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.
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by
Trane or others, refer to the appropriate
manufacturer’s literature for allowable waiting periods
for discharge of capacitors. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
Clean drain pans using the following procedure:
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.
