SERVICE HINTS
1.Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system, which shortens equipment service life, as well as, increasing operating costs.
2.Check all power fuses or circuit breakers to be sure that they are the correct rating.
3.Periodic cleaning of the outdoor coil to permit full and unrestricted air flow circulation is essential.
