Roof Installation
Recommended duct length: 1600 motor — 5 to 6 metres.
Mount 150mm (ISD) rigid PVC pipe securely to beams, trusses or other appropriate structures: refer figure 1.
The pipe should be mounted vertically with the roof penetration being sealed using a Dektite or other appropriate
sealing membrane or device.
Ensure that the PVC pipe
protrudes at least 50mm
past the top of the Dektite, checking that the fan assembly
clears the roof cladding at upper edge, refer figure 1 – Roof Mount Option.
Pass power cord and plug through mounting flange and pipe, then out the slotted PVC pipe for connection to the
female plug coming from the canopy/rangehood. Refer to figure 4.
Do not insert plug into socket outlet or switch on until installation has been completed. Fit fan module to pipe and
fix in position using side locking screw.
Certain external installation configurations may cause audible levels of noise to be heard due to the air being
expelled from the motor. To minimize external noise disturbance you can use between 6 to 15 metres of SteelFlex
™
duct to place the Isodrive motor in an appropriate position.
Please be aware that the 1600 motor is capable of expelling air at 1600m

/hr.
For more information on environmental noise limit and conditions please contact your local Council. We have a list
of experienced installers available on the Schweigen website.
Do not install the SteelFlex
™
in a straight line and minimum of two gentle bends in the ducts is required.
