Triangle Engineering of Arkansas VAB - Manual

ELECTRICAL CONNECTION
The electrical supply must be compatible
with the fan motor with regard to voltage,
phase and amperage capacity. Moreover, the
electrical supply line must be properly fused
and conform to local and national electrical
codes.
For belt drive units, the electrical supply
line is routed to the optional safety disconnect
switch (if supplied) and then to the motor.
Direct drive units have a prepunched wiring
hole in the fan housing. The electrical supply
may be connected to an optional safety
disconnect switch or a junction box may be
installed for direct connection to the motor
wires.
INSTALLATION, OPERATING AND
MAINTENANCE MANUAL
Model TAD, TAB, VAD and VAB fans
are thoroughly inspected and test run at the
factory, however, damage may occur during
handling and shipping. Consequently, it is
important that the unit be carefully inspected
for visible and concealed damage before
beginning installation. Report any damage to
the shipper immediately. In addition, assure all
accessory items are accounted for.
INSTALLATION
LIFTING
Attach two suitable chains or straps
around the entire tubular fan housing,
one near each duct flange, when lifting
large horizontal mount fans. Secure the
fan housing to prevent the weight of a top
or side mounted motor from rotating the
housing while being lifted.
For vertical hanging installations, attach
a suitable lifting device to the fan housing or
inlet/outlet flange.
The fan should never be lifted by
the motor, belt tube, propeller, shaft or
accessories.
MOUNTING
Tube axial fans for horizontal base mount
are available with rotatable mounting feet as
an optional feature. By removing fasteners
attaching the mounting feet to the inlet and
outlet flanges, the tubular housing may be
rotated to position the motor on either side
or the top of the fan (belt drive units).
In applications where the fan is to be
suspended horizontally or vertically from the
ceiling, optional hanging brackets are welded
to the fan housing. Fans can be suspended
with motors on top or bottom. The installer
must provide suitable rods for hanging
installations.
Triangle Engineering recommends use
of base or hanging vibration isolators on
all tube axial installations. Do not support
ductwork, etc. on isolators designed to
support weight of the fan only.
