Lubrication

Clean Fan
Motor: Remove any dust accumulation from motor using a brush or cloth (DO NOT USE A PRESSURE WASHER ON
THE MOTOR). A clean motor will run cooler and last longer. Check if the motor is secure in its mount.
Shutter: Carefully clean dust from shutter vanes and frame so that shutter opens and closes freely. If shutters are
extremely dirty, you can lose up to 20% of your fan capacity.
Guard: Clean any dust or dirt buildup from fan guards using a brush. Dirty guards can also reduce airflow.
Housing
Remove dust and dirt accumulations from housing with a pressure washer.
Do not wash or spray motor directly.
If any portion of the fan is cleaned with a power washer or any liquid it is highly recommended to run the fan for
a minimum of 15 minutes to allow the fan and motor to dry before it is left idle for any length of time.
