mentioned.
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 150mm exi duct run you should attain 650m
3
/hr depending on the ducting installation.
• The use of a smaller 125 pipe would result in a loss of airow.
• Simple installation: - Mounts onto a 100mm 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 62W, costing around the same as a 60W light globe to run.
• WARRANTY 10 YEARS return to manufacturer. Covers faulty manufacturing or components. It does not cover
normal wear and tear, chemical or storm damage, etc.
General Notes on Installation and Use
This fan unit is designed to be installed using 100mm PVC pipe as the initial connection duct to the fan module,
and is supplied with a 100mm PVC pipe to 150mm exible duct bell-mouth adaptor.
This fan is suitable for connection to multiple duct runs with a minimum inlet area of 11000 mm². Ducting runs
should be more than 2 metres away from the unit and no more than 4 - 5 metres (check with supplier if longer
duct length required). Flexible 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.
WARNING: The Isodrive motor system 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.
NOTE: Fan module and dual foil exi-duct are acoustically matched. Use of semi-rigid or rigid ducting will result
in increased noise and void warranty. See installation instruction notes ‘Why exi-duct’.
Recommended Installation Distance
For Isodrive 650 motor, a minimum of 3 metres (approx.) is recommended.
NOTE: Installation closer than these distances may result in higher air noise level. Maximum duct length 4 - 5
metres. Check with supplier if longer 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 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.
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 puts 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 and may void warranty. A
preferred installer list can be obtained from Schweigen website www.schweigen.com.au or
call 1300 881 693.

Roof Installation (Recommended duct length: 3 metre)
Mount the 100mm rigid PVC pipe securely to the beams, trusses or other appropriate structures, refer gure 1.
The pipe should be mounted either vertical or perpendicular to the roof cladding with the roof penetration
being sealed using a Dektite or other sealing device.
Ensure that the pipe protrudes a minimum of 80mm past the top of the Dektite, checking that the
mounting ange clears the roof cladding at upper edge as shown in gure 1 — Roof Mount Option.
Maximum recommended protrusion is 400mm. Fit mounting ange, refer gure 2, to pipe using silicon sealant,
then tape in position until sealant has set.
Pass power cord and plug through mounting ange and pipe, then out the slotted end of the PVC pipe for
connection to the female plug coming from the canopy/rangehood or authorized switching mechanism in
bathroom application, refer gure 2.

Flexible Duct
Flexible ducting must be fully extended and cut to the required length upon installation, refer to gure 13.
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. Installation should be done by a
qualied technician. A preferred installer list can be obtained from Schweigen website www.schweigen.com.au.
Please keep the exible duct taut,
