8. Flexible duct
Flexible Duct
Flexible ducting must be fully extended and cut to the required length upon installation, refer to
figure 13. Maximum fan performance will not be achieved unless the ducting is fully extended. Failure
to fully extend ducting results in a smaller air passage and lower airflows. Incorrect installation may
reduce airflow or increase noise levels. Call outs relating to incorrect installation will result in a service
fee directed to the customer. schweigen will take no responsibility for problems caused by faulty
installation. Installation should be done by a qualified technician. A preferred installer list can be
obtained from schweigen website www.schweigen.com.au.
Please keep the flexible duct taut,
3 metres in length (recommended)
NoTE: in shallow roof spaces
extend flexible duct horizontally
