2.3.3 Installation on a wall

NOTE
Either a light well or a rain guard should be used for the air outlet to avoid
shorting the air circuit.
2.4 Air-to-Water Heat Pumps for Outdoor Installation
Costs for outdoor installation
 Frost-free established foundation
 Laying insulating heating pipes for flow and return flow in the
ground
 Laying electrical connecting and main cables in the ground.
 Wall openings for connecting pipes
 Condensate outflow (frost-free)
Set-up
Heat pumps for outdoor installation are equipped with specially
coated steel and are thereby weatherproof.
The device should always be installed on a permanently even
and horizontal surface. Frost-free paving slabs or foundations
are suitable as a base. The entire frame should lie directly on the
ground to ensure a good soundproof seal and to prevent the
water-bearing components from becoming too cold. If there are
any gaps, these should be sealed with weatherproof insulating
material.

stones and 4 paving slabs
Minimum clearances
It must be possible to carry out maintenance work without
hindrance. This can be ensured by maintaining a clearance of
1.2 m to thick walls.
Sound insulation measures
The lowest noise emissions are achieved if, from the air outlet
side at a surrounding distance of 3-5 meters, there is no sound
reflection through sound-proof surfaces (i.e. facade).
Additionally, the foundation can be covered up to the height of
the covering panels with sound-absorbing material (i.e. bark
mulch).
Noise emissions from the heat pumps depend on the respective
sound power levels and the installation conditions. Please refer
to Chap. 5 on p. 144 for more detailed information about the
interrelationship between the factors influencing acoustic
emissions, sound propagation and acoustic immissions.
Shorting of the air circuit
When installing the heat pump, please keep in mind that the air
cooled by the extraction of heat is blown out freely. For
installation close to a wall, the air outlet cannot face in the wall's
direction.
Installation in a hollow or in an inner courtyard is not permitted
because cooled air collects at ground level and is drawn in again
by the heat pump during lengthy operation.
