INSTRUCTION MANUAL FOR STANDARD EXHAUST FANS
Read Instructions complete before Installation & save for reference
Congratulations on the purchase of your quality built direct drive, wall exhaust ventilation fan. All of these models use totally enclosed motors with thermal over load  protection. Variable speed motors are high efficiency motors which save on electrical costs and can be run as a single speed motor. The motors are mounted on heavy gauge  welded steel rod motor mounts that have a Bright Zinc finish. Fans come fully assembled and 100% of fans are tested for proper operation before shipping.
These are general  Instructions which cover our singled, variable and two sped standard fans, as well as our singled sped explosion’s Proof models.

STANDARD FANS:
These models have a rugged, welded steel box housing with a powder coated finish and aluminum or plastic exhaust louvers that are supported by long life nylon bushings. The louvers open automatically when the fan starts up and close when the fan stops

EXPLOSION PROOF FANS:

Explosion proof fans are equipped with single speed explosion proof motors and aluminum blades so sparks cannot occur if a metal object obstructs the blade path.  Explosion proof fans have the same quality welded steel box housing and heavy gauge welded guard as the standard fans. These fans should be used to ventilate hazardous  areas. Locations are considered hazardous if the atmosphere contains or may contain gas, vapor, or dust in explosive quantities.
The motor ambient temperature Is not to exceed +40˚c or -25˚c unless the motor nameplate specifically Permits  another value. the following table Indicate which hazardous classifications canard explosion’s Proof fans do and do not meet.

These fans are supplied with single, two or variable speed motors. Single and two speed motors are 120V only. Variable speed motors are dual voltage. All dual voltage motors  are pre-wired at 240V in our factory. Rewire motor as per motor nameplate if running fan at 120V. Please see the motor nameplate for wiring diagram. Make  electrical connections in motor connection box as per the motor nameplate. Two speed fans require a two speed control or 3 position toggle switch to change from high/ low/off.
