4. BEFORE OPERATION
CAUTION:
-
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 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.
