Moreover, it is important to ensure an adequate
ventilation of the premises where the equipment is to be
installed.
An alternative solution is indicated in the following
illustration (Fig. 4 and 4b): this consists of a second
duct that draws air in from outside instead of directly
from inside the premises.

Carry out the installation of each air duct taking care
that:
The weight of such does not adversely affect the
equipment itself;
Maintenance operations can be carried out;
This is adequately protected so as to avoid the
accidental intrusion of material inside the
equipment itself;
It doesn't exceed the maximum suggested length
of 6 meters (with 2 elbow junctions 90°).
The maximum total allowable pressure drop for all
components, including through holes for mounting
on external wall, within the pipe system does not
exceed 120 Pa.
During operation, the heat pump tends to lower
the ambient temperature if the external air duct
is not carried out.
An appropriate protection grid must be installed
in line with the discharge pipe conveying air to
the outside with the aim of avoiding foreign
bodies from entering the equipment. In order to
guarantee maximum device performance, the
grid chosen must ensure low pressure loss.
In order to avoid the formation of condensate:
insulate the air discharge pipes and the air duct
cover connections with steam-tight thermal
cladding of an adequate thickness.
If it is considered necessary in order to prevent
flow noise, sound mufflers can be mounted.
