Units with fans with available pressure
(Option 12)
The design of this range using R32, is intended for outdoor
installation. More more details on the various installation scenarios,
refer to the installation guide for A2L refrigerants. Units with fans
with available pressure are designed to be ducted to the fan
discharge which results in pressure drops in the air circuit.
It is for this reason that more powerful fan motors are installed for
this option.
For each installation, the duct pressure drops differ, depending
on the duct length, the duct section and the changes in direction.
Ductable units equipped with this option are designed to operate
with ducts whose air evacuation generates a maximum pressure
drop of 200 Pa.
Using a speed variation up to 19 rps enables the system to
overcome the pressure drops in the ducts while maintaining an
optimised air flow in each circuit.
All the fans in the same circuit run at the same time at the same
speed.
In the cooling/heating mode, the full load or part load speed is
controlled by a patented algorithm that permanently optimises the
condensation/evaporation temperature to ensure the best unit
energy efficiency (EER/COP) whatever the operating conditions
and pressure drop of the duct network.
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 duct network. Please refer to the
manufacturer's electronic catalogue to evaluate the estimated
impact of the ducting system on the unit's operating conditions.
12.2.7.1 -
Specific installation in ductable units
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 network of ducts
to prevent any recycling of air 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 duct
network itself and the refrigerant circuit to which the fan belongs.
Refer to the dimensional plans of the units for the precise
dimensions of this connection interface.
Please refer to the chapter ‘‘Arrangement of fans’’ to assign each
fan to their own circuit.
Specific data 30RQP
IMPORTANT: When the 30RQP units operate in heating mode,
dehumidification of the air and defrosting of the air heat
exchangers generate a large amount of condensate that must
be evacuated from the unit installation site.
30RQP units must be installed on a waterproof base enabling
efficient drainage and evacuation of the condensate from the
exchangers.
At low ambient temperature, when the exchangers form frost,
the defrost water must be collected to ensure that there is no
risk of flooding of the area where the units are installed.

(1) The rated air flow rate is set in accordance with Eurovent 12/7 - 35 °C, with an
operating pressure of 160 Pa.
(2) The maximum air flow rate corresponds to the maximum obtainable by these
fans (maximum speed, operating pressure = 0 Pa)
These values are given for illustrative purposes only. The actual and up-to-date
flow rates based on the condition are indicated via the selection on the electronic
catalogue.
