The air flow through the evaporator must not be
obstructed by surrounding buildings. A reduced air
flow rate can lead to loss of efficiency in the system.
Please note the following with regard to installation in
coastal areas:
►
The standard design of outdoor unit must be installed
at least 1 km from the sea.
►
Outdoor units with special coating, suitable for coast-
al locations, must be installed at least 200 m from the
sea.
►
The installation location selected should always be on
the leeward side of the building (the side facing away
from the sea).
Please note the following with regard to sound emissions
from the outdoor unit:
►
Avoid installing on reverberant flooring.
►
Avoid installing between building walls. The walls can
increase the noise level.
►
Avoid installing next to bedrooms.

»
Use underground waste pipes (with a smooth inner
surface) for the pipe liner.
