5. Setup and Installation

This section outlines the general steps for replacing an existing exhaust fan motor and blower. Specific installation procedures may vary slightly depending on your existing fan housing. Always refer to the original fan's manual for detailed housing removal instructions if available.

Required Tools (Not Included):

• Screwdriver (Phillips or flathead, as needed)
• Pliers
• Wire strippers (if new wiring connections are required)
• Voltage tester

Installation Steps:

1. Disconnect Power: Locate the circuit breaker for the exhaust fan and turn off the power. Verify power is off using a voltage tester.
2. Remove Fan Cover: Carefully remove the existing fan's grille or cover. This usually involves pulling down on spring clips or unscrewing fasteners.
3. Remove Old Motor/Blower: Disconnect the power cord from the old motor. Note how the old motor and blower assembly is mounted within the fan housing (e.g., screws, clips). Remove the old assembly.
4. Install New Motor/Blower: Position the TTAMG S86325000 assembly into the fan housing. Secure it using the existing mounting points (screws or clips). Ensure the blower wheel spins freely without obstruction.
5. Connect Wiring: Connect the power cord of the new motor to the fan's electrical supply. Ensure connections are tight and secure. If the new motor has a plug, simply plug it into the receptacle within the fan housing.
6. Replace Fan Cover: Reattach the fan grille or cover.
7. Restore Power: Turn the power back on at the circuit breaker. Test the fan's operation.

6. Operation

Once properly installed, the TTAMG S86325000 exhaust fan motor and blower operates by drawing air from the room and expelling it, helping to reduce humidity, odors, and airborne pollutants. The fan is typically activated by a wall switch connected to the fan's electrical circuit.

• Turn on the wall switch to activate the fan.
• Turn off the wall switch to deactivate the fan.

For optimal performance, operate the fan during and after activities that generate moisture or odors, such as showering or cooking.

Cleaning the Blower Wheel and Housing:

1. Disconnect Power: Turn off power to the fan at the circuit breaker.
2. Remove Fan Cover: Remove the fan grille/cover.
3. Access Blower Wheel: Carefully detach the motor and blower assembly from the housing.
4. Clean Components: Use a soft brush, cloth, or vacuum cleaner to remove dust and debris from the blower wheel blades and the interior of the fan housing. Avoid using harsh chemicals or abrasive cleaners.
5. Reassemble: Reattach the motor and blower assembly, then replace the fan cover.
6. Restore Power: Turn power back on at the circuit breaker.
