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.
3
/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 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 (ISD) exible duct bell-mouth adaptor.
2
This fan is suitable for connection to multiple duct runs with a minimum inlet area of 22,000mm
to 10 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 10 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.

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 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 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 6 to 10 metres of exi duct
to place the Isodrive motor in an appropriate position.

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 recommended installers available on the Schweigen website.

Wall Installation
This type of installation is similar to roof mounting, ensuring that the pipe extends at least 50mm past the wall
surface refer gure 2. If the pipe length is shortened, reproduce the power cord exit slot on the inside of the
wall.
NOTE: By decreasing the length of the exi 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.

6. 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 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 preferred Schweigen installers can be
obtained from the Schweigen website www.schweigen.com.au.
Page 17
6. Flexible Duct
Shallow Roof Space
In shallow roof spaces, do not crush or kink exible ducting, as it will reduce air ow severely. 90 degree curve
made of PVC or galvanise can be used as a substitute for the bend, refer to gure 12.
90 degree curve PVC or
galvanise curve

6. Flexible Duct
Securing Flexible Duct
Flexible duct must be installed with supports at maximum intervals of 1.5 metres. Flexible ductwork can be
supported by using gaer 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.
Option 1
Secure the exible duct
to the beam
Option 2
Support exible duct
by using hangers.
NOTE: Care shall be
taken to minimize
sagging or snaking
of the duct between
supports.
