• DO NOT pull out the power cord when the power is ON.
This may cause serious electrical shocks which may result in fire hazards.
• Keep the indoor and outdoor units, power cable and transmission wiring, at least 3.5 ft from TVs and radios, to prevent distorted
pictures and static.
Depending on the type and source of the electrical waves, static may be heard even when more than 1m away.
CAUTION
• Do not install the air conditioner at any place where there is danger of flammable gas leakage.
In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out.
• While following the instructions in this installation manual, install drain piping to ensure proper drainage and
insulate piping to prevent condensation.
