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.
