PREPARATIONS FOR INSTALLATION
Connectors
tors.
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.
Attach the insulator and the outer duct
and tighten it with the fixing collar
Make sure the duct is properly fitted
and sealed.

FLOW RATE SELECTION
(Only for the Dee Fly high efficiency version)
The choice of air flow rate is dependant on the number
of ‘wet rooms’ – shown in the table above.
The selection is made be a switch on the back
of the Dee Fly controls. Simply position the jumpers as
shown below to obtain
the required basic
airflow rate:
