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. 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.

A 115 Volt, 60 Hz., AC only, 15 or 20 amp, fused and grounded single-outlet circuit is required. Use an outlet that cannot be turned off by a switch. Do not use an extension cord.

The refrigerator-freezer should be so positioned that the supply plug is accessible for quick disconnection in the event of an emergency.

If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid any hazard.

Do not modify or extend the Power Cord length.

Warning

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

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.

Warning

•

If operating the refrigerator before installing the water connection, turn the 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.

IMPORTANT

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 21 psi (lb/inch2)

Tools required

•

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.

NOTE

Installation

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

-inch vertical COLD water pipe near the refrigerator.

Connect

the tubing to

water line

•

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

-inch O.D.

(outside diameter) copper tubing. Be sure both ends of copper tubing are cut square.

5. Using a drill, drill a

-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

" 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.

Installation

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.



Plug In the Refrigerator

Arrange the coil of copper tubing behind the refrigerator so it does not vibrate against the back of the refrigerator or against the wall. Push the refrigerator back to the wall.
