Foundations
Site the heat pump horizontally on a permanently 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 (heating
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 drain-
age or sewer system. In this case, provide a siphon
with a backup level of at least 60 mm in the frost-pro-
tected area.
Where the ground is able to absorb water, the con-
densate 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.
