Page 5
This guide is for the installation of the Isodrive motor system after the canopy/rangehood has been mounted
on the wall or ceiling. (Refer to canopy/rangehood unit installation manual).
NOTE: All PVC pipe and exi ducting measurements are referring to inside measurements, unless otherwise
mentioned.
Motor Features
• Roof and wall mounting with IPX4 degree of weather protection.
• Super quiet, long vane, backward curved centrifugal fan.
• Airow is dependant on installation and the ducting used. Using single 250mm ex duct, you should attain
up to 3200m3/hr depending on the ducting installation. The use of a smaller than 250mm (ISD) pipe would
result in a loss of airow.
• Simple installation: mounts onto a 250mm PVC pipe for ultimate strength and allows for easy Dektite roof
sealing.
• Industrial quality motor and fan made in Germany and rated at 40,000 hours.
• Motor is a high eciency PSC type and rated at 150W costing around the same as two 70W light globes to
run.
• WARRANTY 10 YEARS return to manufacturer. Covers faulty manufacturing or components. It does not
cover normal wear and tear.
General Notes on Installation and Use
This fan unit is designed to be installed using 250mm (OSD) PVC pipe as the initial connection to the fan module.
The fan unit is supplied with a 250mm (OSD) PVC pipe, 250mm (ISD) exible duct. (See page 10 for installation
detail).
This fan is suitable for connection to multiple duct runs with a minimum inlet area of 22,000mm2. When
installing, 15 metres of 250mm exi ducting MUST be used and no more than 2 to 3 bends in the exi ducting.
Where possible exible ducting must be extended suciently to present a smooth air passage with bends of at
least the radii of twice the diameter of the duct.
WARNING: The rangehood must not be ducted into a wall cavity or a ceiling space, where a build up of grease
can occur and become a potential re risk. This will void warranty.
NOTE:Fan module and dual foil exi-duct are acoustically matched. Use of semi-rigid or rigid ducting will result
in increased noise and may void warranty. See installation instruction notes ‘Why exi-duct’.
Recommended Installation Distance
Isodrive 3200 motor, recommended 4 to 5 metres of exi ducting.
NOTE: Although less than 4 to 5 metres will increase extraction power this may result in a higher air noise
level. Maximum duct length 15 metres (use 250mm ducting), however please be aware that increasing the
duct length above 5 metre will decrease airow. Check with supplier if longer duct length is required. Do
not reduce the duct size at any time and avoid sharp bends.
2. Your Safety

Page 6
Minimum Mounting Height
This fan unit is intended for mounting at a minimum height of 2.1 metres (measured to the lower part of the
fan impeller) above a oor or the ground.
Avoidance of Back Flow
Care should be taken to avoid the back ow of gases into the room from the open ue of gas or other open re
appliances.
Safety of Children
This fan is not intended for use by young children or inrm persons without supervision.
Replacement of supply cord
If the supply cord is damaged, it must be replaced by a service agent or suitably qualied person in order to
avoid a hazard.
Why Flexi-duct
Some internet sites strongly recommend the use of rigid ducting over fully exible ducting. This
may well be the case with conventional rangehoods with internal motor rangehood but not with
external motor rangehood.
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 eect to occur; like a didgeridoo where a noise is
produced at one end of a hollow rigid pipe and the noise is amplied out the other.
The Isodrive system places the noise outside the house and it needs to be kept there.
WARNING: Installation without the use of at least the minimum recommended length of acoustically matched
exi-ducting in the system will void performance expectations. Any installation problem must be reported
to Schweigen. Call outs relating to incorrect installation will result in a service fee direct to the customer.
Schweigen takes no responsibility for problems caused by faulty installation, this may void warranty. A
preferred installer list can be obtained from Schweigen website www.schweigen.com.au or by calling
1300 881 693.

Roof Installation
Recommended duct length: minimum 4 metres, optimal 4-5 metres.
Mount 250mm (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 when installing through a metal nished roof. DO NOT install on a over lapping join.
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 gure 1.
Pass power cord and plug through mounting ange and pipe, then out the slotted PVC pipe for connection to the
female plug coming from the canopy/rangehood. Refer to gure 1.
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 congurations 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 5 to 15 metres of exi duct
to place the Isodrive motor in an appropriate position.
Please be aware that the 3200 motor is capable of expelling air at 3200m3/hr.
For more information on environmental noise limit and conditions please contact your local Council. We have a list
of recommended installers available on the Schweigen website.

5. Flexible Duct
Flexible Ducting
Flexible ducting must be fully extended and cut to the required length upon installation. 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 airows. Incorrect installation may reduce airow 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. A list of preferred Schweigen installers can be
obtained from the Schweigen website www.schweigen.com.au.
Please keep the exi ducting taut,
4 to 5 metres in length is optimal
NOTE: In shallow roof spaces
extend exi ducting horizontally

Securing Flexible Duct
Flexible duct must be installed with supports at maximum intervals of 1.5 metres. Flexible ductwork can be
supported by using gaer or electrical tape. Provided that it does not restrict the internal diameter of the
ducting. Ducting installed looped over hanging beams should be installed in such a manner as to ensure the
changes of direction are gradual. Support of the ducting with the use of hangers may be required, see option 2.
NOTE: Ducting should be kept taut at all times.
