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.
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.
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.
the condensate drain hose must be
routed 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.
