 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.
