Storage

If the fan is stored for any length of time prior to installa-

tion, completely fill the bearings with grease or moisture-

inhibiting oil. Refer to Lubricants on page 6. Also, store the

fan in its original crate and protect it from dust, debris and

the weather.

Outdoor Storage

To maintain good working condition of a TCN when it is

stored outdoors, or on a construction site, follow the addi-

tional steps below.

• Cover the inlet and outlet, and belt tunnel opening to

prevent the accumulation of dirt and moisture in the

housing.

• Periodically rotate the wheel and operate dampers (if

supplied) to keep a coating of grease on all internal

bearing parts.

• Periodically inspect the unit to prevent damaging condi-

tions.

Installation

To prevent damage to the fan during shipping, motors 5

HP and larger, and extremely heavy motors (cast iron or

severe duty) are shipped loose and must be field mounted

by bolting the motor on the motor mounting plate in the

existing mounting slots.

NOTICE! Extreme vibration is a serious problem that

may cause structural and mechanical failure. To help

vibration and noise from being transferred to the build-

ing, isolators are recommended.

Rotating Parts & Electrical Shock Hazard:

Disconnect electric power before working on unit.

Follow proper lockout / tagout procedures to ensure

the unit cannot be energized while being installed or

serviced.

A disconnect switch should be placed near the fan in

order that the power can be swiftly cut off, in case of

an emergency and in order that maintenance

personnel are provided complete control of the power

source.

Grounding is required. All field-installed wiring must

be completed by qualified personnel. All field-

installed wiring must comply with National Electric
