DRAINING THE WATER HEATER (IF DOCKED)
The siphon principle is used to empty the hot water
heater. This can be done either via the drain valve on
the incoming cold water pipe or by inserting a hose into
the cold water connection.
DRAINING THE CLIMATE SYSTEM
In order to carry out service on the climate system, it
may be easier to drain the system first. This can be done
in different ways depending on what needs doing:
NOTE
There may be some hot water when draining
the heating medium side/climate system. There
is a risk of scalding.
