SECTION I: GENERAL
The outdoor units are designed to be connected to a matching indoor
coil with sweat connect lines. Sweat connect units are factory charged
with refrigerant for a nominal sized matching indoor coil plus 15 feet of
field-supplied lines.
Matching indoor coils can be used with a thermostatic expansion valve
(TXV). Refer to the Tabular Data Sheet or to the Technical Guide for
the proper selection.
