should attain up to 900m
/hr depending on the ducting installation. The use of a smaller than 200mm
ducting would result in a loss of airow.

ducting must be extended
suciently to present a smooth air passage with bends of at least the radius of twice the diameter of the duct.
Excessive bends in the ducting will compromised extraction.

It is reproof, pest and crush proof with a treated surface that prevents the build-up of grease
and bacteria.
Schweigen’s unique Isodrive system works in the opposite way to conventional rangehoods, pulling air through
the hood and acoustically matched ducting, producing almost silent high volume ow. The use of a complete
rigid or semi-rigid ducting system will allow an organ piping eect to occur; like a didgeridoo where a noise is
produced at one end of a hollow rigid pipe and the noise is amplied out the other.

4. Installation
Roof Installation
Recommended duct length: 900 motor — minimum 4 metres.
Mount 150mm (ISD) rigid PVC pipe securely to beams, trusses or other appropriate structures: refer gure 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 a minimum of 50mm past the top of the Dektite, checking that the fan
assembly clears the roof cladding at upper edge as shown in gure 1 — Roof Mount Option.
Pass power cord and plug through mounting ange and pipe, then out the slotted PVC pipe for connection to the
socket coming from the canopy/rangehood. Refer to gure 4.
Do not insert plug into socket outlet or switch on until installation has been completed. Fit fan module to pipe and
x in position using side locking screw.
Certain external installation congurations 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 4 to 8 metres of SteelFlex
duct to place the Isodrive motor in an appropriate position.

Please be aware that the 900 motor is capable of expelling air at 900m
/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.
