Important safety instructions

Before use, this refrigerator must be properly installed and located in accordance with the installation instructions in this manual.

Never unplug your refrigerator by pulling on the power cord. Always grip the plug firmly and pull it straight out from the outlet.

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.

Child entrapment	DANGER: Risk of child entrapment.
warning	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 Don’t store or use gasoline or other flammable vapor and liquids in the vicinity of this or any other appliance.

Grounding	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.

Where it is free If this refrigerator is installed where the from heat ambient temperature is high, the freezing

capacity is deteriorated and the cost of electricity used increases.

NOTE

•Install the refrigerator at a place where the ambient temperature is 5˚C ~ 43˚C (41˚F~110˚F).

Ambient temperature outside this range may cause product malfunction. Also, the tube between the dispenser and automatic ice maker may freeze.

Water supply installation

Before Automatic icemaker operation needs water pressure of 21~121 psi (1.5~8.5 installation kgf/cm2) (That is, an instant paper cup (6 oz. or 180 cc) will be fully filled within

3 seconds.)

If water pressure does not reach the rating 21 psi (1.5 kgf/cm2) or below, it is necessary to purchase a separate pressure pump for normal automatic icing 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 26’ (8 m) or longer it may cause trouble in water feed owing to the drain water pressure.

Install the water supply line where it will not be affected by heat.

Warning Connect to potable water supply only.

Disposal of the This appliance contains fluids (refrigerant and lubricant) and is made of parts and old appliance materials which are reusable and/or recyclable.

All the important materials should be sent to the collection center of waste material and can be reused after rework (recycling). For recycling, please contact the local agency.

Water connection instruction guide

Connecting Read all directions carefully before you begin. the refrigerator

to a water source

Warning Connect to potable water supply only.

IMPORTANT

•If operating the refrigerator before installing the water connection, turn icemaker to the OFF position to prevent operation without water.

•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.

Tools required Standard screwdriver

7/16-inch and 1/2-inch open-end wrenches or two adjustable wrenches

1/4-inch nut driver

1/4-inch drill bit

Hand drill or electric drill (properly grounded)

NOTE

•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.

Cold water supply The icemaker water valve contains a flow washer which is used as a water pressure regulator.

The icemaker needs to be connected to a cold water line with water pressure 20 ~ 120 psi (lb/inch2)

		the line in the house.
		3. Find a 1/2-inch vertical COLD water pipe near the refrigerator.
		NOTE
		• 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.
		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 1/4-inch O.D.
		(outside diameter) copper tubing. Be sure both ends of copper tubing are cut
		square.
		5. Using a drill, drill a 1/4-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 1/4" 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. Screw 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.

•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.
