Introduction
The purpose of this manual is to provide instructions that
complement good general practices when installing or operating
fans manufactured by Twin City Fan & Blower. It is the responsibility
of the purchaser to provide qualified personnel experienced in the
installation, operation and maintenance of air moving equipment.
As always, follow good safety practices when installing,
maintaining and operating your air moving equipment. A variety
of safety devices is available. It is the user's responsibility to
determine adequate safety measures and to obtain the required
safety equipment.
Shipping and Receiving

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 carrier
and the necessary damage report filed.
Handling
Handling of all air moving equipment should be conducted by
trained personnel and should be consistent with safe handling
practices. Verify the lift capacity and operating condition of
handling equipment.

Models
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 provided for attaching chains. Lift the
fan in a fashion that protects the fan and fan coating from damage.
Never lift a fan by the inlet or discharge flange, shafting or drives,
impeller, motor or motor base, or in any other manner that may
bend or distort parts.
If fan installation is to be delayed, store the unit in a protected
area. Protect the fan and motor bearings from moisture and
vibration (or shock loading). For extended storage, wrap entire unit
in plastic.
Extended storage requires monthly inspections. Check for
corrosion or damage to the unit and for debris within the fan.
Rotate the fan impeller a few revolutions. Stop the impeller in a
position other than the initial position. Grease the bearings every
month with a grease compatible with the grease supplied with the
bearings.
Foundations and Supporting
Structures
Typical mounting arrangements are shown in Figures 4 and 5 on
page 4. Floor mounted fans should be installed on a flat, level, rigid
concrete foundation. They require the mass of the foundation to be
at least three times that of the fan assembly. The plan area should
be no more than twice that required by the equipment. Foundations
with larger areas should have correspondingly larger mass. Anchor
bolts should be "L" or "T" shaped with sufficient length for nuts,
washers, shims and threads for draw-down. Each bolt should be
placed in a sleeve or pipe with a diameter larger than the bolt to
allow for adjustment. When the mounting surface and the surface
of the fan base do not match, shim or make allowance for grouting.
Do not distort the fan when tightening the anchor bolts.
