• Motor is a high efciency PSC type and rated at 62W, costing around the same as a 60W light
globe to run.
• WARRANTY 2 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.
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 sufciently to present
a smooth air passage with bends of at least the radius of twice the diameter of the duct.
WARNING: The Hi Flow VX120 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 Hi Flow VX120 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
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 appliance is not intended for use by children; or inrm persons with reduced physical, sensory or
mental capabilities; or people with lack of experience and/or knowledge, unless given supervision
or instruction concerning the use of the appliance by a qualied person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance; it is not a toy.
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
Someinternetsitesstronglyrecommendtheuseofrigidductingoverfullyexibleducting.Thismay
well be the case with conventional rangehoods with internal motor rangehood.
Schweigen’s unique Hi Flow system works in the opposite way to conventional rangehoods, pulling
air through the hood and acoustically-matched ducting which results in almost silent, high volume
ow. Using a completely rigid or semi-rigid ducting system creates an undesirable ‘organ-pipe’ sound
effect similar to that of a didgeridoo, where noise is produced at one end then amplied at the
other.
The Hi Flow system eliminates any produced noise by externalising it.
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.
