ATTENTION
Use original packing to ship the air conditioner to any other destination.
If packing disposal is necessary, we remind to dispose different materials suitably.
6. Installation
Installation and intervention on air conditioners might imply risks, as they are pressurized systems
in the presence of electric components. Thus, installation and maintenance are reserved only to
personnel skilled and qualified in the installation and maintenance of cooling plants
6.1. Positioning the unit
WDE units must be installed on the
external wall of the shelter / room to be
conditioned. Check that there is enough
room for easy application, installation
and servicing, both inside and outside
the shelter. Always observe the minimum
spaces indicated in the following drawing.

DANGER
Do not obstruct circulation of air being sucked into or expelled from the air conditioner.
Avoid short circuits of air on both the internal (evaporator) side and the external (condenser) side.
Short circuits on the evaporator side cause:
• The reduction of the unit efficiency;
• A bad distribution of air inside the shelter;
• At worst, the intervention of anti-freeze protection which stops compressor.
It is important also to prevent hot air expelled by the condenser fan from being even partially sucked
back in. This would cause continuous stoppages, commanded by the pressure switches, with:
