Unit Description

These condensers come with single and dual
compressor options. Single compressor outdoor units
feature a single refrigeration circuit requiring only one
set of refrigerant lines. Dual compressor/dual circuit
models give true stand-by protection; if one
compressor fails, the second will automatically start-
up. During light load conditions, only one compressor
will operate to save energy.
