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.

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. - Page 4 • 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.
