WARNING!!
Disconnect power before installing or servicing fan. High voltage electrical input is needed for this equipment. This work should be performed by a qualified electrician.

Electrical

Before connecting power to the heater, read and understand this entire section of this document. As-built wiring diagrams are furnished with each fan by the factory, and are attached to the door of the unit.

Electrical wiring and connections should be done in accordance with local ordnances and the National Electric Code, ANSI/NFPA70. Be sure the voltage and phase of the power supply and the wire amperage capacity is in accordance with the

motor nameplate. For additional safety information refer to AMCA publication 410-96, Recommended Safety Practices for Users and Installers of Industrial and Commercial Fans.

1.Always disconnect power before working on or near a

heater. Lock and tag the disconnect switch or breaker to prevent accidental power up.

2.An electrical drop containing the motor power wiring is shipped with every fan. The electrical drop should be brought through one of the conduit openings located in the base of the unit, run through the curb, and connected to a junction box inside the building.

3.A dedicated branch circuit should supply the motor circuit

with short circuit protection according to the National

Electric Code. This dedicated branch should be run to the junction box mentioned above and connected as shown in a following

illustration labeled “Fan to Building Wiring Connection”.

4. Make certain that the power source

is compatible with the requirements of your equipment.

The heater nameplate identifies the proper phase and voltage of the motor.

5. Units shipped with an optional

remote panel have two electrical circuit drops. It is important to run

the motor wires in a separate conduit from the remote control wiring. The DC wires from the unit temperature controller, located in the control drop, should either be shielded cable or be run in a separate conduit.

6.Before connecting heater to the building power source, verify power line wiring is de-energized.

7.Secure the power cables to prevent contact with sharp objects.

8.Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces or chemicals.

9.Before powering up the heater, check fan wheel for free rotation and make sure that the interior of the heater is free of loose debris or shipping materials.

10.If any of the original wire supplied with the heater must be replaced, it must be replaced with type TW wire or equivalent.

Motorized Intake Damper

On units shipped with the optional motorized intake damper, a power transformer is supplied with the unit if the main incoming voltage is greater than 120V. The damper motor is automatically energized when the main disconnect switch is in the ON position. No external wiring to the damper motor is required.
