Safety
Precautions
Prior to Operation
Preparing for operation
1 Contact an installation specialist for installation.
2 Plug in the power plug properly.
3 Do not use a damaged or non-standard power cord.
4 Do not share the same outlet with other appliances
5 Do not use an extension cord.
6 Do not start/stop operation by plugging/unplugging the power cord.
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). Usage in such a manner could harm such property.
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.

■ THERMOSTAT
The THERMOSTAT is used to maintain the room temperature. The compressor will cycle on and off to keep
the room at the same level of comfort. When you turn the knob to a higher number(the right side) and the
indoor air will become cooler.
The 5 or 6 position (the middle position of arc) is a normal setting for average conditions.
■ AUTO SWING
Auto swing switch controls the horizontal air direction by air swing system (not on all models).
ON (

) : Auto swing is not operated.
■ TIMER
The timer can control the operation times within 12 hours. If you set the timer switch at the "1" position, after
1 hour the unit will be stopped automatically. If you want to operate continuously, set the timer switch at the
"CONSTANT" position. The timer switch cannot rotate further colckwise from the "CONSTANT" position. If
you set the timer switch at the "STOP" postion, the unit will be stopped all operations.
CAUTION: When the air conditioner has been performed its cooling operation and is turned off or
set to the fan position, wait at least 3 minutes before resetting to the cooling operation again.

FAN
Turn the thermostat control to the desired
setting. The control position is a normal setting for
average conditions. You can change this setting, if
necessary, in accordance with your temperature
preference.
The thermostat automatically controls cooling or

Common
Issues
Common Problems and Solutions
Before calling for service, please review the following list of common problems and solutions.
The air conditioner is operating normally when:
• You hear a pinging noise. This is caused by water being picked up by the condenser on rainy days or in highly
humid conditions. This feature is designed to help remove moisture in the air and improve cooling efficiency.
• You hear the thermostat click. This is caused by the compressor cycle starting and stopping.
• You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid
conditions or on rainy days. This water overflows and drips from the rear of the unit.
• You hear the fan running while the compressor is silent. This is a normal operational feature.
The air conditioner may be operating abnormally when:
