To avoid vibration or water leakage.
Do not install the unit where combustible gas may leak.
If the gas leaks and accumulates around the unit, an explosion may result.
Use power cables of sufficient current carrying capacity and rating.
Cables that are too small may leak, generate heat, and cause a fire.
Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a
consumer air conditioner, not a precision refrigeration system.

capacity.
When installing the unit in a hospital, communication station, or similar place, provide sufficient
protection against noise.
The inverter equipment, private power generator, high-frequency medical equipment, or radio
communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On

Oil, steam, sulfuric smoke, etc. can significantly reduce the performance of the air conditioner or damage
its parts.
