Please see our website www.schweigen.com.au for experienced installers.
It is dangerous to modify any part of this appliance. Modication of any kind, will immediately void the warranty.
Electrical Cord
Ensure the supply cord is not exposed to heat, chemicals or sharp objects. If the supply cord is damaged, it must be
replaced by the manufacturer, service agent or a similarly qualied person in order to avoid a hazard. The power
supply cord connection MUST BE installed in such a way that access is easy in case of emergency.

2. Your Safety
This guide is for the installation of the Isodrive motor system after the rangehood has been mounted on the
wall or roof. (Refer to rangehood installation manual on how to install the rangehood).
NOTE: All pipe and SteelFlex
™
ducting measurements are referring to inside measurements, unless otherwise
mentioned.
Isodrive® Motor Features
• Roof and wall mounting with IPX4 degree of weather protection.
• Patented anti water intrusion system.
• Super quiet, long vane, backward curved, German-made centrifugal fan.
• Airow is dependant on installation and the ducting used. The motor has the equivalent performance of
a 1100 m
3
/h internal motor rangehood when ducted out to the atmosphere. The result is based on the
German DIN and European EN IEC 61591:2020+A11 testing criteria for rangehood performance and is focus
on the removal of contaminants from the kitchen to the external atmosphere. The use of a smaller than
200mm ducting would result in a loss of airow.
• Simple installation: The motor mounts onto a 200mm metal 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 10 YEARS. Covers faulty manufacturing or components. It does not cover normal wear and
tear, chemical or storm damage etc. (see warranty card for more information).
General Notes on Installation and Use
This fan unit is for external use only, with only ducting from the inlet side using supplied 200mm metal pipe as
the initial connection duct to the fan module, and 200mm SteelFlex™ duct.
This fan is suitable for connection to ducting runs with a minimum inlet area of 22,000mm
2
and length up to
8 metres maximum (check with supplier if longer duct length required). SteelFlex
™
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 motor must not be put 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.
NOTE: Fan module and Steelex
™
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 Schweigen SteelFlex
™
Safety Duct’.
Recommended Installation Distance
Isodrive 950 motor, recommended 4 metres of SteelFlex
™
ducting and with at least two gentle 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.
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. Exhaust fans may adversely aect the safe operation of appliances burning gas or other
fuels (including those in other rooms) due to back ow of combustion gases. These gases can potentially
result in carbon monoxide poisoning. After installation of an exhaust fan such as a partition fan or a duct fan
the operation of ued gas appliances should be tested by a competent person to ensure that back ow of
combustion gases does not occur.
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 Schweigen SteelFlex
™
Safety Duct
Schweigen SteelFlex
™
is an ultra-strong and exible high-performance safety ducting made
of Shirikon Firemesh
®
– a tri-layer tear-resistant UV-treated sleeve. Both are developed by
Schweigen – the Silent Rangehood specialists, for quiet and ecient high-volume transfers
of temperature-sensitive air. Engineered to enhance the health and safety of your home,
Schweigen SteelFlex
™
is antimicrobial treated, thermally insulated and acoustically dampened.
It is reproof, pest and crush proof with a treated surface that prevents the build-up of grease
and bacteria.
Schweigen’s unique Ecodrive 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 Ecodrive system places the noise outside the house.
WARNING: Installation without the use of at least the minimum recommended length of acoustically matched
SteelFlex
™
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.
An experienced installer list can be obtained from Schweigen website www.schweigen.com.au or by

Roof Installation
Recommended duct length: 950 motor — 4 metres.
Mount 200mm metal 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 (not provided).
Ensure that the pipe protrudes at least 80mm past the top of the Dektite, checking that the fan assembly
clears the roof cladding at upper edge, refer gure 1 – Roof Mount Option.
Pass power cord and plug through pipe, then out the slotted pipe for connection to the socket 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 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.
For more information on environmental noise limit and conditions please contact your local Council.
For installation, we have a list of experienced installers available on the Schweigen website.
Do not install the SteelFlex
™
in a straight line and a minimum of two gentle bends in the ducts is required.

Wall Installation
This type of installation is similar to roof mounting, ensuring that the pipe extends at least 55mm past the wall
surface refer gure 3. If the pipe length is shortened, reproduce the power cord exit slot on the inside of the
wall.
IMPORTANT FOR 950 MOTOR: Weather shield must be tted to the top cover of the side ange using the 3
screws provided. Also, it is required to use the hanging bracket for wall mount installation, for more information
please refer to page 11.
NOTE: By decreasing the length of the SteelFlex
™
duct from which specied (refer to installation instructions)
there will be an increase in airow and noise levels as a result. This increase in airow can cause movement of
air to be heard through the system and inhibit the system to run silently.

safety 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 airows. Incorrect installation may reduce airow 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 experienced installers can be
