3

Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.

Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Usage in such a manner could harm such property.

Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.

Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.

When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit.

Maintenance

Care and Maintenance

TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.

• TO CLEAN FILTER

The Air Filter will become dirty as it removes dust from the inside air.

Do not force

It should be washed at least every 2 weeks.

If the Air Filter remains full of dust, the air flow will decrease and the cooling capacity will be reduced, possibly damaging the unit.

1. Pull the inlet grille forward and pull out the air filter. (Fig. 1)

2. Wash the Air Filter in warm 104°F(40°C) water. (Fig. 2)

Be sure to shake off all the water before replacing the filter.

• CLEANING THE AIR CONDITIONER

The front grille and Inlet grille may be wiped with a cloth dampened in a mild detergent solution. (Fig. 3)

The cabinet may be washed with mild soap or detergent and lukewarm water, then polished with

Liquid Wax for Appliances.

To ensure continued peak efficiency, the condenser coils(outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from the atmosphere.

• HOW TO SECURE THE DRAIN PIPE

In humid weather, excess water may cause the BASE

PAN to overflow. To drain the water, remove the

DRAIN CAP and secure the DRAIN PIPE to the rear hole of the BASE PAN Fig.4.

Installation Instructions

Read completely, then follow step by step.

• The appliance shall be installed in accordance with national wiring regulation.

• If a power plug isn't to be used, provide a circuit breaker between power source and the unit, as following picture.

To prevent vibration and noise, make sure the unit is installed securely and firmly.

Install the unit where the sunlight does not shine directly on the unit.

D

There should be no obstacle, such as a fence or wall, within 50cm 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.

Install the unit a little obliquely outward not to leak the condensed water into the room (about 5 ~ 10mm or 1/4 bubble with level).

CAUTION:

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

Troubleshooting Tips

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

Normal Operating

• 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.

■

■

■

■

■

Airflow is restricted.

The THERMOSTAT may not be set high enough.

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.

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.

• If power failure occurs, turn the mode control to

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

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

• Turn the knob to a higher number. The highest setting provides maximum cooling.

• Clean the filter at least every 2 weeks.

See the care and maintenance 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 the High Fan ( ) or
