Installation

Most motors are shipped mounted on the fans with belts

and drives installed. However, extremely heavy motors and

drives are shipped separately. These motors and drives will

require field installation. Please refer to pages 3-5.

Foundation

This fan requires a strong, level foundation of reinforced

poured concrete. A correctly designed concrete foundation

provides the best means for mounting floor units. The foun-

dation’s size is determined by fan size, motor size and posi-

tion, and the specific location of the installation.

Use the following guidelines to calculate foundation size:

• The overall dimensions of the foundation should extend

at least 6 inches beyond the outline of the fan and its

motor.

• The weight of the foundation should be 2 to 3 times the

weight of the unit and its motor.

Isolation

Isolation Base

To prevent vibration and noise from being transferred to

the building isolators are recommended. Arrangement 1

fans require an isolation base to effectively isolate the fan

system: fan, base, motor, drive, guards, etc. Bases must

have sufficient rigidity to resist belt pull and prevent drive

distortion which can lead to excessive belt and bearing

WARNING

This unit has rotating parts. Safety precautions

should be exercised at all times during installation,

operation, and maintenance.

ALWAYS disconnect power prior to working on fan.

Receiving and Inspection

Carefully inspect the fan and accessories for any dam-

age and shortage immediately upon receipt of the fan.

• Turn the wheel by hand to ensure it turns freely and

does not bind.

• Inspect dampers (if supplied) for free operation of all

moving parts.

• Record on the Delivery Receipt any visible sign of

damage.

Handling

Lift the fan by the base or lifting eyes. Never lift by the

shaft, motor, or housing.

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 the fan when it is

stored outdoors, follow the additional instructions below.

• Coat the shaft with grease or a rust preventative com-

pound.

• Wrap bearings for weather protection

• Cover the inlet and outlet of the fan to prevent the accu-

mulation of dirt and moisture in the housing.

• Periodically rotate the wheel and operate dampers (if

supplied).

• Periodically inspect the unit to prevent damaging condi-

tions.
