5.6
Selecting the installation site
Danger!
Risk of injury due to ice formation.
The air temperature at the air outlet is below
the outdoor temperature. This can lead to ice
formation.
▶
Select a site and an orientation at which
the air outlet is at least 3 m away from
walkways, plastered surfaces and down-
pipes.
▶
Note that installation in sinks or areas that do not allow
free outflow of air is not permitted.
▶
If the installation site is in the immediate vicinity of the
coastline, ensure that the product is protected against
spraying water by an additional protection device.
▶
Keep away from flammable substances or flammable
gases.
▶
Keep away from heat sources.
▶
Do not expose the outdoor unit to dirty, dusty or corrosive
air.
▶
Keep away from ventilation openings or ventilation ducts.
▶
Keep away from deciduous trees and shrubs.
▶
Please note that the installation site must be below
2000 m above sea level.
▶
Please note the noise emissions. Maintain sufficient
clearance from noise-sensitive areas of the adjacent
building. Select an installation site that is as far away
from the windows of adjacent building as possible. Select
a location that is as far away from your own bedroom as
possible.
▶
Select an installation site that is easily accessible so that
maintenance and service work can be carried out.
▶
If the installation site is adjacent to a vehicle shunting
area, protect the product using ram protection.
Condition
: Especially for ground installation
▶
Avoid choosing an installation site that is in the corner of
a room, between walls or between fences.
▶
Prevent the return intake of air from the air outlet.
▶
Ensure that water cannot collect on the subsoil. Ensure
that the subsoil can absorb water well.
▶
Plan a bed of gravel and rubble for the condensate dis-
charge.
▶
Select an installation site which is free from significant
accumulations of snow in winter.
▶
Select an installation site at which the air inlet is not af-
fected by strong winds. Position the unit as crosswise to
the main direction of wind as possible.
▶
If the installation site is not protected against the wind,
you should plan to set up a protective wall.
▶
Please note the noise emissions. Avoid corners of rooms,
recesses or an installation site between walls. Select
an installation site with excellent sound absorption (e.g.
thanks to grass, hedges, fencing).
▶
Route the hydraulic lines and electrical wires under-
ground. Provide a safety pipe that leads from the outdoor
unit through the wall of the building.
