Optional facto- ry insulation for the 19XRV is available for the evaporator shell and tube sheets, suction elbow, compressor motor, and motor refrigerant drain line(s). Insulation applied at the factory is 3/4 in. (19 mm) thick and has a thermal conduc- tivity K value of (0.28 • Btu • in)/hr • f2 • °F [(0.0404 • W)/ (m • °C)]. Insulation conforms with Underwriters’ Labora- tories (UL) Standard 94, Classification 94HBF.
