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 PVC pipe and SteelFlex
™
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 SteelFlex
™
duct, you should
attain up to 1600m
3
/hr. The use of a smaller than 200mm ducting would result in a loss of
airow.
• Simple installation: The motor mounts onto a 150mm 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 155W costing around the same as two 70W 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. (see warranty card for more information).
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) SteelFlex
™
duct bell-mouth adaptor.
This fan is suitable for connection to ducting runs with a minimum inlet area of 22,000mm
2
and length up to 10
metres maximum (check with supplier if longer duct length required). Where possible 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 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 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 1600 motor, recommended 5 to 6 metres of SteelFlex
™
ducting and with at least two bends.
NOTE: Installations less than 5 to 6 metres will increase extraction power this will result in higher noise level.
Maximum duct length is 10 metres. Check with supplier if longer duct length is required. Do not reduce the duct
size at any time and avoid sharp bends.
