. Compressor damage may occur if system is over charged.
. This unit is factory charged with R-22 in accordance with the amount shown on the rating plate. The charge is
adequate for most systems using matched coils and tubing not over 15 feet long. The best performance will be
achieved when the unit operates with a suction gas superheat at the compressor inlet of 5 °F at normal rating
conditions of the air conditioning and refrigeration institute (ARI). This chart may be used to approximate the
charge if ARI rating conditions cannot be obtained. ARI rating conditions are equivalent to DOE test "A"
conditions. See product data literature for required indoor air flow rates and for use of line lengths over 15 Ft.
. Carefully relieve refrigerant pressure within this unit before final disposal.
