11.4.1 - Installation
All fans in the same refrigerant circuit are controlled by a
single speed variator and therefore all run at the same speed.
Each refrigerant circuit (A, B and C) must have a separate
ducting system to prevent any air recycling between the
condensers of the different refrigerant circuits.
In 30RB units with option 12 each fan is equipped with a
factory-installed connection interface, allowing the connec-
tion to the ducting system for the specific circuit (A, B and
C) for each fan. Please refer to the unit dimensional draw-
ings for the exact dimensions of the connection interface.
