SERVICE
SERVICE HINTS
1. Caution homeowner to maintain clean air filters at tall
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.
UNBRAZING SYSTEM COMPONENTS
If the refrigerant charge is removed from a scroll
equipped unit by bleeding the high side only, it is
sometimes possible for the scrolls to seal, preventing
pressure equalization through the compressor. This may
leave low side shell and suction line tubing pressurized.
If the brazing torch is then applied to the low side while
the low side shell and suction line contains pressure, the
pressurized refrigerant and oil mixture could ignite when
it escapes and contacts the brazing flame. To prevent this
occurrence, it is important to check both the high and low
side with manifold gauges before unbrazing.
WARNING
Both the high and low side of the scroll
compressor must be checked with manifold
gauges before unbrazing system components.
Failure to do so could cause pressurized
refrigerant and oil mixture to ignite if it escapes
and contacts the brazing flame causing property
damage, bodily harm or death.
