Piping System
The Rebel piping system varies signicantly between the
multiple possible congurations; heat pump, cooling only, and
modulating hot gas reheat. In spite of this multiplicity there
are some consistent characteristics. All units have a single
circuit with a single or tandem compressor. All units use
an electronic expansion valve (EVI) and a start-up by pass
solenoid valve (SVB).
