2. Your Safety
This guide is for the installation of the Isodrive motor system after the canopy/rangehood or bathroom
extraction grill has been mounted on the wall or ceiling. (Refer to canopy/rangehood or bathroom extraction
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.
• Airow is dependant on installation and the ducting used. Using single 200mm ex duct, you should attain
up to 900m
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.

/hr and depending on the ducting installation. The use of a smaller than 150mm (ISD) pipe
• 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 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 150mm (ISD) PVC pipe as the initial connection duct to the fan
module, and is supplied with a 150mm (ISD) PVC pipe to 200mm (ISD) exible duct bell-mouth adaptor.

This fan is suitable for connection to multiple duct runs with a minimum inlet area of 22,000mm
to 15 metres maximum (check with supplier if longer duct length required). Where possible exible ducting must
be extended suciently 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.
and length up
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 900 motor, recommended 4 to 5 metres of exi ducting.
NOTE: Although less than 4 to 5 metres will increase extraction power this will result in higher noise level.
Maximum duct length 15 metres. 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
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 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. 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 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 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.
