INDUSTRIAL PLUG FANS

This Manual is for the following Fans: D/44 Plug Fans; D/70 Plug Fans.

TO ORDER SPARE PARTS:

D/70 Plug Fan

Spare or repair parts may be ordered from your nearest

Chicago Sales Engineer by giving the part name,

(Wheel, Motor, Bearing, etc.) and the FAN SERIAL

NUMBER taken from the nameplate or the JOB ORDER

drawings. If possible also give the bearing or shaft

size and the fan class. Due to the small number of

parts required, spare parts lists are neither necessary nor

available. Use these instructions instead.

RECEIVING:

Chicago Blower Corporation equipment is prepared for shipment in

accordance with the Uniform Freight Classification. It is thoroughly

inspected at the factory and, barring damage in transit, should be in good

condition upon arrival.

When a carrier signs Chicago Blower Corporation’s bill of lading, the

carrier accepts the responsibility

for any subsequent shortages or

damage evident or concealed, and

any claim must be made against

the carrier by the purchaser.

Evident shortage or

damage should be

noted on the carrier’s delivery document

before signature of accep-

tance. Inspection by the carrier of damage evident or concealed must be

requested. After inspection, issue a purchase order for necessary parts

or arrange for return of the equipment to Chicago Blower Corporation

factory for repair.

Chicago Blower fans are shipped, skidded, and may be handled and

moved using good rigging techniques, being careful to avoid concentrated

stresses that distort any of the parts.

STORAGE:

If the fan installation is to be delayed, store the unit in a dry, protected

area. Protect the fan, especially fan and motor bearings, from moisture

and vibration. Protect all machined surfaces such as shafts, couplings,

and bushings. Rotate the wheel several revolutions every two weeks,

stopping the wheel in a position other than its initial position. Keep the

bearings fully greased by filling monthly with a grease compatible to that

originally supplied. Contact Chicago Blower for extended storage

instructions.

SAFETY PRECAUTIONS:

The fan which you have purchased is a rotating piece of equipment and

can become a source of danger to life or cause injury if not properly

applied. The

maximum operating temperature

or

speed

for which this

fan is designed

must not be exceeded

. These limits are given in our

catalog or on Chicago Blower Corporation drawings.

Personnel who will operate this fan, or those who will perform mainte-

nance thereon,

must be given this bulletin to read and warned of the

potential hazards of this equipment.

This pamphlet contains general recommendations, but specific require-

ments may apply to the individual installation. Such requirements are

outlined in federal, state and local safety codes. Strict compliance with

these codes, and strict adherence to these installation instructions are

the responsibility of the user.

INSTALLATION:

1. Inspect the equipment for correctness and condition. If any discrepancies

are found, contact your local Chicago Blower Corporation Engineer

immediately for assistance.

2. The fan wheel assembly has been dynamically balanced for vibration-

free operation. Any damage or rough handling may destroy this bal-

ance and require rebalancing. Take care to prevent damage to the

wheel hub finished bore. Protect the fan shaft from mars, gouges,

nicks or bending.

3. The fan bearings have been factory lubricated and are shipped in

cartons to protect them. Do not remove the bearings from the cartons

until ready for assembly.
