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 (up to 50°C). If the water
temperature is higher than 50 °C, it will cause damage to plastic parts.
