
wrench.
Flat blade and Phillips
y
head screwdrivers.
Two ¼ in. outer diameter
y
compression nuts and
2 ferrules (sleeves)
to
connect the copper tubing to the shutoff
valve and the fridge water valve.
CAUTiON
Do not install the icemaker tubing in
areas where temperatures fall below
freezing.
CAUTiON
To prevent burns and product damange,
only connect the fridge water line to a
cold water supply.
