CONNECTING THE WATER LINE

NOTE: It is necessary to have a water source when both

water and/or ice dispensers are available in your product.

BEFORE START

The water source is not guaranteed by the refrigerator

manufacturer. Follow instructions carefully in order to

reduce damage.

Air located inside the water pipes can cause hammering

or tapping causing damage to the inner pipes or water

spillage in the inside of the refrigerator. Call a qualified

plumber to fix such hammering on the connections

before installing the water pipe.

To avoid burn damage or such, never connect refrigerator

to hot water pipes.

If you are to use the refrigerator before connecting it

to the water source, make sure the ice maker is the off

position.

Never attempt to install the ice maker pipes in areas

where room temperature is below freezing point.

When using any electrical device (like a drill) during

the installation, make sure device is doubly isolated or

making ground to prevent risk of electrical surge or

discharge.

All installations should be done considering local water

and drainage requirements.

• If an inverted osmosis water filtration system is

connected to the cold water source, the water hose

installation is not assured or guaranteed by the

refrigerator or automated ice maker manufacturer.

Follow the next instructions carefully to minimize costly

water related damages.

• When having an inverted osmosis water filtration

system connected to the cold-water flow, the water

pressure for such system must be at least between

40-60 PSI or 0,27 MPa (2,8 kg · f / cm ² ~ 4,2 kg · f

/ cm ², (2,8 kg · f / cm ² ~ 4,2 kg · f / cm ², less than

2 ~ 3 seconds to fill a 7 oz of capacity cup [0,2 liters]).

• If the inverted osmosis water filtration system pressure

is less than 21 PSI or 0,14 MPa (1,5 kg · f / cm ², more

than four (4) seconds to fill a 7 oz of capacity cup [0,2

liters]):

a) Identify if the sediments filter in the inverted osmosis

system is being blocked. Replace filter if necessary.

b) Allow inverted osmosis system storage tank to refill

after extensive usage.

c) Call a qualified plumber if the inverted osmosis water

pressure problem continues.

REQUIREMENTS

• 1/4” (6,35 mm) in diameter copper pipe

to connect refrigerator to the water
pipe. Make sure both terminals are
cut in a squared manner.

To determine how much pipe material is needed,

measures the distances between the valves located

behind the refrigerator and the source of water and add

to that 8 feet (2,4 m). Make sure there is sufficient pipe

material to allow the free movement of the refrigerator

from the wall

• A cold water source. Water pressure should be between

0,138 and 0,82 MPa or 20 and 120 PSI for models not

containing water filter and between 0,276 and 0,82

MPa or 40 and 120 PSI for models containing water

filter.

A drill.

Adjustable 1/2”(12,7 mm) key.

Flat and Phillips style (star) screwdriver.

• Two 1/4” (6,35 mm) diameter

compression nuts with two

sides to connect the copper

pipe to the refrigerator valve.

If your current copper pipe has some

reduction on the ends, it will be

necessary to get and adaptor (found

in hardware stores) to connect the

water line to the refrigerator. It is also

possible to cut such reductions with a pipe cutter and

use the compression connections mentioned above.

• Bypass valve to connect to

the cold water line. The valve

must have a water opening

with an interior 5/32” (3,46

mm) diameter in the cold-

water connection point.

These valves can be located

in any cold-water connection package. Before buying

make sure such valve meets local standards and

requirements.

INSTALLATION INSTRUCTIONS

Install the valve to the pipe that you use to drink water.

(Connect only to a potable water source).

CAUTION:

Connect to potable water supply only.

1. CLOSE THE MAIN WATER SOURCE

Open the nearest water faucet to let water flow and

empty pipes.

2. SELECT THE LOCATION OF THE

VALVE

Select the location of the valve that

will provide a better access. It is best

to connect to a vertical pipeline. When

connecting to a horizontal pipeline is

necessary, make the connection in the

lateral or upper area instead of the

lower area to prevent accumulation of

sediment.
