NB!: The overpressure device must be operated regularly,
at least every 30 days, to remove scale deposits and to
check that it is not blocked (fig. 14).
NB!: The discharge pipe connected to the overpressure
device must be installed in a continuous downward slope
and in a place protected against the formation of ice.
NB!: Connect a rubber hose to the condensate drain, tak-
ing care not to force too hard to avoid breaking the drain
hose.

5.5.1 Condensate drain connection
The condensate forming during heat pump operation flows
through a special drain pipe (½") that runs inside the insulation
casing and comes out the bottom of the equipment (fig. 13). It
must be connected to a duct so that the condensate can flow
regularly (see installation example fig. 16 and fig. 17).
