9.4 REQUIRED SERVICE SPACE

Below you will find the minimum space required to be able to complete service and maintenance tasks on the units.
Moreover, re-circulation of discharge air has to be avoided; failure to observe this point will result in poor performance or
activation of safety controls. For these reasons it is necessary to observe the following clearances.
If air inlet and/or outlet pipes are connected, portion airflow and capacity in heat pump unit will lose.
If the unit connects with air ducts it should be DN 160 mm for pipes or 160 mm internal diameter flexible hose. Total
length of the ducts should not be longer than 4 m or the maximum static pressure should not exceed than 60 Pa. If
the air ducts are bended, the pressure loss will be larger. So if there are 2 bending pipes, the total length of the
ducts should not be longer than 2m.
Please note that the performance of the unit are reduced in the case the air inlet is connected to a duct which takes
air from outside, because of the low winter temperatures and high summer temperatures.
The optimal working ambient temperature is 20°C.
In the table on this side, the max lenghts of air
piping are reported, depending on the geometry
(original 180 mm) and if the installer need to
increase the diameter to 180 mm.
