INSTALLATION
ENGLISH
CAUTION
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 276~827
kPa or 2.8~8.4 kgf/cm² on models with a water
filter.
If a reverse osmosis water filtration system is
connected to the 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 the 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/
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
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,
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, you will need
an adapter (available at plumbing supply
stores) to connect the water line to the
refrigerator OR you
can cut off the flared
fitting with a tube
cutter and then use a
compression fitting.
•
Shutoff valve
to connect to the cold
water line. The shutoff valve should
have a water inlet with a minimum
inside diameter of 5/32 in. at the point of
connection to the COLD WATER LINE.
Saddle-type shutoff valves are included
in many water
supply kits. Before
purchasing, make
sure a saddle-type
valve complies with
your local plumbing codes.
NOTE
A self piercing saddle type water valve
should not be used.
