INSTALLATION GUIDE

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.
