Routine Maintenance

See “￿ WARNING Hazardous

Voltage with Capacitors!” on page 49 regarding disconnection of power.

Drain Pans

The condensate drain pan and drain line must be checked to assure the condensate drains as designed. This inspection should occur a minimum of every six months or more often as dictated by operating experience.

If evidence of standing water or condensate overflow exists, identify and remedy the cause immediately. Refer to the “Troubleshooting” section on page 56 for possible causes and solutions.

To clean drain pans:

1Disconnect all electrical power to the unit.

2Wearing the appropriate personal protective equipment, remove any standing water.

3Scrape solid matter off of the drain pan.

4Vacuum the drain pan 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.

5Thoroughly clean all areas with a mild bleach and water solution or an EPA-approved sanitizer specifically designed for HVAC use.

6Immediately rinse the affected surfaces thoroughly with fresh water and a fresh sponge to prevent potential corrosion of metal surfaces.

7Allow the unit to dry completely before putting it back into service.

8Be careful that any contaminated material does not contact other

areas of the unit or building. Properly dispose of all contaminated materials and cleaning solution.

Fans

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 the “Troubleshooting” section on page 56 for possible causes and solutions. To clean the fan section:

1Disconnect all electrical power to the unit.

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

3Vacuum 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.
