The system will support refrigerant runs to the inside unit of up to 100' equivalent feet with a 35' rise included. The units are furnished with sweat connections and are equipped with refrigerant valves and Schrader fittings for charging and taking
pressure readings. The following precau- tions should be made:
•Be certain no burrs remain on the fittings.
•Use only clean refrigeration tubing.
•Use tube benders to guard against kinking.
•Avoid piping on wet and rainy days and insulate suction line. Be certain that plastic end caps remain in place when inserting through wall openings. Isolate tubing from transmitting vibra- tion to the building or unit and avoid contact with sharp edges. Refrigera- tion valves should be wrapped with a wet rag "heat sink" to protect valves while brazing.
