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 conden-
sate 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.

ƽWARNING
Hazardous Voltage w/Capaci-
tors!
Disconnect all electric power, including
remote disconnects before servicing.
Follow proper lockout/tagout proce-
dures 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 an
appropriate voltmeter that all capacitors
have discharged. Failure to disconnect
power and discharge capacitors before
servicing could result in death or serious
injury.
Note: For additional information regard-
ing the safe discharge of capacitors, see
PROD-SVB06A-EN or PROD-SVB06A-FR.
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.
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.
Inspecting and Cleaning the
Fan
Inspect the fan section every six months
or more frequently if operating
experience dictates. Clean accumulated
dirt and organic matter on the fan interior
surfaces following the procedure below:
1. Disconnect all electrical power to the
unit.
2. Wear the appropriate personal
protective equipment (PPE).
3. Use a portable vacuum with HEPA
filtration to remove the loose dirt and
organic matter. The filter should be
99.97% efficient at 0.3 micron particle
size.
4. Thoroughly clean the fan and
associated components with an
industrial cleaning solution. Carefully
follow the cleaning solution
manufacturer’s instructions regarding
personal protection and ventilation
when using their product.
5. Rinse the affected surfaces thoroughly
with fresh water and a fresh sponge to
prevent potential corrosion of metal
surfaces.
6. Allow the unit to dry completely before
putting it back into service.
7. Properly dispose of all contaminated
materials and cleaning solution.
