When moving your appliance away from the wall, be careful not to roll over the power
cord or to damage it in any way. Do not crush or damage the water line.
After your refrigerator is in operation, do not touch the cold surfaces in the freezer
compartment, particularly when your hands are damp or wet. Skin could adhere to
these extremely cold surfaces.
Unplug the power cord from the power outlet for cleaning or other requirements. Never
touch it with wet hands because you can get an electric shock or be injured.
Never damage, bend, kink, pull out, or twist the power cord because damage to the
power cord can cause product failure, fire, or electric shock. If you have doubts the
appliance is properly grounded, consult a qualified electrician.
Never place glass products in the freezer because they may be broken from expansion
when their contents are frozen.
Never put your hands within the ice storage bin of the automatic icemaker. You can be
injured by the operation of the automatic icemaker.
The appliance is not intended for use by young children without supervision.
Young children should be supervised to ensure that they do not play with the appliance.
Never allow anyone to climb, sit, stand, or hang on the door. These actions may
damage the refrigerator and even tip it over, causing severe personal injury.
Before you move your refrigerator into its final location, it is
important to make sure you have the proper electrical connection.

DANGER: Risk of child entrapment.
Before you throw away your old refrigerator or freezer take off the doors but leave the
shelves in place so that children may not easily climb inside.
The appliance is not intended for use by young children without supervision.
Young children should be supervised to ensure that they do not play with the appliance.
Don’t store or use gasoline or other flammable vapor and liquids in the vicinity of this or
any other appliance.
In the event of an electric short circuit, grounding (earthing) reduces the risk of electric
shock by providing an escape wire for the electric current.
In order to prevent possible electric shock, this appliance must be grounded.
Improper use of the grounding plug can result in an electric shock. Consult a qualified
electrician or service person if the grounding instructions are not completely
understood, or if you have doubts on whether the appliance is properly grounded.

Please keep the refrigerator at a proper
distance from other things. Too small a
distance from adjacent items may result in
lowered freezing capability and increased
electricity charges consumption.
Select a place where a water supply can be
easily connected between the automatic ice
maker and dispenser.
Installing the refrigerator in a wet or damp
area may cause rust and may be an electrical
hazard.
If this refrigerator is installed where the
ambient temperature is high, the freezing
capacity is deteriorated and the cost of
electricity used increases.
Where to install
Unstable installation may cause vibration and
noise. If the floor to install the refrigerator on
is not even, make the refrigerator level by
rotating the height adjusting screw.
•
Install the refrigerator at a place where the ambient temperature is 5˚C ~ 43˚C
(41˚F~110˚F).

Water supply installation
Pass the refrigerator laterally through the access
door as shown in the right figure.
Automatic icemaker operation needs water pressure of 21~121 psi (1.5~8.5
kgf/cm2) (That is, an instant paper cup (6 oz. or 180 cc) will be fully filled within
3 seconds.)
If water pressure is less than 21 psi (1.5 kgf/cm2). It is necessary to purchase a
separate pressure pump for normal automatic icemaking and cool water feed.
Keep the total length of the feed water pipe tube within 26’ (8 m). Be careful for the
tube to avoid being kinked. If the tube is longer than 26’ (8 m), the pressure may
drop to an unacceptable level.
Install the water supply line where it will not be affected by heat.
Connect to potable water supply only.
Mount them in the reverse sequence of removal after they pass through the access
door.
Pass the

•
All installations must be in accordance with local plumbing code requirements.
•
Use copper tubing and check for leaks.
•
Install copper tubing only in areas where temperatures will remain above freezing.
•
It may take up to 24 hours for your icemaker to begin producing ice.
IMPORTANT
The icemaker water valve contains a flow washer which is used as a water
pressure regulator.

•
Your refrigerator dealer has a kit available with a 1/4-inch saddle-type shut-off valve,
a union, and copper tubing. Before purchasing, make sure a saddle-type valve
complies with your local plumbing codes. Do not use a piercing-type or 3/16-inch
saddle valve which reduces water flow and clogs more easily.

1. Unplug the refrigerator or disconnect power.
2. Turn OFF the main water supply. Turn on the nearest faucet to relieve the
pressure on the line. It may help to open an outside faucet to allow the water to
drain from the line in the house.
3. Find a

Connect
the tubing to

•
Horizontal pipe will work, but the following precaution must be taken: Drill on the top of
the pipe, not the bottom. This will help keep water away from the drill. This also keeps
normal sediment from collecting in the valve.
NOTE
4. To determine the length of copper tubing you will need, measure from the
connection on the lower left rear of the refrigerator to the water pipe. Add 7
feet (2.1m) to allow for moving refrigerator for cleaning. Use

(outside diameter) copper tubing. Be sure both ends of copper tubing are cut
square.
5. Using a drill, drill a
1
/

-inch hole in the cold water pipe you have selected.
6. Fasten shut-off valve to cold water pipe with pipe clamp. Be sure the outlet
end is solidly in the
1
/

" drilled hole in the water pipe and the washer is under
the pipe clamp. Tighten the packing nut. Tighten the pipe clamp screws
carefully and evenly so the washer makes a watertight seal. Do not
overtighten or you may crush the copper tubing, especially if soft (coiled)
copper tubing is used. Now you are ready to connect the copper tubing.
7. Slip the compression sleeve and the compression nut onto the copper tubing
as shown. Insert the end of the tubing into the outlet end squarely as far as it
will go. Tighten the compression nut onto the outlet end with a wrench. A flare
nut wrench works best, but an open end wrench will suffice. Do not
overtighten.
8. Place the free end of the tubing into a container or sink, and turn on the main
water supply. Flush out the tubing until the water is clear. Turn off the shutoff
valve on the water pipe. Coil the copper tubing as shown below.

Before making the connection to the refrigerator, be sure the refrigerator
power cord is not plugged into the wall outlet.
• If your refrigerator does not have a water filter, we recommend installing
one. If your water supply has sand or particles, that could clog the screen of
the refrigerator’s water valve. Install the filter in the water line near the
refrigerator.
1. Remove the plastic flexible cap from the water valve.
2. Place the compression nut and ferrule (sleeve) onto the end of the tubing as
shown.
3. Insert the end of the copper tubing into the connection as far as possible. While
holding the tubing, tighten the fitting.
Connect the tubing to
the refrigerator
Tighten any connections that leak.
