1.2. Before starting the trial run
Caution:
•
Before starting operation, check that all panels, guards and other
protective parts are correctly installed. Rotating, hot or high volt-
age parts can cause injuries.
•
Do not touch the refrigerant pipes with bare hands during opera-
tion. The refrigerant pipes are sometimes hot and sometimes cold
depending on the condition of the flowing refrigerant. Your hands
may suffer burns or frostbite if you touch the pipes.
•
Turn on the main power switch more than twelve hours before
starting operation. Starting operation just after turning the main
power switch on can result in severe damage to internal parts.
Keep the main power switch turned on during the operation sea-
son.
•
Keep the outlets and inlets free of obstacles. Otherwise, the per-
formance may be reduced or operation may stop.
1.2. Before starting the trial run
Caution:
•
Do not touch any switch with wet fingers, as this can cause an
electric shock.
•
Do not operate the air conditioner without the air filter set in place.
Dust may accumulate, and cause a failure.
•
After stopping operation, be sure to wait for five minutes before
turning off the main power switch. Otherwise, water leakage or
unit failure may occur.
