In case of a non quick coupling unit, make sure to have the professional after-sales service person or authorized dealer to install the units.

• The units may not be installed in places where there might be leakage of combustible gases: fire hazard.

• Make sure that an earth leakage circuit breaker is installed, either as a plug in device or on the main board, instead of a

fuse.

•Check whether the connection of wires between indoor and outdoor unit is not loose.

•Make sure that the air conditioner is properly grounded.
