Prior to Operation
Prior to 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 a long time may be hazardous to your health. Do not expose
occupants, pets, or plants to direct airflow for a long time.
2. Due to the possibility of oxygen deficiency, ventilate the room when using the appliance together with
stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purpose (e.g. preserving precision devices,
food, pets, plants, or art objects). Such use may damage your properties.
Cleaning and Maintenance
1. Do not touch the metal parts of the unit when removing the filter. Injury can occur.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,
leading to 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 triggered while
cleaning inner parts of the unit.

3. Ensure that the air flow from the outside is not obstructed and that there is a clearance of
over 20" between the back of the air conditioner and the wall or fence behind it.
4. Close all doors and windows and check for any source of heat in the room.
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 fan on rainy days
or in highly humid conditions. This feature is designed to help remove moisture in the air
and improve cooling efficiency.
• 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.
