(1) SS Damper Door Striker Plates from Bag 9 (Misc. Hardware)
at each location, angle the striker plate so the angle matches the fan
housing. To secure the striker plates, press the rubber gasket back down.
NOTE: No hardware is used to secure striker plates at this time.
11

cone assembly and not underneath it or crushed anywhere.
• Using the included #3 Phillips Bit from Bag 1 (Tools) and (1) #14-
10 x 2” Screw from Bag 5 (Part 1) at each of the venturi section
connections, secure the cone assembly to the housing
• Recheck the rubber gasket for proper placement and make adjustments
as needed
NOTE: Select one of the cone section that is across from the eyebolts
installed in Step 4, do not secure that section to the
housing. (For further clarity preview the next couple of steps)
• Secure 7 of the 8 cone sections to the housing using the included #3

Maintenance Instructions:
• Disconnect power before cleaning or maintaining your fan in order
to prevent serious injury or death.
• Service and repair of fan should only be completed by a qualified
technician.
• For maximum efficiency and fan life, keep the following free from
dirt and dust: blades, damper doors, motor and guard.
• The totally enclosed air over motor has sealed ball bearings and
does not require additional oil.
General Wiring Instructions:
• Wiring should only be performed by a trained electrician to prevent
injury or death.
• Install manual disconnect switch inside building adjacent to fan.
• Route wire to motor with drip loop and secure. Drip loop will drain
accumulated moisture away from the motor.
• Configure internal wires to match supply voltage and wire accord-
ing to motor nameplate. Test to verify correct rotation.
• Only permit power to unit when guards are properly installed to
prevent injury.
