Installing the water line.
Read these instructions completely and carefully.

Before You Begin
When connecting a GE Reverse Osmosis Water System to your refrigerator, the only
approved installation is with a GERVKIT.
If the water supply to the refrigerator is from a Reverse Osmosis Water Filtration System
AND the refrigerator also has a water filter, use the refrigerator's filter bypass plug. Using
the refrigerator's water filtration cartridge in conjunction with the RO filter can result in hol-
low ice cubes and slower water flow from the water dispenser.
This water line installation is not warranted by the refrigerator or icemaker manufacturer.
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 lead to water leakage or flooding. Call a qualified plumber
to correct water hammer before installing the water supply line to the refrigerator.
Toprevent burns and product damage, do not hook up the water line to the
hot water line.
If you use your refrigerator before connecting the water line, make sure the
icemaker feeler arm is kept in the STOP (up) position.
Do not instafl the icemaker tubing in areas where temperatures fail below freezing.
When using any electrical device (such as a power drill) during installation, be sure
the device is insulated or wired in a manner to prevent the hazard of electric shock.
All installations must be in accordance with local plumbing code requirements.
What YouWill Need
To determine how much copper 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 (244 cm). Be sure there is sufficient extra tubing
[about 8 feet (244 cm) coiled into 3 turns of about 10 inches (25 cm) diameter] to allow
the refrigerator to move out from the wall after instaflation.
A watersupply kit (containing copper tubing, shutoffvalve and fittings listed below) is reTail-
able at extra cost fi'om your dealer or fi'om Parts and Accessories, 800-626-2002.
Cold watersupply. The water pressure must be between 20 and 120 p.s.i. (1.4-8.2 bar) on
models _dthout a water filter and between 40 and 120 p.s.i. (2.8-8.2 bar) on models _dth
a water filter.
Powerdrill.
Coppertubing, 1 /4" outer diameter to connect the refiigerator to the water supply. Be sure
both ends of the robing are cut square.
Do not use plastic tubing or plastic fittings because the water supply line is under
pressure at all times. Certain types of plastic tubing may become brittle with age and
crack, resulting in water leakage.
Two1/4" outerdiametercompression nutsand2 ferrules(sleeves) to connect d_e copper
tubing to the shutoffvalve and the refiigerator water valve.
If your existing water line has a flared fitting at tim end, you xdll need an adapter(mTailableat
plumbing supply stores) to connect the water line to the refiigerator ORyou can cut offthe
flared fitting,_dth a tube cutter and then use a compression fitting.
Shutoff valve to connect
to the cold water line. The shutoffvalve should have a water inlet
,_dfl_ a minimum inside diameter of 5/32" at tim point of connection to tim COLD WATER
LINE. Saddle-bq)e shutoffvalves are included in many water supply kits. Befiore purchasing,
make sure a saddle-bq)e valve complies,_dfll your local plumbing codes.
