Keep your outdoor unit
looking new for years.
Clean the enamel finish of your outdoor
unit with soap and water. for stubborn
grease spots, use a household deter-
gent. do not use lacquer thinner or other
synthetic solvents as they may damage
the finish.
Call your dealer for additional
routine maintenance.
your outdoor unit should be inspected
regularly by a properly trained service
technician. The inspection (preferably
twice each year, but at least once a
year) should include the following:
• Routine inspection of air filter(s). Re-
placement or cleaning as required.
• Inspection and cleaning of the blower
wheel, housing, and motor as required.
Setting the temperature.
Place the system switch on Cool, and
the fan switch on aUTo. Then set the
temperature by using the indicator on
the thermostat* control.
now your system will cool your house
whenever the indoor temperature climbs
above the thermostat setting.
it will shut off when the desired room
temperature is reached.
in winter, it works the same way. When
the system switch is on heaT, the
system will operate whenever the room
temperature falls below the temperature
setting. once the desired temperature is
reached, the system will shut off.
Save energy with a
programmable thermostat.*
Program the thermostat for the tem-
peratures that meet your comfort level.
The Trane programmable thermostat
has up to four setup or setback periods
each day, plus weekend and vacation
programs.
* accessory, purchased separately. Carefully read
the accompanying thermostat manual for complete
operating instructions.

Condensate drains should be checked and cleaned
periodically to assure condensate can drain freely
from coil to drain. if condensate cannot drain freely,
water damage could occur.
• Inspection and, if required, cleaning of
indoor and outdoor coils.
• Inspection of the indoor coil drain pan,
plus the primary and secondary drain
lines. if supplied, the auxiliary drain pan
and line should be inspected at this
time. service should include cleaning,
if required.
• A check of all electrical wiring and con-
nections.
• A check for secure physical connections
of individual components within units.
How to operate your system
for peak performance
Let the thermostat do its job.
your system will perform most efficiently
when you let the thermostat control it.
Turning the system on and off manually
is usually much less efficient. so let the
thermostat do its job.
We recommend keeping the tempera-
ture setting at 78°f for cooling, 68°f for
heat ing. however, you can select the
temperature that meets your comfort
level.
The point is, once you've set the ther-
mostat, keep subsequent adjustments to
a minimum.
When you're going to be away from
home for a few days, or when outdoor
temperatures are moderate, don't let the
outdoor unit run unnecessarily. lower
the thermostat to 55°f in the winter. and
raise it to 85°f in summer. Then when
you return, or when temperature condi-
tions dictate, you can reset the system
and it will resume making your home
comfortable again.
How to help reduce summer humidity.
in summer, your outdoor unit does more
than cool the air — it helps remove
the excess moisture that can make the
inside of your home feel muggy.

improper installation, adjustment, alteration,
service, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which
may cause personal injury or property damage.
Consult a qualified installer or service agency for
information or assistance. The qualified installer
or agency must use factory-authorized kits or
accessories when modifying this product.
• Operational check of the outdoor unit
to determine actual working condition.
necessary repair and/or adjustment
should be performed at this time.
• Your servicing dealer may offer an
economical service or preventative
maintenance agreement that covers
seasonal inspections. Ask your
dealer for further details.

!
if heating system is not operational during the cold
weather months, provisions must be taken to
prevent freeze-up of all water pipes and water
receptacles. This is very important during times
of vacancy.
When removing this moisture your sys-
tem must work harder than when simply
cooling the air.
That's why kitchens, bathrooms and
utility rooms should have vents and ex-
haust fans. These devices help prevent
accumulation of moisture throughout the
rest of the house so your outdoor unit
works less to keep you comfortable.
Many homeowners have found that op-
erating their system in continuous fan
mode (thermostat in the "on" position)
offers benefits such as elimination of hot
and cold spots in the home and constant
air filtration. however, continuous fan
mode during cooling operation may not
be appropriate in humid climates. if the
indoor air exceeds 60% relative humidity
or simply feels uncomfortably humid, it is
recommended that the fan only be used
in the aUTo mode.
