Electrical Safety

IMPORTANT

(PLEASE READ CAREFULLY)

FOR THE USER'S PERSONAL SAFETY, THIS

APPLIANCE MUST BE PROPERLY GROUNDED

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

(Fig. 15) to minimize the hazard of electric shock.

The customer should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded.

PREFERRED METHOD

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

(Fig. 16). The large slot in the adapter must be aligned with the large slot in the receptacle to assure a proper polarity connection.

CAUTION: 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 qualified 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.

Troubleshooting Tips

Save time and money! Review the chart below first and you may not need to call for service.

Normal Operation

• You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency.

• You may hear the thermostat click when the compressor cycles on and off.

• Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from the outdoor side of the unit.

• The fan may run even when the compressor does not.

Abnormal Operation

Problem

Air conditioner does not start

Air conditioner does not cool as it should

Air conditioner freezing up

Possible Causes

■

The air conditioner is unplugged.

■

The fuse is blown/circuit breaker is tripped.

■

Power failure.

■

■

The current interrupter device is tripped.

Airflow is restricted.

What To Do

• Make sure the air conditioner plug is pushed completely into the outlet.

• Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.

• When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload.

• Press the RESET button located on the power cord plug.

• If the RESET button will not stay engaged, discontinue use of the air conditioner and contact a qualified service technician.

• Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.

■

TEMP Control is set at too high a number.

■

The air filter is dirty.

■

■

The room may have been hot.

Cold air is escaping.

■

Cooling coils have iced up.

■

Ice blocks the air flow and stops the air conditioner from cooling the room.

• Clean the filter at least every 2 weeks.

See the operating instructions section.

• When the air conditioner is first turned on you need to allow time for the room to cool down.

• Check for open furnace floor registers and cold air returns.

• Set the air conditioner's vent to the closed position.

• See Air Conditioner Freezing Up below.

• Set the mode control at High Fan or High Cool with the high temperature.
