The purpose of this manual is to aid in the proper installation and operation of the fans.

These instructions are intended to supplement good general practices and are not intended to

cover detailed instruction procedures. It is the responsibility of the purchaser to assure that the

installation and maintenance of this equipment is handled by qualified personnel.

Inspect all shipments carefully for damage. THE RECEIVER MUST NOTE ANY

DAMAGE ON THE CARRIER’S BILL OF LADING AND FILE A CLAIM

IMMEDIATELY WITH THE FREIGHT COMPANY.

INSTALLATION

1. The fans, when lifted, should be lifted using the flanged ends of the tube or by placing a

sling around the fan tube, and never by the motor, belt tube or motor base.

2. Caution: The fan contains rotating parts and requires electrical service. Appropriate

safety precautions should be taken during installation, operation and maintenance.

3. All electrical work must be done, in accordance with all applicable electrical codes, by a

qualified electrician.

4. Prior to wiring, ensure that the power supply is locked in the OFF position and that the

motor nameplate voltage and the supply voltage match.

5. Be sure to keep all electrical wiring clear of any moving parts.

6. Tighten all nuts, bolts and setscrews to the proper torque settings (see chart), as some

may have loosened during shipping.

7. Before starting the fan, ensure that the wheel rotates freely.

8. On belt driven fans, assure that the belts are aligned and tensioned correctly.

9. Assure that all protective guards and other safety devices are installed properly prior to

fan start-up.

10. When hanging tube axial fans, the installer must provide suitable rods and hanging vibration isolators (both vertical and horizontal applications). Do not support the ductwork, etc., from the fan. The fan should be supported independently using isolators designed to support the weight of the fan only. 11.

Suspended Fans This is the most common method of installation. Fans mounted in ductwork are usually are suspended from the ceiling using threaded rod and either spring or rubber in shear ceiling isolators. • Attach threaded rod to the support structure directly over the fan mounting holes. • Raise the fan up to the installation location and temporarily support it in place.

Start Up Restore power to the fan, turn it on and check for the following. • Correct rotation • Improper amperage • Excess vibration • Unusual noise • Incorrect belt tension or alignment If a problem is discovered shut off the fan and refer to the section on troubleshooting to discover the cause of the problem. The fan should be inspected after 30 minutes, 8 hours and 24 hours of operation to ensure all fasteners are tight and belts are properly tensioned and aligned.

7. The standard pillow blocks on belt driven fans are factory lubricated. These bearings should be lubricated on a semi- annual basis (more frequently in severe applications) using a high quality lithium based grease. With the unit running add grease very slowly, using a manual grease gun, until a slight bead of grease forms at the seal. Be careful not to unseat the seal by over lubricating or by using excessive pressure.

Rotate the shaft to find the center of free movement. Install the propeller adjusting the bearing location to center the blade in the venturi. • Tighten the bearing bolts to the proper torque rating (see chart) • Turn the propeller by hand the propeller should rotate freely with the same resistance as before the bearing bolts were tightened. • Tighten all setscrews to the proper torque rating (see chart) • Install pulley and adjust belt tension.
