2. Your Safety
This appliance is not intended for use by person/s (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and/or knowledge. Unless the person has been given supervision
or instruction concerning the use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance, it is not a toy.
Do not install Isodrive motor to a non-Schweigen and/or non-silent rangehood. If you fail to do so, your
warranty will be voided.
The manufacturer declines all responsibility in case of failure to adopt proper safety measures.
Ensure that the location in which this appliance is installed, has good and permanent ventilation.
Please consult local laws and regulations and install in accordance.
Use an electrical connector with earth that is correct for your location.
Check that the voltage in your area corresponds to the appliance as indicated on the rating label.
Before Installation
We recommend this appliance to be installed or repaired by a qualied Schweigen Home Appliances technician.
Please see our website www.schweigen.com.au for recommended installers.
It is dangerous to modify any part of this appliance. Modication 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 qualied 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.
RECEIVING YOUR RANGEHOOD
Please read this section thoroughly before attempting to operate the appliance.
Inspect your product upon receipt. Any damage or defects MUST be reported
within 48 hours, or no claim will be recognised.
DO NOT INSTALL THIS APPLIANCE IF YOU FIND IT DAMAGED.
If this product is installed damaged, the supplier, nor the retailer, will be responsible
for the costs associated with the repair, replacement, removal or re-installation of
the appliances.

2. Your Safety
This guide is for the installation of the motor used in the Isodrive systems 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 SteelFlex™ducting measurements are referring to inside measurements, unless
otherwise mentioned..
Motor Features
• Universal mounting, all position with IPX4 degree of weather protection.
• Patented anti water intrusion system.
• Super quiet, long vane, backward curved centrifugal fan.
• Airow is dependant on installation and the ducting used. Using a single 150mm SteelFlex™duct, you
should attain up to 650m3/hr depending on the ducting installation. The use of a smaller than 125mm
pipe would result in a loss of airow.
• Simple installation: The motor 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 eciency PSC type and rated at 62W costing around the same as a 60W light globes 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 SteelFlex™duct bell-mouth adaptor.
This fan is suitable for connection to ducting runs with a minimum inlet area of 11,000mm2. 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). SteelFlex™ducting must be extended suciently 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 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 your warranty.
NOTE:Fan module and dual foil Steelex™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 650 motor, recommended minimum 3 metres (approx.) of SteelFlex™ducting and with at least
two bends.
NOTE: Installation closer than this distance may result in higher noise level. Maximum duct length is 4 to 5
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.
Safety of Children
This fan is not intended for use by young children or inrm persons without supervision.
Replacement of Supply Cord
If the supply cord is damaged, it must be replaced by a service agent or suitably qualied 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 ecient 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 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 eect to occur; like a didgeridoo where a noise is
produced at one end of a hollow rigid pipe and the noise is amplied out the other.
The Isodrive 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. 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: 650 motor — 3 metres.
Mount 100mm rigid PVC pipe securely to beams, trusses or other appropriate structures: refer gure 1. The pipe
should be mounted vertically or perpendicular to the roof cladding 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 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 authorised switching mechanism in
bathroom application, refer gure 2.
Fit fan module to mounting ange by placing in position, rotating clockwise to engage bayonet ngers then
secure by screwing in locking screw (while holding fan module rmly in the fully clockwise position), refer gure 2.
Do not install the SteelFlex™in a straight line and minimum of two gentle bends in the ducts is required.

SteelFlex™Safety Ducting
SteelFlex™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 airows. Incorrect installation may reduce airow 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.
