3 - INSTALLATION SPECIFICS FOR 30RQSY UNITS
3.1 - General
Each fan is controlled by a variable-speed controller. Therefore
each circuit operates independently and must have a separate
duct system to avoid any air recycling between the air heat
exchangers of the different refrigerant circuits.
On the 30RQSY units each fan includes a factory-mounted
connection frame interface for the connection to the duct network
of the specic refrigerant circuit to which the fan belongs.
For the precise dimensions of this connection interface please
refer to the dimensional drawings for the units.
3.2 - Duct connection
30RQSY units can be installed inside a building and connected
to a air distribution duct network:
- Air heat exchanger side, at the fresh air suction side for
30RQSY 039 to 078 units
- Fan discharge side at the evacuation side of the treated air
by the unit heat exchanger (30RQSY 039 to 160).
For the precise dimensions of this connection interface please
refer to the dimensional drawings for the units.

3.2.1 - Standard unit suction connection
30RQSY 039 to 078 units are supplied with a sleeve that allows
connection of an air heat exchanger suction duct. Provide a
removable window on the suction duct to allow the maintenance
of the sensor (see gure above).
For units 30RQSY 050 to 078 the air heat exchanger is on two
unit sides. It is therefore necessary to install two additional brackets
to allow connection of the heat exchanger suction duct.
These parts are inside the machine and xed to the riser (as shown
on the diagram below) with plastic collars.
