The connection of the return air duct is now very easy, directly
on the air filter accessory.
Filter access for maintenance is ensured by removing the two
Metric screws on the unit side (rear view of the unit).
The cover panel, supplied with a handle, can now be removed.
The filters are attached to each other with a bracket that permits
sliding them into the frames.
10.5.3 - Fan discharge
A square flange is supplied mounted on the unit. An available
standard round flange can easily be installed at the fan discharge,
if the installer prefers the use of a round connection duct.
The unit is supplied with a cover panel on the discharge
side. This panel has to be removed before connection to the
duct system.
30RY-017-033: standard 560 mm diameter fan
30RY-040-080: standard 710 mm diameter fan
It is advisable to make the connection to the duct system with a
flexible collar. If this recommendation is not observed, a lot of
vibration and noise may be transmitted to the building structure.
The unit construction does not permit the support of a duct
weighing more than 10 kg. Non-observance may lead to
damage of the unit.
10.5.4 - Applicable regulations for units used with an air
duct system
Ensure that the return or supply air openings cannot accidentally
be obstructed by panels (for example low return air or opening
of doors).
Unit performances are given for an air-side pressure drop that
is indicated in the Physical Data table.
The three tables that follow contain fan characteristics, maxi-
mum air entering temperatures and performance correction
factors, depending on the air system used with the units.
