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.

Preferred method  
Ensure proper ground  
exists before use  
WARNING: Do not cut or remove the grounding prong from the  
power plug.  
WARNING: 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

Electrical Safety  
Temporary Use of an Adapter  
We strongly discourage the use of an adapter due to potential safety hazards. For temporary  
connections, use only a UL-listed adapter, available from most local hardware stores. Ensure that the  
large slot in the adapter is aligned with the large slot in the receptacle for a proper polarity connection.  
To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground  
terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal  
damage.  
Temporary method  
Adapter Plug  
Metal Screw  
Receptacle Cover  
WARNING: Never use the appliance with a broken adapter.  
Temporary Use of an Extension Cord  
We strongly discourage the use of an extension cord due to potential safety hazards. For temporary  
situations, use only CSA certified and UL listed 3-wire grounded extension cords, rated 15 A, 125 V.

Common Problems and Solutions  
Before calling for service  
If you have problems with your air conditioner, read the following information and try to solve  
the problem. If you cannot find a solution, turn off the air conditioner and contact your dealer.  
Air conditioner does not operate  
1. Ensure that the air conditioner is plugged into a proper outlet.  
2. Check the fuse or circuit breaker.  
3. Check whether the voltage is unusually high or low.  
Air does not feel cold enough on the cooling setting  
1. Ensure that the temperature settings are correct.  
2. Check to see if the air filter is clogged with dust. If so, replace the filter.  
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 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.
