NOTE:
- If the LOW fan speed is selected and the outdoor
temperature is higher than 21°C, the compressor is
subjected to an excessive load when operating in heating
mode.
Therefore, the fan speed should be set to HIGH or
MEDIUM to avoid activating the safety devices.
- When the system is restarted after a shutdown of more
than approximately 3 months, the system should be
checked by your service provider.
- Turn off the main switch when the system is to be
inoperative for a long period of time. Otherwise the system
consumes electricity as the oil heater remains active even
though the compressor is stopped.
