• Turn on the electrical power supply to the system approximately 12 hours before start-up after a long shutdown. Do not start the sys-
tem immediately after connecting the power supply, because the compressor may be damaged if it is not sufficiently heated.
• Make sure the outdoor unit is not covered with ice or snow. If it is, remove the ice or snow with warm water (no hotter than 50°C). If
the water temperature is over 50°C, the plastic parts may be damaged.
• When the system is started after being out of use for more than 3 months, we recommend that the system is checked by the service
provider.
• If the system is not going to be used for a long period of time, turn it off at the mains. Otherwise it will continue to consume electricity,
since the oil heater remains on even when the compressor is off.
