General information
ensure that the surface on which
the heat pump is to be installed,
is horizontal, level, solid and
permanent. the entire heat pump
frame should be in contact with the
substrate. Uneven substrates can
increase the acoustic emissions of the
heat pump. the heat pump must be
accessible from all sides.
Special features
recommended substrate:
Cast concrete foundation
Kerb stones
stone slabs
Provide a recess (space) underneath
the heat pump to enable water and
electrical pipes/cables to be connected
from below.
Protection of heating water lines
against frost and moisture
Protect the flow and return lines in
external installations against frost by
means of adequate thermal insulation
and by routing them inside conduit
to protect them against moisture.
insulation thickness in accordance
with current regulations. the integral
frost stat (inside the heat pump) that
automatically starts the circulation
pump in the heat pump circuit at <+10
°C and thereby safeguards circulation
in all water-bearing components,
offers additional frost protection. Fill
the heating system with an antifreeze
mixture if the power supply cannot
be guaranteed for a longer period of
time.
Condensate drain
route the condensate drain hose with
a downward slope or to the side out
of the heat pump. when installing
the heat pump outside, route the
condensate to an existing drain or into
a coarse gravel soakaway. For this,
ensure an installation that is free from
the risk of frost.
