How to operate your system
for peak performance
How to help reduce summer humidity.
In summer, your heat pump does more
than cool the air — it helps remove the
excess moisture, that can make the
inside of your home feel muggy. When
removing 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 air conditioner
works less to keep you comfortable.
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 an electronic
programmable thermostat.*
Program the thermostat for the tempera-
tures that meet your comfort level. The
Trane electronic programmable thermo-
stat 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 thermo-
stat, 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
air conditioner 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.
Never stop the system by shutting off
the main power.
If the main power is ever disconnected
for more than three hours, turn off the
thermostat. Then wait for at least three
more hours after the power has been
restored before turning the thermostat
back on. Failure to follow this procedure
could result in damage to your system.

accompanying thermostat manual for complete
operating instructions.

CAUTION
!
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.
▲
CAUTION
!
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.

WARNING
!
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.
Making sure your outdoor unit is kept
clear at all times helps it work at peak
efficiency.
Keep your heat pump looking
new for years.
Clean the enamel finish of your heat
pump 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 heat pump system 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.
• 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.
• Operational check for the heat pump
system 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.
