(HEPA) filters with a minimum efficiency of 99.97 percent at 0.3 micron particle size.

5. Thoroughly clean any contaminated area(s) with a mild bleach and water solution or an EPA-

approved sanitizer specifically designed for HVAC use.

6. Immediately rinse the affected surfaces thoroughly with fresh water and a fresh sponge to

prevent potential corrosion of metal surfaces.

Inspecting and Cleaning Fans

Fan sections of air handlers should be inspected every six months at a minimum or more frequently

if operating experience dictates. If evidence of microbial growth (mold) is found, identify and

remedy the cause immediately. Refer to “Troubleshooting” on page 98 for possible causes and

solutions. To clean the fan section:

1. Disconnect all electrical power to the unit.

2. Wearing the appropriate personal protective equipment, remove any contamination.

3. Vacuum the section with a vacuum device that uses high-efficiency particulate arrestance

(HEPA) filters with a minimum efficiency of 99.97 percent at 0.3 micron particle size.

4. Thoroughly clean any contaminated area(s) with a mild bleach and water solution or an EPA-

approved sanitizer specifically designed for HVAC use.
