SAFETY INSTRUCTIONS

●If water enters the product, turn off the power at the main circuit, then unplug the product and call for service.

●If the product has been submerged, contact an LG Electronics Customer Information Center for instructions before resuming use.

●Unplug the product when unused for long periods.

●Unplug the product before cleaning.

●In the event of a gas leak (propane gas, etc.) do not operate this or any other appliance. Open a window or door to ventilate the area immediately.

●This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.

●The interior of the product must only be cleaned by an authorized service center or a dealer.

●Do not use solvent-based detergent on the product. Doing so can cause corrosion or damage,

product failure, electrical shock, or re.

GROUNDING INSTRUCTIONS

●The power cord of this appliance is equipped with a three-prong (grounding) plug. Use this with a standard three-slot (grounding) wall power outlet to minimize the hazard of electric shock. The

customer should have the wall receptacle and circuit checked by a qualied electrician to make

sure the receptacle is properly grounded. DO NOT CUT OR REMOVE THE THIRD (GROUND) PRONG FROM THE POWER PLUG.

- Situations when the appliance will be disconnected occasionally; Because of potential safety hazards, we strongly discourage the use of an adapter plug. However, if you wish to use an adapter, a TEMPORARY CONNECTION may be made. Use UL-listed adapter, available from most local hardware stores. The large slot in the adapter must be aligned with the large slot in the receptacle to assure a proper polarity connection.

●Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal, and not insulated, and the wall receptacle is grounded

through the house wiring. The customer should have the circuit checked by a qualied electrician

to make sure the receptacle is properly grounded.

●Disconnect the power cord from the adapter, using one hand on each. Otherwise, the adapter ground terminal might break. Do not use the appliance with a broken adapter plug.

- Situations when the appliance will be disconnected often; Do not use an adapter plug in these situations. Unplugging the power cord frequently can lead to an eventual breakage of the ground terminal. The wall power outlet should be replaced by a three-slot (grounding) outlet instead.

How to Install the Unit

To prevent vibration and noise, make sure

the unit is installed securely and firmly. Install the unit where the sunlight dose not

shine directly on the unit. The outside of the cabinet must extend out-

ward for at least 12" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will

prevent heat radiation of the condenser. Restriction of outside air will greatly reduce

the cooling efficiency of the air conditioner.

Awning

Cooled air

radiation

CAUTION

● All side louvers of the cabinet must remain exposed to the outside of the structure.

Install the unit slightly tilted so the back is

slightly lower than the front (about 1/2"). This will force condensed water to flow to the outside.

Install the unit with the bottom between

30" ~60" above the floor level.

Fence

Clearance

Proper clearance enhances the cooling efficiency of the product.

If a storm window presents interference,

fasten a 2” wide wood strip to the inner window sill across the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame.

(See drawing.) The top of the wood strip on

the inside sill should be approximately ¾” higher than the storm window frame or wood strip on the outside sill to help condensation to drain properly to the outside.

If necessary, install a second wood strip

(same thickness as first strip) across the full width of the outer sill, flush against the back of the inner sill.
