To keep the unit operating safely and efficiently, the
manufacturer recommends that a qualified service
technician check the entire system at least once each
year or sooner if needed. The service technician should
examine these areas of the unit:
•
filters (for cleaning or replacement)
•
motors and drive system components
•
safety controls (for mechanical cleaning)
•
electrical components and wiring (for possible
replacement and connection tightness)
•
condensate drain (for proper sealing and cleaning)
•
unit duct connections (to see that they are
physically sound and sealed to the unit casing)
•
unit mounting support (for structural integrity)
•
the unit (for obvious unit deterioration)
