7. If indoor section has a transformer with a<br />
grounded secondary, connect the grounded side<br />
to the BRN lead.<br />
8. When start relay and start capacitor are installed,<br />
start thermistor is not used.<br />
9. CH not used on all units.<br />
10. If any of the original wire, as supplied must be<br />
replaced, use the same or equivalent wire.<br />
11. Check all electrical connections inside control box<br />
for tightness.<br />
12. Do not attempt to operate unit until service valves<br />
have been opened.<br />
13. Do not rapid cycle compressor. Compressor must<br />
be off 3 minutes to allow pressures to equalize<br />
between high and low side before starting.<br />

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