NOTES:<br />
1. SYMBOLS ARE ELECTRICAL <br />
REPRESENTATION ONLY.<br />
2. COMPRESSOR AND FAN MOTOR FURNISHED<br />
WITH INHERENT THERMAL PROTECTION.<br />
3. TO BE WIRED IN ACCORDANCE WITH<br />
NATIONAL ELECTRIC N.E.C. AND LOCAL<br />
CODES.<br />
4. N.E.C. CLASS 2, 24 V CIRCUIT, MIN 40 VA <br />
REQUIRED, 60 VA ON UNITS INSTALLED<br />
WITH LLS.<br />
5. USE COPPER CONDUCTORS ONLY.<br />
6. CONNECTION FOR TYPICAL COOLING ONLY <br />
THERMOSTAT. FOR OTHER<br />
ARRANGEMENTS SEE INSTALLATION<br />
INSTRUCTIONS.<br />
7. IF INDOOR SECTION HAS A TRANSFORMER<br />
WITH A GROUNDED SECONDARY, CONNECT<br />
THE GROUNDED SIDE TO THE BRN LEAD.<br />

CAPACITOR ARE INSTALLED, START<br />
THERMISTOR IS NOT USED.<br />
9. CH NOT USED ON ALL UNITS.<br />
10.IF ANY OF THE ORIGINAL WIRE, AS<br />
SUPPLIED, MUST BE REPLACED, USE THE<br />
SAME OR EQUIVALENT WIRE.<br />
