WARNING Service valve gauge port may not be equipped with Schrader valve (valve core). To prevent personal injury, make sure valve stem is back-seated (counterclockwise) before removing cap. Wear safety glasses and gloves when handling refrigerant.
CAUTION 1. Compressor damage may occur if system is over charged. 2. 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. 3. Carefully relieve refrigerant pressure within this unit before final disposal.

-NOTES1. Symbols are electrical representation only. 2. Compressor and fan motor furnished with inherent thermal protection. 3. To be wired in accordance with National Electric N.E.C. and local codes. 4. N.E.C. class 2, 24V circuit, min. 40 VA required, 60 VA on units installed with LLS. 5. Use copper conductors only. 6. Connection for typical cooling only thermostat. For other arrangements see installation instructions. 7. If indoor section has a transformer with a grounded secondary, connect the grounded side to the BRN lead. 8. When start relay and start capacitor are installed, start thermistor is not used. 9. CH not used on all units. 10. If any of the original wire, as supplied, must be replaced, use the same or equivalent wire. 11. Check all electrical connections inside control box for tightness. 12. Do not attempt to operate unit until service valves have been opened. 13. Do not rapid cycle compressor. Compressor must be off 3 minutes to allow pressures to equalize between high and low side before starting. 14. Wire not present if HPS, LPS, DTS or CTD are used. 15. Use conductors suitable for at least 75°C (167°F). 320918-401 REV. D
