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.
