Air purging heat emitters or collectors
We recommend to purge air with the unit's air purge function (see

Before you
purge air from heat emitters or collectors, check if
or
is displayed on the home screen of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to
purge air is sufficiently ventilated.
Reason:
Refrigerant
might leak into the water circuit, and subsequently into
the room when you purge air from the heat emitters or
collectors.
