2. Your Safety
This guide is for the installation of the Isodrive motor system after the canopy/rangehood has been
mounted on the wall or ceiling. (Refer to canopy/rangehood 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 250mm ex duct, you
should attain up to 3200m3/hr depending on the ducting installation. The use of a smaller than
250mm (ISD) pipe would result in a loss of airow.
• Simple installation: mounts onto a 250mm 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 efciency PSC type and rated at 150W 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.
General Notes on Installation and Use
This fan unit is designed to be installed using 250mm (OSD) PVC pipe as the initial connection to the
fan module. The fan unit is supplied with a 250mm (OSD) PVC pipe, 250mm (ISD) exible duct. (See
page 10 for installation detail).
This fan is suitable for connection to multiple duct runs with a minimum inlet area of 22,000mm2 and
length up to 15 metres maximum (check with supplier if longer duct length required). Where possible
exible ducting must be extended sufciently 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.
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 3200 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 15 metres (use 250mm ducting), however please be aware that
increasing the duct length above 5m will decrease airow. Check with supplier if longer duct length
is required. Do not reduce the duct size at any time and avoid sharp bends.
