Fig. 5 – Example of an air outlet duct
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;
•
The maximum total allowable pressure drops for all components, including through holes for mounting on external wall,
within the pipe system must not exceed 77 Pa.
All Technical parameters shown in the table above, are guaranteed at air flow rate 315 m
98Pa. So Please keep the following rules:
Use airduct pipe system with diameter Ø160mm
1.
2. Maximum length of both inlet and outlet straight pipes must not exceed 12 meters!!!
3. Each elbow 90
4. Elbow 45
Examples:
o
four elbows 90 + 4m straight pipes, or two elbows 90
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.
Fit the pipes, the wall through holes and the connections to the heat pump with vibration damping
systems.
WARNING! the simultaneous operation of an open-flue firebox (e.g. an open-flue fireplace) together with the heat
pump causes a dangerous environmental pressure drop. This could cause the backflow of exhaust gas into the
environment itself.
Do not operate the heat pump together with an open-flue firebox.
Use only sealed-chamber fireboxes (approved) with a separate duct for combustion air.
Keep the doors to the boiler room closed and hermetically sealed if they do not have a combustion air supply in
common with inhabited areas.

5.3. Particular installation conditions

One of the peculiarities of the heat pump heating system is represented by the fact that these units cause a
considerable reduction of the air temperature that is generally ejected from inside the home. Apart from being colder than the
ambient air, the exhaust air is also completely dehumidified; for this reason, it is possible to allow the air to flow back into the
home in order to cool specific environments or rooms during the summer.
Installation consists of the splitting of the discharge pipe to which two shutters are applied with the aim of directing
the air flow either towards the outside or the inside of the home (Fig. 6a, 6b).
