4. BEFORE OPERATION
!
CAUTION
• Supply electrical power to the system for approximately 12 hours
before start-up or a long shut-off. 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 shut-off 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 than 50 °C, it will cause damage
to plastic parts.
