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 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
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
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
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

back on. Failure to follow this procedure
could result in damage to your system.
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
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
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.
