Each time the machine is turned on after being idle for a long
period, ensure there is no air in the heat exchanger.
Before using the unit for air conditioning, check that:
! condensate drainage is performed correctly:
! the heat exchanger fins are not obstructed by deposits of dirt.
If necessary clean the fins with low pressure compressed air
or steam without damaging the fins.
