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 match-
ing indoor coil plus 25 feet of field supplied lines.
Matching indoor coils are available with a thermostatic expansion valve or an orifice

responsibilities to ensure compliance.
