INTRODUCTION
This manual has been prepared to guide the users of
heavy duty composite fiber fans in the proper installation,
operation, and maintenance procedures to insure maxi-
mum equipment life with trouble-free operation. These
fans are made from a corrosion resistant reinforced plas-
tic (FRP). It is the responsibility of the purchaser, install-
er, and user to provide qualified personnel experienced in
the installation, operation, and maintenance of composite
fiber air moving equipment.
Since many fans of this type have custom features or
components, please refer to the attached appendices for
additional information. When manufacturers of compo-
nents provide detailed installation and operation manuals,
they will be provided. Because of the wide variety of
equipment covered in this manual, the instructions given
here are general in nature.
Additional product and engineering information is avail-
able at www.aerovent.com.
For safe installation, startup, and operational life of this
equipment, it is important that all involved with the equip-
ment be well versed in proper fan safety practices and
read this manual. Please review the safety section before
beginning any work. It is the user’s responsibility to make
sure that all requirements of good safety practices and
any applicable safety codes are strictly adhered to.
SHIPPING and RECEIVING
All Aerovent products are carefully constructed and
inspected before shipment to insure the highest stan-
dards of quality and performance. Compare all compo-
nents with the Bill of Lading or Packing List to verify
that the proper unit was received. Check each unit for
any damage that may have occurred in transit. Any
damage should be reported immediately to the carrier
and the necessary damage report filed.
HANDLING
Handling of all air moving equipment should be con-
ducted by trained personnel and be consistent with safe
handling practices. Verify the lift capacity and operating
condition of handling equipment. Maintain handling
equipment to avoid serious personal injury.
Units shipped completely assembled may be lifted
with slings and spreader bars. (Use well-padded chains,
cables, or nylon straps.) On most units, lifting lugs are
fashioned to protect the fan and fan housing from dam-
age. Never lift a fan by the inlet or discharge flange,
shafting or drives, wheel or impeller, motor or motor
base, or in any other manner that may bend or distort
parts. Never lift with slings or timbers passed through
the fan inlet.
Partial or disassembled units require special handling.
All composite parts should be handled in a fashion
which protects the laminate structure plus its outer gel
coat surface from damage. All composite parts should
be handled such that forces are not concentrated to
avoid bending or distortion. Never allow the outer gel
coat surface to be damaged due to any sudden impact
forces or any stress that may cause the gel coat to be
cracked.
The fan housing should be lifted using straps and
spreaders. Do not distort the fan housing (scroll and side
plates) when lifting.
Bearing pedestals should be lifted using straps or
padded chains. Under no circumstances should an
attached or separated bearing pedestal be lifted by the
shaft, bearings, drives, motor, or impeller.
The single width shaft and wheel sub-assembly may
be lifted using a hoist with a sling around the shaft at
a point nearest the wheel. Take care not to scratch the
shaft where the bearings or drive will be mounted. Never
lift or support the sub-assembly by the wheel. Never lift
the shaft and wheel sub-assembly by the wheel blades,
wheel cone, or the wheel back plate. Always support
the sub-assembly by the shaft when lifting or storing.
