Greenheck Tube Axial Upblast Fans TAUB-CA Installation And Operation Manual

INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Greenheck Model TAUD, TAUB-CA and TAUB 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 present.
INSTALLATION
LIFTING -
Attach a suitable chain or strap to the points depicted in
Fig. 1. The fan should never be lifted by the motor, tie down points, belt
tube, damper frame, windband or accessories.
Carefully lift the fan to the roof curb and install fasteners in all holes
provided in the unit base. The windband need not be removed for the
lifting operation.
ELECTRICAL CONNECTIONS -
compatible with the fan motor voltage, phase and amperage capacity.
The electrical supply line must be properly fused and conform to local
and national electrical codes.
For direct drive units, the electrical supply may be routed internally
and exit through a hole provided in the fan housing if an optional service
disconnect switch is provided.
For belt drive units, the electrical supply line may be routed internally
and exit the fan housing through a hole provided below the belt tube
opening. The electrical supply line should then be either: (1) connected
to an optional service disconnect switch, or (2) wired directly to the
motor.
For belt drive units in continuous high temperature installations,
the electrical supply must be kept out of the airstream. This means
bringing the supply lines off the roof deck not through the fan. The
electrical supply line should then be either: (1) connected to an optional
service disconnect switch, or (2) wired directly to the motor.
For belt drive units in emergency smoke removal installations, the electrical supply must be kept out of the airstream.
They may also require an isolated power supply so that if power is cut to the building in the event of a fire, the fan will continue
to operate. Check the local and national electrical codes for emergency smoke removal fans.
Disconnect and secure to the "off" position all electrical power to the fan prior to inspection or
service.
Caution must be used when working around the fusible link damper lifters. They contain preloaded
springs and may open the dampers unexpectedly.
Models TAUD and TAUB-CA may have fusible link damper lifters. All model TAUB units designed
for emergency smoke operation have fusible link damper lifters. TAUB fans UL listed as "Power
ventilators for smoke control systems" in sizes 42, 48, 54 and 60 have extra heavy duty fusible
link damper lifters under high spring tension that, for safety reasons, must be pinned to prevent
accidental release during inspection or service. See page 2 for details on how to secure the lifter
arms.
FAILURE TO COMPLY WITH THESE SAFETY PRECAUTIONS MAY
The electrical supply must be
