PLANNING THE INSTALLATION
1. Locate the inline fan so that the length of the duct run and
number of elbows needed is kept to a minimum.
2. The inline fan is designed for use with 10" diameter duct.
3. Use rigid metal ductwork.
4. Always install ventilation products with an approved wall
or roof cap.
5. For a truly quiet kitchen ventilation system add a Viking
Inline Duct Silencer part number VSIL10 (sold separate-
ly) to the installation. The simple addition of a inline duct
silencer between the range hood and the VIL900 fan can
typically reduce the perceived sound level of the system
by more than 50%.
MOUNTING THE VIL900 INLINE FAN
To minimize any potential vibration noise it is recommended
that the inline fan be mounted with Viking Vibration Isolation
Kit part number ILVK (sold separately).
