Installation Site Requirements - Viessmann Vitocal 300-A Series Installation And Service Instructions For Contractors

Siting and transport requirements
!
Please note
Impacts, compression and tensile loads can
cause damage to the outside panels of the
appliance.
Never put weight on the top, front or side panels
of the appliance.

Installation site requirements

The heat pump may only be sited outside the build-
ing on solid foundations: See page 10.
■ Provide a manual drain for the heating water flow
and return lines in any area at risk from frost.
Drain the system if the heat pump is shut down or
there is a prolonged power failure.
If the heat pump control unit, secondary pump and
■
heating circuit pumps are ready for operation, the
frost protection function of the heat pump control unit
is enabled.
On heat pump systems where a power failure cannot
be recognised, e.g. a holiday home, operate the
heating circuit with a suitable antifreeze or drain it.
To prevent an increase in noise level due to reflec-
■
tion, avoid siting equipment in recesses, at building
corners or between 2 walls.
■ Site the heat pump so that it is protected against
strong winds.
Note
In heavy snowfall, the air discharge grilles in the
lower area of the heat pump must be kept free of
snow and ice.
Requirements for the heat pump controller installation location
The heat pump control unit may only be installed
inside the building on a wall: See page 22.

Please note
Unfavourable ambient conditions can lead to
malfunctions and appliance damage.
■ The installation room must be dry and free
from the risk of frost.
■ Ensure ambient temperatures between 0 and
35 °C.

Please note
Tilting the compressor at a steep angle inside
the heat pump can result in appliance damage.
Max. tilting angle: 45° for a very short time
Lawn areas and vegetation can reduce noise devel-
■
opment. Only the heat pump foundations should
therefore be made from reverberant material (con-
crete).
■ Provide drainage or sewer pipes for draining the con-
densate.
Never install the heat pump next to living rooms or
■
bedrooms.
■ The air in the discharge area is approx. 10 K colder
than the ambient air. Therefore, black ice could
develop in the discharge area even at [ambient] tem-
peratures above freezing. Observe a clearance of
3 m to pavements or terraces.

Danger
Dust, gases and vapours can be damaging to
health and trigger explosions.
Avoid dust, gases and vapours in the installation
room.
