wiring connection without referring to our installation manual. If the instructions are not followed, it
may result in a water leakage, electric shock or a fire.
•
Do not pour water into the indoor unit or outdoor unit. This product contains electrical components
and if wet, can cause serious electrical shock.
•
Do not open the service cover or access panel for the indoor or outdoor unit without turning OFF the
main power supply.

extinguish any naked flames and contact your service contractor, if refrigerant leakage occurs.
•
The installer and system specialist shall ensure safety against refrigerant leakage according to local
regulations or standards.
•
Use the ELB which is above medium reaction speed (residual-current circuit breaker, action time of 0.1s
