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 detergent.
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).
Replacement or cleaning as required.
• Inspection and cleaning of the blower
wheel, housing, and motor as required.
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
connections.
• A check for secure physical connections
of individual components within units.
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.
How to operate your system
for peak performance
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.
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 temperature
setting at 78°F for cooling, 68°F for heat-
ing. However, you can select the tem-
perature that meets your comfort level.
The point is, once you've set the
thermostat, keep subsequent adjust-
ments 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. When remov-
ing this moisture your system 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.
