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. Cut and frame the appropriate wall opening. Fans mounted to a wall require a

different wall opening than fans mounted in cabinets or sleeves. For specific

dimensions, refer to the submittal drawing for the specific fan configuration.

2. Mount the fan in the opening with the fan panel directly over the load bearing

support and if this is not practical angle supports must be provided to transfer

the fan weight to the load bearing structure.

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

Appropriate safety precautions should be taken during installation, operation

and maintenance.

4. Warning: Do not install or operate this fan in an environment where

combustible materials, gasses or fumes are present unless it was specifically

designed and manufactured for that application.

5. A damper, if used, should be securely mounted in a manner that allows free and

unobstructed operation.

6. All electrical work must be done, in accordance with all applicable electrical

codes, by a qualified electrician.

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

the motor nameplate voltage and the supply voltage match.

8. Be sure to keep all wiring clear of any rotating parts. 9. Before starting the fan ensure that the wheel rotates freely. 10. Tighten all nuts; bolts and setscrews prior to fan start up. 11. On belt driven fans make sure that the belts are tensioned and aligned correctly. 12. Ensure that all protective guards and other safety devices are installed properly prior to fan start up. Wiring Instructions A qualified electrician in accordance with all local and National Electrical Codes should do all wiring.

Typical Installation Refer to page 8 Start Up Turn the fan on and inspect for the following. • Direction of rotation • Improper motor amperage • Excessive Vibration • Unusual Noise • Improper 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.

• 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.

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. You should go through the start up steps as outlined above.

TYPICAL INSTALLATIONS Wall exhaust fan with cabinet, back guard and shutter The above drawing illustrates the typical installation of an exhaust fan with cabinet, back guard and shutter in a masonry wall. The installer shall provide angle iron framing and suitable fasteners (hex bolts or lag screws) to support the fan. The cabinet and framing should be caulked to the exterior wall. Fans with motors in excess of 50 pounds should also be supported using hanging rods or by supports placed underneath the fan.
