The end of the heating or cooling season is the right time for cleaning and checking the system.
Cleaning
Filters, external heat exchanger, and drains are cleaned.
Hydraulic circuit
A closed circuit should not be emptied arbitrarily unless there is a reason, because refilling it introduces new oxygen.
Power supply
Complete power disconnection for long periods should only be done according to the manufacturer's instructions, especially when there is a crankcase heater or anti-freeze logic.
