WARNING
Live Electrical Components!
During installation, testing, servicing,
and troubleshooting this equipment, it
may be necessary to work with live
electrical components. Have a
qualified licensed electrician or other
individual who is properly trained in
handling live electrical components
perform these tasks. Failure to follow
all electrical components could result
in death or serious injury.
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 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.

Monthly Maintenance
1. Inspect unit air filters. Clean or replace
if airflow is blocked or if filters are dirty.
2. Check the main and auxiliary drain
pans on fan-coil units to be
sure the pans are clean and do not
impede the condensate flow
through the drain line.
Annual Maintenance
Check and tighten all set screws, bolts,
locking collars and sheaves.
1. Inspect the unit cabinetry for chips or
corrosion. Clean or repair to
provide unit protection.
2. Inspect the fan wheel and housing for
damage. Rotate the fan
wheel manually to be sure movement
is not blocked by obstructions.
3. Inspect the coil fins for excessive dirt or
damage. Remove dirt and
straighten fins.
4. Clean and tighten all electrical
connections.
5. Inspect the strainer option for debris
trapped in the filter screen.
