the start of the manual air purge of the main zone or
additional zone.
Air purging heat emitters or collectors
We recommend to purge air with the unit's air purge function (see
above). However, if you purge air from the heat emitters or
collectors, mind the following:
WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if
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.
