Before Operation

Preparing for Operation

1. Contact an installation specialist for installation.
2. Plug in the power plug properly.
3. Use a dedicated circuit.
4. Do not use an extension cord.
5. Do not start/stop operation by plugging/unplugging the power cord.
6. If the cord/plug is damaged, replace it with only an authorized replacement part.

Usage

1. 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.
2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items.

Cleaning and Maintenance

1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation, leading to possible electric shock.
3. 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.

Service

For repair and maintenance, contact your authorized service dealer.

How to Attach Drain Pan(Optional)

The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the air) is drained to the outside.

In very humid weather, (and for reverse cycle models in the reverse mode) excessive condensate water removed from the air may cause some water to collect. To remove this excess water you can install the drain

pan as detailed below.

1. Take the drain pan which is located in the air discharge.
2. Remove the hole rubber from the base-pan (for some models).
3. Install the drain pan to the right corner of the cabinet with 4 (or 2) screws.
4. Connect the drain hose of 3/5" inside diameter to the outlet located at the bottom of the drain pan. You can purchase the drain hose or tubing locally to satisfy your particular needs. (Drain hose is not supplied).

CABINET DRAIN PAN SCREW DRAIN HOSE

How to Connect a Drain Hose

A drain hole is provided at the rear of the air conditioner unit. Select a drain method according to the following.

1. Remove the hole rubber from the base-pan. (for some models)
2. Connect a drain hose of 916 " inside diameter to the drain pipe Fig. 1.
3. Or connect a pipe elbow of 916 " inside diameter to the drain pipe, then connect a drain hose of 916 " inside diameter to the pipe elbow as shown in Fig. 2.

Maintenance and Service

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

Air Filter Cleaning

The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles in the filter will build up and block the airflow. This reduces the cooling capacity and also causes an accumulation of frost on the cooling coils.

1 Open the inlet grille upward by pulling out the bottom of the inlet grille.(a)
In another case, you can open the inlet grille downward by pulling out the top of the inlet grille.(b)
2. Remove the air filter from the front grille assembly by pulling the air filter up or down slightly.
3. Wash the filter using lukewarm water below 40°C (104°F).(c)
4. Gently shake the excess water from the filter completely. Replace the filter.

Troubleshooting

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 Possible	Causes What To Do
Air conditioner does not start	■The air conditioner is unplugged.	·Make sure the air conditioner plug is pushed completely into the outlet.
	■The fuse is blown/circuit breaker is tripped.	·Check the house fuse/circuit breaker box and replace the fuse or reset the breaker.
	■Power failure.	·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.
Air conditioner does not cool as it should	■Airflow is restricted.	·Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
	■The THERMOSTAT may not be set high enough.	·Turn the knob to a higher number. The highest setting provides maximum cooling.
	■TEMP Control set to a higher number.	·Set the TEMP Control to a lower number.
	■The air filter is dirty.	·Clean the filter at least every 2 weeks. See the operating instructions section.
	■The room may have been hot.	·When the air conditioner is first turned on you need to allow time for the room to cool down.
	■Cold air is escaping.	·Check for open furnace floor registers and cold air returns.·Set the air conditioner's vent to the closed position.
	■Cooling coils have iced up.	·See Air Conditioner Freezing Up below.
Air conditioner freezing up	■Ice blocks the air flow and stops the air conditioner from cooling the room.	·Set the mode control at Med Fan or High Cool with the thermostat at 1 or 2.·Set the mode control at High Fan or High Cool with the high temperature.
