Water Pressure - LG LSXC22486 Series Owner's Manual

18 INSTALLATION
CAUTION
• To prevent burns and product damage, only
connect the refrigerator water line to a cold
water supply.
• Wear eye protection during installation to
prevent injury.

Water Pressure

You will need a cold water supply.
Water Pressure
Models with out
water filter
Where reverse
osmosis water
filtration system is
connected to a cold
water supply
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.
20 - 120 psi (138 - 827 kPa)
40 - 60 psi minimum to
reverse osmosis system (2.8
kgf/cm2 - 4.2 kgf/ cm2, or
less than 2 - 3 seconds to fill
a cup of 7 oz capacity)
• 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.
