CONNECTING DUCT WORK TO VIL900 INLINE FAN
Two duct clamps part number 001377-000 are included
with this duct and are intended to simplify fan installation
and isolate fan vibration from the rigid metal duct.
Note: The duct clamps are
convenient in installations
where regular removal of the
fan in necessary for inspec-
tion and cleaning.
The built in hanger tab of the duct clamps are not intended to
support the weight of the inline fan. The inline fan should be
supported with the integral brackets of the inline fans.
If special supports are required in anticipation of earthquakes
the duct clamps that are supplied with the VIL900 are not
intended to meet these requirements.
To minimize vibration, leave a 1/4” gap between the inline fan
collars and rigid duct.
Tighten the two screws until the fan and duct are snugly attached.
The duct work at the inlet of the inline fan is to be connected
to the rough-in plate.
The duct work at the out box of the inline fan is to be con-
nected to a roof or wall cap.
A inline butterfl y damper part number PV300006 is included
with the VIL900. The damper can be installed anywhere in
the duct system. Damper must be installed so that the air-
fl ow direction will open the butterfl y blades. Mounting the
damper in an inverted position may prevent the blades from
closing completely. The preferred installation position is ver-
tical as shown below.
USE AND CARE
Disconnect electrical power supply and lock out service panel
before cleaning or servicing this unit.
CLEANING
Periodic inspection and cleaning is recommended. The fre-
quency of inspection and cleaning should be adjusted accord-
ing to the type and amount of cooking.
The interior of the fan can to accessed by removing the duct
clamp and gently moving the duct work away from the inlet
of the fan.
If excess build up is present it should be removed from the
interior of the fan and from the impeller of the fan.
MOTOR LUBRICATION
The motor is permanently lubricated. Do not oil or disas-
semble motor.
