Line Set

Field refrigerant piping consists of liquid and suction lines
connecting the condensing unit and the indoor unit. Liquid
and suction service valves are located in a compartment
at the corner of the unit below the control box.
Piping can be routed directly from the service valves or
field supplied elbows can be added to divert the piping as
required.
Refer to table 1 for field-fabricated refrigerant line sizes for
runs up to 50 linear feet (15 m).
