• Supply electrical power to the system for approximately 12 hours
before 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 approximately
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, electricity will be
used, because the oil heater is always energised during compressor
stopping.
• Make sure that the RASC 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.
