equipment in the spaces provided. This information, along with

you ever require information or service.
BEFORE YOU REQUEST A SERVICE CALL
BEFORE YOU CALL FOR SERVICE, CHECK FOR
THESE EASILY SOLVED PROBLEMS:
• Check the indoor and outdoor disconnect switches. Verify that
circuit breakers are on or that fuses have not blown.
• Check for sufficient airflow. Check the air filter(s) for any
accumulations of dirt. Check for blocked return-air or supply-
air grilles. Be sure grilles are open and unobstructed.
• Check the settings on your indoor thermostat. If you desire
cooling, see that the temperature set point is set below room tem-
perature and the MODE is set to COOL or AUTO. If you require
heat, be sure the desired temperature set point is set above room
temperature and the MODE is HEAT or AUTO. The FAN
should be set to ON for continuous blower operation or AUTO
if you wish blower to function only while the unit is operating.
• Check note concerning special features and time delays in
“Operating Your Air Conditioner” section.
If your comfort system still fails to operate, contact your servic-
ing dealer for troubleshooting and repairs. Specify your apparent
problem, and state the model and serial numbers of your equip-
ment. (You should have them recorded on page 6 of this book-
let.) With this information, your dealer may be able to offer
helpful suggestions over the phone or save valuable time through
knowledgeable preparation for the service call.
REGULAR DEALER MAINTENANCE
In addition to the routine mainte-
nance that you perform, your
home comfort system should be
inspected regularly by a properly
trained service technician. The
inspection (preferably each year,
but at least every other year)
should include the following:
• Routine inspection of air filter(s). Replacement or cleaning as
required.
