Connecting the Water Line

Before Beginning

This water line installation is not covered by the
refrigerator warranty. Follow these instructions
carefully to minimize the risk of expensive water
damage.
If necessary, call a qualified plumber to correct water
hammer before installing the water supply line to
the refrigerator. Water banging in the pipes, or water
hammer in residential plumbing can cause damage
to refrigerator parts and lead to water leakage or
flooding.
• Turn the icemaker OFF if the refrigerator will be
used before the water line is connected.
• Do not install the icemaker tubing in areas where
the ambient temperatures fall below freezing.
WARNING
• Connect to potable water supply only.
CAUTION
• To prevent burns and product damage, only
connect the refrigerator water line to a cold water
supply.
• Wear eye protection during installation to prevent
injury.

Water Pressure

The water pressure must be 20-120 psi or
138-827 kPa or 1.4-8.4 kgf/cm² on models without a
water filter and 40-120 psi or 276-827kPa or 2.8-8.4
kgf/cm² on models with a water filter.
If a reverse osmosis water filtration system is
connected to your cold water supply, this waterline
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 (276-414 kPa or
2.8-4.2 kgf/cm², less than 2.0-3.0 sec. to fill a cup of 7
oz or 198 cc capacity).
If the water pressure from the reverse osmosis
system is less than 20 psi or 138 kPa or 1.4 kgf/ cm
(takes more than 4 seconds to fill a cup of 7 oz or
198 cc 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 water pressure remains low, call a licensed,
qualified plumber.
• All installations must be in accordance with local
plumbing code requirements.
Supplies Needed
• Copper or PEX Tubing, ¼ in. 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 in. [25 cm]
diameter) to allow the refrigerator to move out from
the wall after installation.
• Power drill.
• ½ in. or adjustable wrench.
• Flat-blade and Phillips-head screwdrivers.
• Two ¼ in. outer diameter compression nuts and
2 ferrules (sleeves) to connect the copper tubing to
the shutoff valve and the refrigerator water valve.
• If your existing copper water line has a flared fitting
at the end, purchase an adapter (available at
plumbing supply stores) to connect the water line
to the refrigerator OR cut off the flared fitting with a
tube cutter and then use a compression fitting.
