Receiving and Inspection

Immediately upon receipt of an AC fan,

carefully inspect the fan and accessories for

damage and shortage.

• Turn the wheel by hand to ensure it

turns freely and does not bind.

• Record on the Delivery Receipt any visi-

ble sign of damage.

Handling

Lift the fan by the shipping carton or lifting lugs provided

under top cap. NOTICE! Never lift by the shaft, motor or

housing.

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

Code (NFPA 70) and all applicable local codes.

Failure to follow these instructions could result in

death or serious injury.

Storage

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

lation, store it in its original shipping crate and protect it

from dust, debris and the weather.

Damper

Use of any backdraft dampers is NOT permitted. Fire

dampers and/or smoke dampers may be required in a

smoke control system. These dampers must meet the

requirements determined by the local code authority.

Installation

If the fan was delivered with the motor unmounted, see

the maintenance section for belt and pulley installation.

Wiring

NOTICE! All wiring should be in accordance

with local ordinances and the National

Electrical Code, NFPA 70. Ensure the power

supply (voltage, frequency, and current

carrying capacity of wires) is in accordance

with the motor nameplate.

(See nextpage for diagram)

The attachment of roof mounted fans to the roof

curb as well as the attachment of roof curbs to the

building structure must exceed the structural

requirements based on the environmental loading

derived from the applicable building code for the

site. The local code official may require variations

from the recognized code based on local data. The

licensed engineer of record will be responsible for

prescribing the correct attachment based on

construction materials, code requirements and

environmental effects specific to the installation.

Failure to follow these instructions could result in

death or serious injury.
