NOTES:
1. REPLACEMENT WIRE MUST BE SAME SIZE AND TYPE OF INSULATION AS ORIGINAL (USE COPPER CONDUCTORS ONLY).
2. THE CONTROL TRANSFORMER HAS MULTIPLE HIGH VOLTAGE TAPS.
ENSURE WIRE CONNECTIONS ARE CORRECT FOR UNIT SUPPLY VOLTAGE RATING
3. 208/230V SUPPL Y POWER UNITS ARE FACTORY CONNECTED TO THE CONTROL TRANSFORMER 240V TAP.
MOVE WIRE CONNECTION FROM 240V TAP TO 208V TAP WHEN 208V POWER SUPPLY IS USED.
4. SEE CONTROL DIAGRAM FOR CONTROL TRANSFORMER LOW VOLTAGE CONNECTIONS
5. OPTIONAL; CB1,CB2,BC2 AND ASSOCIATED WIRING IS PRESENT ONLY WITH 2-SPEED EVAPORATOR MOTOR.
6. USE COPPER CONDUCTORS ONLY. UNIT TERMINALS ARE NOT DESIGNED FOR OTHER CONDUCTORS.
THE USE OF OTHER TYPE CONDUCTORS MAY CAUSE DAMAGE TO THE UNIT.
7. SEE ACCESSORY KIT LITERATURE FOR OPTIONAL ELEC HEAT AND CONVENIENCE OUTLET WIRING DIAGRAMS.
8. IF LOW AMBIENT KIT INSTALLED, DISCONNECT CONDENSER MOTOR WIRES (BK,BR,YL) FROM CMC1 (T1,T2,T3)
AND CONNECT TO CORRESPONDING BK,BR,YL WIRES ON LOW AMBIENT HARNESS (INSULATED MALE QUICK CONNECT).
ALSO CONNECT LOW AMBIENT HARNESS WIRES (BK,BR,YL) (INSULATED FEMALE QUICK CONNECT) TO T1,T2,T3 ON CMC1.
