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)

Complete the following unit inspections and service
routines at the beginning of each heating season.
• Visually inspect the unit to ensure that the airflow
required for combustion and condenser coil is not
obstructed from the unit.
• Inspect the control panel wiring to verify that all
electrical connections are tight and that the wire
insulation is intact.
