Keep your air conditioner looking

other synthetic solvents as they may
damage the finish.

least once a year) should include

How to operate your system
for peak performance
How to help reduce summer humidity.
In summer, your air conditioner 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
exhaust fans. These devices help
prevent accumulation of moisture
throughout the rest of the house so
your air conditioner works less to keep
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
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
Program the thermostat for the temp-
eratures that meet your comfort level.
The Trane electronic programmable
thermostat has up to four setup or
setback periods each day, plus week-
end 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 temper-
ature setting at 78°F for cooling, 68°F
for heating. However, you can select
the temperature that meets your
The point is, once you’ve set the
thermostat, 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 tempera-
ture conditions 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.

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.
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
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.
