Line Sizing Chart
Refer to the Line Sizing Chart below for selecting the appropriate tubing size for
the length of the piping run. Note that the recommended line size may not match
the connection ports on the Condensing unit and the Evaporator. Refrigeration
grade fittings must be supplied by the installing technician to make the necessary
transitions. Transitions should be made as close to the unit as possible.
Suction line routing must be designed to ensure oil return to the Condensing unit.

Vertical Piping Guidelines
Piping runs should be kept as short and compact as possible. Low-lying areas (oil
“traps”) where oil can accumulate should be avoided. Refer to the following
guidelines with regards to the vertical placement of the evaporator and condensing
units:
