Maintenance - Trane TTA240F Series Installation Operation & Maintenance

Maintenance

Perform all of the indicated
maintenance procedures at the
intervals scheduled. This will prolong
the life of the unit and reduce the
possibility of costly equipment failure.
Monthly
Conduct the following maintenance
inspections once per month.
! 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.
1. Inspect air filters and clean if
necessary.
2. Check unit wiring to ensure all
connections are tight and that the
wiring insulation is intact.
3. Check drain pans and condensate
piping to insure they are free of
obstacles.
4. Manually rotate the indoor fan to
insure proper operation.
5. Inspect the evaporator and
condenser coils for dirt and
debris. If the coils appear dirty,
clean them.
6. With the unit operating in the
cooling mode, check the suction
and discharge pressures and
compare them with Pressure
Curve values in unit Service Facts.
Record these readings on the
"Maintenance Log. "

7. Observe indoor fan operation and
correct any unusual or excessive
vibration. Clean blower wheels as
needed.
Annually (Cooling Season)
The following maintenance
procedures must be performed at the
beginning of each cooling season to
insure efficient unit operation.
1. Perform all of the monthly
maintenance inspections.
2. With the unit operating, check
unit superheat and record the
reading in the "Maintenance
Log. "
3. Remove any accumulation of dust
and/or dirt from the unit casing.
4. Remove corrosion from any
surface and repaint. Check the
gasket around the control panel
door to insure it fits correctly and
is in good condition to prevent
water leakage.
5. Inspect the evaporator fan belt. If
it is worn or frayed, replace it.
6. Inspect the control panel wiring to
insure that all connections are
tight and that the insulation is
intact.
Lubricate the indoor fan motor
bearing with a non detergent 20-
weight oil. (To insure good bearing
lubrication, condenser fan motor
bearings should be lubricated once
every six months.)
Note: Some motors are permanently
lubricated.
7. Check refrigerant piping and
fittings for leaks.
The following warning complies with
State of California law, Proposition 65.
! WARNING
Fiberglass Wool!
Product contains fiberglass wool.
Disturbing the insulation in this
product during installation,
maintenance or repair will expose you
to airborne particles of glass wool
fibers and ceramic fibers known to
the state of California to cause cancer
through inhalation. Glass wool fibers
may also cause respiratory, skin or
eye irritation.
Precautionary Measures
• Avoid breathing fiberglass dust.
• Use a NIOSH approved dust/mist
respirator.
• Avoid contact with the skin or
eyes. Wear long-sleeved, loose-
fitting clothing, gloves, and eye
protection.
• Wash clothes separately from
other clothing: rinse washer
thoroughly.
• Operations such as sawing,
blowing, tear-out, and spraying
may generate fiber
concentrations requiring
additional respiratory protection.
Use the appropriate
approved respirator in these
situations.
First Aid Measures
Eye Contact - Flush eyes with water
to remove dust. If symptoms
persist, seek medical attention.
Skin Contact - Wash affected areas
gently with soap and warm water
after handling.
