I. GENERAL

A. Unpacking:

Be careful not to damage or deform any parts of the fan when removing it from the packaging container.

All the

packaging material should be kept in the event the fan needs to be returned.

Handling:

Handling of the fan should be performed by trained personnel and be consistent with all safe handling practices.
Verify that all lifting equipment is in good operating condition and has the proper lifting capacity. The fan should be
lifted using well-padded chains, cables or lifting straps with spreader bars. Some fan models have lifting eye
locations provided in the fan base.

NEVER lift the fan by the motor shaft, motor eye bolt, or any other part of

the fan assembly that could cause distortion of the fan assembly.

B. Safety Instructions & Accessories:

1. Safety Instructions:

All installers, operators and maintenance personnel should read AMCA Publication 410-96,

“Recommended Safety

Practices for Users and Installers of Industrial and Commercial Fans”.

This manual is included with the fan.

Additional copies can be requested by writing us at Cincinnati Fan, 7697 Snider Rd., Mason, OH 45040-9135

2. Sound:

Some fans can generate sound that could be hazardous to personnel. It is the responsibility of the user to measure the
sound levels of the fan and/or system, determine the degree of personnel exposure, and comply with all applicable
safety laws and requirements to protect personnel from excessive noise.

3. Air Pressure and Suction:

In addition to the normal dangers of rotating machinery, the fan can present additional hazards from the suction or pres-
sure created at the fan inlet or discharge. Suction at the fan inlet can draw materials into the fan where they become high
velocity projectiles at the discharge and cause severe personal injury or death. It can also be extremely dangerous to per-
sons in close proximity to the inlet or discharge as the forces involved can overcome the strength of most individuals.
