A5MSX-2009 Application Information Refrigerant Piping Work Piping Length and Elevation If the pipe is too long, both capacity and reliability of the unit will drop. As the number of bends increases, resistance to the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective.
Page 20
Application Information A5MSX-2009 Piping Work • Do not use contaminated or damaged copper tubing. Do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubings and coils until you are ready to connect suction or liquid line into valves or fittings.
Page 21
A5MSX-2009 Application Information Piping Connection To The Units • The outdoor unit is equipped with two to four sets of flare joints depending on O/D unit model. Refer to table below for flare joint size and location. • In the case where gas pipe from the indoor unit does not match the outdoor flare joints, two different flare joint connectors are provided.
