If required by a specific installation, the unit's maximum fan speed
can be configured in the Service Configuration menu. Refer to
the control manual.
The maximum configured speed applies to both the cooling and
heating modes.
The performances (capacity, efficiency, noise level) depend on
the fan speed and the ductwork. Please refer to the manufacturer's
electronic catalogue to evaluate the estimated impact on the
unit's operating conditions.

Specific installation on ductable units
IMPORTANT: In units which are ductable in heating mode,
dehumidification of ambient air, as well as defrosting the air
exchangers, produces a large volume of condensates which
must be dealt with on the unit installation site.
Ductable units must be installed on a waterproof base enabling
efficient drainage and evacuation of the condensate from the
heat exchangers.
Similarly, in case of low outdoor temperatures when air-cooled
exchangers freeze, the water from defrosting must be collected
so as to prevent any risk of flooding the rooms where the heat
pumps are installed.
The rotation speed of all the fans in the same circuit is controlled
in the same way. Therefore each circuit operates independently.
Each refrigerant circuit must have an independent ductwork
system so as to prevent any air recycling between the air-cooled
exchangers of different refrigerant circuits.
On ductable units, each fan is equipped with a factory-fitted
connection interface frame providing a link between the ductwork
itself.

Refer to the dimensional plans of the units for the precise dimensions of the connection interface. A flexible sleeve providing
connection to the ductwork is delivered with the unit.
