SAFETY PRECAUTIONS

READ, FOLLOW AND SAVE THESE INSTRUCTIONS!

1. Only use this fan in a manner intended by the manufacturer
namely as a vertical, ceiling mounted, air moving device. Any
attempt to use this fan for any other purpose without expressed,
written permission from The Humongous Fan Company will
invalidate the warranty.

2. Before servicing or cleaning the fan, all sources of electrical
power must be disconnected. The user should take means to
ensure that the device is not accidentally energized while being
serviced, such as attaching a lockout tag (not included) to the
power supply.

3. If a safety device is removed prior to servicing the fan, it must
be properly reinstalled before re-energizing the fan.

4. Do not replace any parts to this fan with anything other than
authentic Humongous Fan parts. This includes both
mechanical and electrical components.

5. All electrical wiring must conform to the National Electric Code
and all local codes. Code compliance is ultimately the
responsibility of the installer.

6. The fan must be installed in a manner such that there is no
chance for the fan blades to strike a person or object while in
operation.

7. The fan and any supplemental devices must be installed by
qualified personnel. The Humongous Fan Company will not be
responsible for personal injuries or damage to property or
equipment caused by improper installation.

as laid out in this manual. All safety devices and bracing cables

MOUNTING SCENARIOS

The Humongous Fan is designed to be mounted to either a series of
braces spanning two joists or, directly to an I-beam. The mounting
must be sufficiently secure to absorb up to 250 ft-lbs (340 N-M) of
torque, plus an appropriate safety factor. All bolts must be torqued
to the following values:

Table 1

Joist Mounting Scenario

In general, mounting a Humongous Fan between joists is easier than
clamping to a beam, especially if the joists are close together.
Additionally, this type of mounting offers additional flexibility for fitting
the fan between lights and avoiding the flickering caused by fan
blades passing below a lighting fixture.

Since the motor/hub assembly is the heaviest part of the fan
(weighing as much as 75 lbs/33KG), it will take two people to mount.
