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 airflow
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.
This unit is equipped with a variable speed ECM motor.
The motor is designed to maintain rated airflow up to
the maximum static allowed. It is important that the
blower motor plugs are not plugged in or unplugged
while the power is on. Failure to remove power prior to
unplugging or plugging in the motor could result in
motor failure.
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.
CAUTION
Do not plug in or unplug blower motor
connectors while the power is on. Failure
to do so may result in motor failure.
