2. Your Safety
This manual is for the installation of the motor systems use for bathroom and general extraction.
Motor Features
• Universal mounting all position with IPX4 degree of weather protection
• Patented anti water intrusion system.
• Acoustic dome with super quiet, long vane, backward curved centrifugal fan.
• Airow is dependant on installation and the ducting used.
• Using a single 200mm exi duct run you should attain 900m
• The use of a smaller 200mm ducting would result in a loss of airow.
• Simple installation: - Mounts onto a 150mm 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 eciency PSC type and rated at 57W.
• WARRANTY 5 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 150mm (ISD) PVC pipe as the initial connection duct to the fan
module, and is supplied with a 150mm (ISD) PVC pipe to 200mm duct bell-mouth adaptor.
This fan is suitable for connection to ducting runs with a minimum inlet area of 22,000mm
8 metres maximum (check with supplier if longer duct length required). 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.
WARNING: The exhaust fan 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 your warranty.

and length up to
Recommended Installation Distance
Isodrive 900 motor, recommended 4 metres of ducting and with at least two bends.
NOTE: Installation closer than this distance may result in higher noise level. Maximum duct length is 8 metres.
Check with supplier if longer duct length is required. Do not reduce the duct size at any time and avoid
sharp bends.

3. General
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 oor/ground level.
Avoidance of Back Flow
Care should be taken to avoid the back ow of gases into the room.
Safety of Children
This fan is not intended for use by young children or inrm persons without supervision.
Replacement of supply cord
If the supply cord is damaged, it must be replaced by a service agent or suitably qualied person in order
to avoid a hazard.
Why Flexi-duct
Some internet sites strongly recommend the use of rigid ducting over fully exible ducting.
The use of a complete rigid or semi-rigid ducting system will cause 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.
The motor system puts the noise outside the house.
Warning: Installation without the use of at least the minimum recommended length of acoustically matched
exi-ducting will void performance expectations. Any installation problems 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. Faulty installation may void warranty. An experienced
installer list can be obtained from the Schweigen website www.schweigen.com.au or call 1300 881 693.

4. Installation
Roof Installation
Recommended duct length: 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. 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 duct to
place the Isodrive motor in an appropriate position.
3
Please be aware that the 900 motor is capable of expelling air at 900m
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 duct in a straight line and minimum of two gentle bends in the ducts is required.
