6. Exterior installation
6.1. 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
immediate site profi le.
Space requirements:
The heat pump must be positioned so that there is
suffi cient space for air intake and air outlet (see mini-
mum 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.
Condensation pipe:
The condensation pipe must be laid so that the
water can also fl ow off even at outside temperatures
below 0°C. A heatable siphon should be fi tted.
Alternatively, an electrical self-regulating heating
cable can be used that is selected via the Navigator
Control.
Frost protection:
If, in the case of bivalent-alternative operation, the
HP is shut down at low outside temperatures, there
is a potential danger that the heating lines and the
condenser plate heat exchanger could freeze.
The following frost protection options are possible:
- Electrical self-regulating heating cable on pipes and
condenser
- Frost protection function of the control system.
Heating connections:
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.
It might be necessary to install a self-regulating elec-
trical heating cable to protect the lines from frost.
Installation location:
Despite the reduction in speed during the night, the
heat pump should not be positioned adjacent to a
living room or bedroom. The relevant installation
guidelines conforming to EN 378, for example, must
be observed.
