CARE AND MAINTENANCE
For continued high performance, and to minimize possible equipment failure, it is essential that periodic maintenance be performed on this
equipment.
PROCEDURE 1—BEFORE YOU REQUEST A SERVICE CALL
Check the indoor and outdoor disconnect switches. Verify that circuit breakers are in ON position and 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 setting of your indoor thermostat. If you desire cooling, see that the temperature control selector is set below room temperature and the
SYSTEM switch is on the COOL or AUTO position.
If your comfort system still fails to operate, contact your servicing dealer for troubleshooting and repairs. Specify your apparent problem, and state
the models and serial numbers of your equipment. (You should record them on your warranty.) With this information your dealer may be able to
offer helpful suggestions over the telephone or save valuable time through knowledgeable preparation for the service call.
PROCEDURE 2—REGULAR DEALER MAINTENANCE
In addition to the routine maintenance you perform, your home comfort system should be inspected regularly by a properly trained service
technician. The inspection (preferably twice each year, but at least once every 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 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.
Your servicing dealer may offer an economical service contract that covers seasonal inspections. Ask for further details.
FOR THE RECORD
Record the models and serial numbers of your new equipment in the spaces provided on your warranty. This information is necessary should you
ever require information or service.
