Fans – Rigging and Lifting
IMPORTANT
Fans should never be lifted by the housing, motor,
motor cover, windband or accessories.
1. Before lifting, be sure that all shipping materials
have been removed from the fan.
2. Use standard lifting and rigging practices.
3. ALL lifting brackets on each fan must be utilized at
the same time.
4. Fan to be kept level during lifting and installation.
5. Spreader bars are recommended and must span
the fan to prevent damage to the damper section
of the fan by the lifting cables.
6. Always test-lift the fan to check for proper balance
and rigging before hoisting to desired location.
7. Never lift fan in windy conditions.
8. Preparation of roof opening should be completed
prior to lifting fan to the roof.
9. 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.
Fans are to be rigged and moved by the lifting
brackets shown in Figure 1 or by the skid when a
forklift is used. Location of brackets varies by model
and size.
Handle in such a manner as to keep from scratching
or chipping the coating. Damaged finish may reduce
ability of fan to resist corrosion. See coating repair
section of this manual for details regarding touch-up
of damaged surfaces.

Electrical Connections

The electrical supply must be 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
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
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
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
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.
