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 the highest sales volume evaporator plus 15 feet of
field supplied lines.
Matching indoor coils require a thermal expansion valve. The refriger-
ant charge may need to be changed for some system combinations,
elevation differences, or total line lengths. See tabular data sheet pro-
vided in unit literature packet for charge requirements. Refer to Applica-
tion Data covering "General Piping Recommendations and Refrigerant
Line Length" (Part Number 247077).
