Special Rules for Outdoor Installa-
tions
Please observe the general setup, in-
stallation, and connection instructions.
Place the heat pump on a level and
solid surface with the necessary bearing
capacity. If not available, provide a
cement base, acc. to the snow height,
so that the feet of the outdoor unit
cannot be covered with snow. The heat
pump must be aligned with the ad-
justable feet.
Heater flow and return must be as short
as possible and well insulated to prevent
heat losses. The condensate drain must
be insulated and protected from frost
and have a siphon with a min. height of
100 mm routed into a closed drain.
The drain line must not have any cross-
section reductions and must be suffi-
ciently suitable to ensure problem-free
drainage.
The controller unit must be installed
inside of the building (temperature range
of +5°C to +40°C). The wall openings
for heater flow and return as well as the
electrical cables must be carried out
according to the rules and regulations.
Especially the flexible electrical cables
as well as the low voltage (230 or 400V)
and the extra-low voltage (sensor and
controller cable) must be shielded from
one another.
Selecting the Installation Site
Air intake and outlet must be kept
clean, unobstructed, and free of snow,
leaves, plants, machinery, etc. Comply
with min. clearances as specified for
air intake, outlet, misc. ducts, and
maintenance (see previous page).
Avoid an air short-circuit at all costs.
Use both sides for the air outlet if
strong winds, for example, may cause
an air short-circuit. The air intake must
be protected from aggressive or corro-
sive substances such as ammonia,
chlorinated substances, etc.
The AEROTOP T heat pump is very
quiet. However, since noise is per-
ceived differently by different people,
the heat pump should not be installed
near windows, sleeping or living
quarters (porch, edge of pool, etc.).
The distance to neighboring houses
should be sufficient as well. It is not
advised to install the heat pump in
recesses (possible echo or air short--
circuit). Local rules and regulations
apply.
Observe the checklist notes when
selecting the installation site for the
correct setup of an air-water heat
pump.
