Connecting the Water Line
Before You Begin
This water line installation is not covered by the refrigerator war- ranty. 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 can lead to water leakage or flooding. Call a qualified plumber to correct water hammer before installing the water supply line to the refrigera- tor.
CAUTION
To prevent burns and product damange, only con- nect the refrigerator water line to a cold water supply.
If you use your refrigerator before connecting the water line, make sure the icemaker power switch is in the OFF (O) position.
CAUTION
Do not install the icemaker tubing in areas where temperatures fall below freezing.
Water Pressure
A cold water supply. The water pressure must be between 20 and 125 psi on models without a water filter and between 40 and 125 psi on models with a water filter.
If a reverse osmosis water filtration system is connected to your cold water supply, this water line installation is not covered by the refrigerator warranty. Follow the following 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 (2.8 kgf/cm2 ~ 4.2 kgf/cm2, less than 2.0~3.0 sec. to fill a cup of 7 oz capacity).
CAUTION
Wear eye protection during installation to prevent injury.
If the water pressure from the reverse osmosis system is less than 21 psi or 1.5 kgf/cm2 (takes more than 4.0 sec to fill a cup of 7 oz capacity):
yCheck to see if the sediment filter in the reverse osmo- sis system is blocked. Replace the filter if necessary.
yAllow the storage tank on the reverse osmosis system to refill after heavy usage.
yIf the issue concerning water pressure from reverse osmosis remains, call a licensed, qualified plumber.
yAll installations must be in accordance with local plumb- ing code requirements.
What You Will Need
yCopper Tubing, ¼ in. outer diameter, to connect the refrigerator to the water supply. Be sure both ends of the tubing are cut square.
yTo determine how much tubing you need: measure the distance from the water valve on the back of the refrig-
erator 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 al- low the refrigerator to move out from the wall after instal- lation.
y Power drill.
y ½ in. or adjustable wrench.
y Flat blade and Phillips head screwdrivers.
y 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.
yIf 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.
yShutoff valve to connect to the cold water line. The shutoff valve should have a water inlet with a minimum inside di- ameter of 5/32 in. at the point of connection to the COLD WATER LINE.
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.
