Connecting The Water Line - LG MFL37933590 Owner's Manual

BEFORE YOU BEGIN
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.
To prevent 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 power switch is
in the O (off) position.
Do not install the icemaker tubing in areas where
temperatures fall below freezing.
When using any electrical device (such as a power
drill) during installation, be sure the device is
double- insulated or grounded in a manner to
prevent the hazard of electric shock, or is battery-
powered.
If a reverse osmosis water filtration system is
connected to your cold water supply, This water
line installation is not warranted by the refrigerator
or icemaker manufacturer.
Follow next 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/cm
4.2 Kgf/cm 2 , less than 2.0~3.0sec to fill a cup of 7oz
capacity).
If the water pressure from the reverse osmosis
system is less than 21 psi (1.5 Kgf/cm
4.0sec to fill a cup of 7oz capacity):
Check to see whether 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 issue about water pressure from reverse
osmosis remains, call a licensed, qualified plumber.
All installations must be in accordance with local
plumbing code requirements.
NOTE: Wear eye protection.
For installation, hose set will be provided with the
refrigerator. When reinstalling, the hose must be
discarded and replaced with a new one.

CONNECTING THE WATER LINE

2 ~

WHAT YOU WILL NEED
• Copper Tubing,
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≤ [25 cm] diameter) to
allow the refrigerator to move out from the wall
after installation.
• A cold water supply. The water pressure must
be between 147-834 kPa on models without a
water filter and between 280-834 kPa on
models with a water filter.
• Power drill.
• 1/2≤ ≤ or adjustable
wrench.
• Straight- and
Phillips-blade
screwdriver.
• Two 1/4≤ ≤ 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, 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.
• 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≤ 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.
