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.
CAUTION
To prevent burns and product damange,
only connect the fridge water line to a
cold water supply.
If you use your fridge before connecting the
water line, make sure the icemaker power
button is turned off.
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. If the fridge is installed in an area with
low water pressure (below 20 psi), you can
install a booster pump to compensate for the low
pressure.
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 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).
CAUTION
Wear eye protection during installation
to prevent injury.
If the water pressure from the reverse osmosis
system is less than 20 psi or 138 kPa or 1.4 kgf/
cm² (takes more than 4.0 sec to fill a cup of 7 oz
or 198 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
osmosis system to refill after heavy
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.
