A. Unpacking:
Be careful not to damage or deform any parts of the blower when removing it from the packaging container. All the
packaging material should be kept in the event the blower needs to be returned.
Handling:
Handling of the blower 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 blower should
be lifted using well-padded chains, cables or lifting straps with spreader bars. Some blower models have lifting eye
locations provided in the blower base. NEVER
lift the blower by an inlet or discharge flange, blower shaft, or
any other part of the blower assembly that could cause distortion of the blower assembly.

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 blower.

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