DRAINING THE CLIMATE SYSTEM
In order to carry out service on the climate system, it
may be easier to drain the system first using the filler
valve (QM11).
NOTE
There may be some hot water when draining
the heating medium side/climate system. There
is a risk of scalding.
1.
Connect a hose to the lower filler valve for heating
medium (QM11).
2.
Open the valve to drain the climate system.
