Do not change the high-pressure switch locally or change
the high pressure cut-out set value locally. If changed, it will
cause serious injury or death due to explosion.
Do not attempt to turn service valve rod beyond its stop.
6 BEFORE OPERATION
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.
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.
7 REMOTE CONTROLLER

please refer to its corresponding Installation and Operation Manuals.
