materials, gasses or fumes are present, unless it has specifically designed and manufactured for use in that
environment. Explosion or Fire could result!

5. This ventilator is designed to be mounted in a wall or other building opening.

6. A damper, if used, should be securely mounted within the ductwork or opening in a manner which allows free and

unobstructed operation. Allow a minimum of 8” of clearance from between the fan and damper.

12. WARNING! Before starting the fan, turn the propeller to assure it rotates freely. If needed, adjust the

propeller/shaft/bearing/motor position as required to achieve necessary clearances.

13. WARNING! Check all set screws and keys. Tighten as necessary prior to fan startup.

14. Anchor the fan securely to the opening. Use a minimum of four lag bolts or other suitable fasteners.

MAINTENANCE

1. DANGER! Before performing any maintenance on the fan, be sure power is turned off and locked in the OFF

position at the service entrance before servicing the fan.

2. Ventilators should be carefully checked at least once a year. For critical or rugged applications, a routine check
every two or three months is suggested.

3. All motors supplied with CARNES ventilators carry a one year warranty from date of shipment. For repairs within
the warranty period, the motor must be taken to the motor manufacturer’s authorized service dealer. Contact your

CARNES representative for additional warranty details.

4. A periodic motor check should consist of spinning the motor shaft with the power off to be sure the motor turns
freely.

5. The propeller should not require maintenance except for removing foreign materials that may accumulate on the

blades. The balance weights should not be disturbed. If a propeller has to be removed from the shaft, do not apply
force that will damage the bearing or warp the propeller. Use a wheel puller.
