Inspect the fan section every six months or more

frequently if operating experience dictates. Clean

accumulated dirt and organic matter on the fan interior

surfaces using the following procedure:

1. Disconnect all electrical power to the unit.

2. Wear the appropriate personal protective

equipment (PPE).

3. Use a portable vacuum with HEPA filtration to

remove the loose dirt and organic matter. The filter

should be 99.97% efficient at 0.3 micron particle

size.

4. Thoroughly clean the fan and associated

components with an industrial cleaning solution.

Carefully follow the cleaning solution

manufacturer’s instructions regarding personal

protection and ventilation when using their

product.

5. Rinse the affected surfaces thoroughly with fresh

water and a fresh sponge to prevent potential

corrosion of metal surfaces.

6. Allow the unit to dry completely before putting it

back into service.

7. Properly dispose of all contaminated materials and

cleaning solution.
