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.
