All service should be performed by a
qualified service technician. Before
removing access panels or control
covers to expose moving parts or non-

disconnect all high volt power supplies
to both the indoor unit and outdoor unit.
Failure to do so could result in physical
injury and/or electrical shock.
When troubleshooting the indoor unit, refer
to the wiring diagram that is supplied with
the equipment. It is located on the back
of the control access panel. If unable to
locate the wiring diagram call the factory
technical service line at (800) 228-9364
and one can be faxed or mailed. Please
have the full model and serial number
