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:

Disconnect all electrical power to 
the unit.

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

Scrape solid matter off of the 
drain pan.

Vacuum 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.

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

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

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

Be careful that any contaminated 
material does not contact other 

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

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:

Disconnect all electrical power to 
the unit.

Wearing the appropriate 
personal protective equipment, 
remove any contamination.

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.

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

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

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

Be careful that any contaminated 
material does not contact other 
areas of the unit or building. 
Properly dispose of all 
contaminated materials and 
cleaning solution.

Align bearing set screws as 
illustrated in Figure 49. Table 4 on 
page 47 provides bearing set screw 
torque measurements.
