PREPARATIONS FOR INSTALLATION
Installation precautions for flexible, insulated ducts:
• Ensure the network is sealed around the sleeves and connectors by using fixing collars.
• Avoid unnecessary bends.
• Stretch the duct out into straight lines.
• Do not crush ducts, and make sure they are visible so no one else will crush them Dee Fly assembly
Connectors
The motor and heat exchanger casings are equipped with 4 Ø160 mm connectors.
Fresh air intake
Exhaust to outside
To avoid the nuisance of noise transmission, it is imperative that
connections to the motor casing use flexible couplings: flexible sleeves
or ducts.
For maintenance or replacement access to equipment, there must be
hatches that are large enough to permit access to the equipment or the
technical area
To facilitate the mounting of circular flexible ducts and to ensure that
the network is sealed, each connector is fitted with a 160 mm diameter
quick-fit connector. Insulated ducts must be used once the ducts are in
a non-heated volume (for assembly instructions, see page 30)
Attach the inner duct to
the connector using
a collar.
