Foundations
Site the heat pump horizontally on a per-
manently solid surface. We recommend
laying concrete foundations as shown in
the following diagrams.
■ Provide an adequately sized
recess (see diagram below) in the
foundations to permit the lines (heat-
ing water flow and return, cables and
condensate drain) to be brought into
the heat pump from below.
■ Design the foundations, supporting
surface and cable ducts so that small
animals cannot get into the heat pump
or cable ducts.
■ Drain all condensate derived from the
air (subject to temperature and relative
humidity up to 20 l/h) via a DN 40 drain
pipe, which should be protected from
frost and provide a steady fall.
If possible connect the condensate
drain to a drainage or sewer system.
In this case, provide a siphon with a
backup level of at least 60 mm in the
frost-protected area.
Where the ground is able to absorb
water, the condensate can be soaked
away down to a frost-free depth into a
gravel bed.
■ Where appropriate, provide thermal
insulation or a ribbon heater around
the condensate drain hose on site.
