8.1 Siting instructions
When selecting the installation site, observe the following points:
- The heat pump must be accessible on all sides The intake area should preferably be on a wall.
- The air discharge side must be free from obstruction. Since the air being discharged is around 8 K
colder than the ambient temperature, premature ice formation should be expected. Therefore do
not discharge the air directly onto walls, patios or footpaths. There should be at least 3 m clearance
between the heat pump discharge and walls, patios, footpaths, etc.
- To prevent air short circuits and sound reflection, avoid installation in recesses or between two walls.
- Installation in a depression is not permitted as the cold air will sink and no air exchange will take place.
- To avoid causing disturbance, bear in mind the sound levels and distance from neighbouring
properties when selecting a site.
- Do not position the heat pump directly in the prevailing wind direction / avoid air short circuits
- The condensate should drain away into the gravel bed.
- Protect air intake/discharge from leaves and snow.
- Provide thermal insulation for underground pipes.
Do not site the air source heat pump for outdoor installation in an environment that is polluted with
corrosive gases, such as acids or alkaline gases.
Do not install in a location directly exposed to onshore winds, as this will result in a risk of corrosion
from the saline air, particularly on the evaporator fins. In locations with strong winds it may be
necessary to construct wind protection to divert the onshore wind.
Strong winds may interfere with evaporator ventilation.
When the outdoor module is installed on flat roofs there may occur considerable wind loads, depen-
ding on bulding height and wind load zone. We recommend to get the substructure planned by a
specialist consultant or a structural engineer, taking into account the carrying capacity of the roof and
the wind loads, in accordance with the specific standards and regulations of each country.
In areas with high snowfall or in very cold places, protective measures must be taken to ensure that
the heat pump operates correctly.
If necessary, incorporate the system into the lightning and overvoltage protection systems.
Do not install the heat pump with the discharge side facing the prevailing wind direction.
Refrigerant lines, insulating materials, connecting cables, installation ducts or tubes, etc.,
must be weatherproof, UV-resistant and protected from mechanical damage.
