C A U T I O N
Supply electrical power to the system for approximately 12 hours be-
fore start-up or a long shutdown. Do not start the system immediately
after power supply, it may cause a compressor failure because the
compressor is not heated well.
When the system is started after a shutdown longer that approxi-
mately 3 months, it is recommended to check the system by your
service contractor.
7 REMOTE CONTROLLER
It is advisable to use PC-ART or PC-ARF remote controller (both optional). For more information about it installation and operation,

Turn OFF the main switch when the system is to be stopped for a
long period of time: If the main switch is not turned OFF, electric-
ity will be used, because the oil heater is always energised during
compressor stopping.
Make sure that the outdoor unit is not covered with snow or ice.
If covered, remove it by using hot water (approximately 50°C). If
the water temperature is higher that 50 °C, it will cause damage
to plastic parts.
