5.3 Line Set Installation
The installer must supply a line set (1/4” liquid line, 3/8” gas line) suitable for use with R410a refrigerant to connect
the indoor unit to the outdoor unit.
The maximum allowable length of the line set is 50 feet. The installer must
braze the lines to the dehumidifier and the condensing unit. The gas (suction) line must be insulated to prevent the
formation of condensation on the outside of the line.
Line Set Isolation — The following illustrations are examples of proper refrigerant line set isolation.
