4. Placement and Installation
4.1. Installation instructions
The TERRA AL Twin is only designed for exterior
installation. Special actions has to be set for frost
protections.
Despite the possibility of speed reduction, the heat
pump should not be positioned adjacent to a living
room or bedroom. The relevant installation guide-
lines conforming to EN 378, for example, must be
observed.
4.2. Customer preparation
Foundation:
The foundation should be level and stable. A base
can be provided by the customer or a paving slab can
be laid on a gravel base. The air source heat pump
should be positioned slightly higher than the immedi-
ate site pro
fi
le.
Space requirements:
The heat pump must be positioned so that there
is suf
fi
cient space for air intake and air outlet (see
minimum distances for exterior installation). It should
not be possible for the inlet and exhaust air openings
to become blocked by snow, leaves, etc. Installation
in wall niches is to be avoided.
Inlet air:
The inlet air must be free of impurities such as sand
and caustic materials such as ammonia, sulphur,
chlorine, etc.
4.3. Condensation run-off
Air source heat pumps generate condensed water
when in operation. Per defrosting cycle, i.e. within 2
minutes up to 15 lt. of condensate can accumulate.
The condensation outlet should be conveyed into the
waste water channel by using the appropriate pipe
diameter for the machine.
The condensate must be able to run of also at tem-
peratures below 0 °C. The easiest way to guarantee
is by using the mounted heating cable, aktivated by
the Navigator control.
4.4. Heating connections
The heating connections must be installed with the
fl
exible hoses which are included to the heat pump
as a standard.
In general, all lines outdoors should be kept as short
as possible. All pipes and wall openings must be pro-
fessionally heat-insulated and frost-protected during
installation.
4.5. Air outlet
On the air outlet exists an increased risk of frost. Rain
pipes, water-carrying pipes or water-carrying contai-
ners must not be located next to the outlet side.
