LG GS73SGS - Water Line Installation Instructions

18 INSTALLATION
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 ll a cup of 7 oz or
198 cc capacity):
• Check to see if the sediment lter in the reverse
osmosis system is blocked. Replace the lter if
necessary.
• Allow the storage tank on the reverse osmosis
system to rell after heavy usage.
• If the water pressure remains low, call a licensed,
qualied 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 sufcient 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 ared tting
at the end, purchase an adapter (available at
plumbing supply stores) to connect the water line
to the refrigerator OR cut off the ared tting with a
tube cutter and then use a compression tting.
• 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.
