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.tcf.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 Twin City Fan & Blower products are carefully

constructed and inspected before shipment to insure the

highest standards of quality and performance. Compare

all components 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 car-

rier 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.
