Connecting the Water 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.
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.
CAUTION
Do not install the icemaker tubing in areas
where temperatures fall 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
kgf/cm , less than 2,0~3,0 seconds to fill a cup of 7
2
oz capacity).
CAUTION
Wear eye protection during installation to
prevent injury.
If the water pressure from the reverse osmosis
system is less than 21 psi or 1,5 kgf/cm
than 4,0 seconds 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 the issue concerning water pressure from
reverse osmosis remains, call a licensed, qualified
plumber.
All installations must be in accordance with local
plumbing code requirements.
What you will need
Copper Tubing, 1/4 inch (6,35 mm) outer diameter,
to connect the refrigerator to the water supply. Be
sure both ends of the tubing are cut square.
To determine how 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 3 turns of about 10 inch [25 cm] diameter) to
allow the refrigerator to move out from the wall
after installation.
Power drill.
1/2 inch (12,7 mm) or adjustable
wrench.
Flat blade and Phillips head
screwdrivers.
Two 1/4 inch (6,35 mm) outer
diameter compression nuts and 2 ferrules
(sleeves) to connect the copper tubing to the
shutoff valve and the refrigerator water valve.
