Inspecting and Cleaning the
Drain Pan
Check the condensate drain pan and drain line to
ensure that the condensate drains properly at least
every six months or as dictated by operating
experience.
If evidence of standing water or condensate overflow
exists, take steps to identify and remedy the cause
immediately. Refer to the troubleshooting section of
this manual for possible causes and solutions.

1. Disconnect all electrical power to the unit.
2. Don the appropriate personal protective equipment
(PPE).
3. Remove all standing water.
4. Use a scraper or other tools to remove and solid
matter. Remove solid matter with a vacuum device
that utilizes high efficiency particulate arrestance
(HEPA) filters with a minimum efficiency of 99.97%
at 0.3 micron particle size.
5. Thoroughly clean the contaminated area(s) with a
mild bleach and water solution or an EPA-approved
sanitizer specifically designed for HVAC use.
Carefully follow the sanitizer manufacturer’s
instructions regarding product use.
6. Immediately rinse the drain pan thoroughly with
fresh water to prevent potential corrosion from the
cleaning solution.
7. Allow the unit to dry thoroughly before putting the
system back into service.
8. Properly dispose of all contaminated materials and
cleaning solution.
