ENGLISH 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 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. INSTALLATION 23 ••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. Water Line Installation Instructions WARNING Electric Shock Hazard: ••When using any electrical device (such as a power drill) during installation, be sure the device is battery-powered, double-insulated or grounded in a manner that will prevent the hazard of electric shock. Install the shutoff valve on the nearest frequently used drinking water line. 1 Shut off the main water supply. Turn on the nearest faucet to relieve the pressure on the line. ••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. 2 Choose the valve location. Choose a location for the valve that is easily accessible. It is best to connect into the side of a vertical water pipe. When it is necessary to connect into a horizontal water pipe, make the connection to the top or side, rather than at the bottom, to avoid drawing off any sediment from the water pipe.

INSTALLATION
ENGLISH
If the water pressure from the reverse osmosis
system is less than 20 psi or 138 kPa or 1.4 kgf/ cm
2
(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.
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.
Water Line Installation Instructions
WARNING
Electric Shock Hazard:
When using any electrical device (such as a
power drill) during installation, be sure the device
is battery-powered, double-insulated or grounded
in a manner that will prevent the hazard of
electric shock.
Install the shutoff valve on the nearest frequently
used drinking water line.
1
Shut off the main water supply.
Turn on the nearest faucet to relieve the pressure
on the line.
2
Choose the valve location.
Choose a location for the valve that is easily
accessible. It is best to connect into the side of
a vertical water pipe. When it is necessary to
connect into a horizontal water pipe, make the
connection to the top or side, rather than at the
bottom, to avoid drawing off any sediment from
the water pipe.
