Suction Line Piping Condensing unit below evaporator

Evaporator

Pitch down 1/2" (13mm) per 10 ft. (3m)

NOTE

When installing remote condensing units below the evaporator, the suction gas line should be trapped with an inverted trap to the height of the evaporator. This prevents refrigerant migration to the compressors during off cycles. Maximum recommended vertical drop to condensing unit is 15 ft. (4.6m).
