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 trouble shooting section of this
manual for possible causes and solutions.
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
mat
ter. 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
bleac
h and water solution or an EPA-approved sanitizer

WARNING
Hazardous Voltage w/Capacitors!
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 byTrane or
others, refer to the appropriate manufacturer’s literature
for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged. Failure to disconnect power
and discharge capacitors before servicing could result in
death or serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
