3.2.4.
Connecting the air duct to the unit
-
The diameter of the socket of the unit for connection of the distribution pipe is 125 mm. The sockets are
fitted with a rubber gasket for better sealing of the joint and a thermal sleeve for better connection of the
pipe insulation to the neck (thermal bridge breaking).
-
Connect the pipe to the sockets up to the heat sleeve on the socket.
-
Seal the joints with aluminium tape or connecting sleeves to prevent vibration transmission.
-
Insulate the pipes with thermal insulation material (rock wool, butyl rubber etc...).
-
Pull the pipe insulation at the socket over the heat sleeve at the socket and secure against any undesired
movement.
-
All the pipe joints that are connected to the unit must be sufficiently sealed to prevent unwanted leaks
and subsequent problems such as condensation.
-
The connected piping must be of the same diameter as the unit's connecting sockets. If smaller diameter
piping is used, this may affect the air performance of the unit and may reduce the life of the fans.

General Information – Safety
-
Before starting all the installation work, make sure that the wiring box or mains power outlet that you
want to use to connect the unit is equipped with a protective (green-yellow) wire or contact (pin).
-
If you use a mains plug to connect the unit, it must always remain accessible
so that the unit can be
safely disconnected from the mains in the event of danger.
-
Check that the power supply meets the requirements for power supply of the unit (voltage, current,
frequency, etc.) specified on the unit's serial plate. Section 3.3.3. Displaying the Electrical Parameters.
