2. THE CONTROL TRANSFORMER HAS MULTIPLE HIGH VOLTAGE TAPS.
ENSURE WIRE CONNECTIONS ARE CORRECT FOR UNIT SUPPLY VOLTAGE RATING
3. SEE CONTROL DIAGRAM FOR CONTROL TRANSFORMER LOW VOLTAGE CONNECTIONS
4. OPTIONAL; CB1,CB2,BC2 AND ASSOCIATED WIRING IS PRESENT ONLY WITH 2-SPEED EVAPORATOR MOTOR.
5. USE COPPER CONDUCTORS ONLY. UNIT TERMINALS ARE NOT DESIGNED FOR OTHER CONDUCTORS.
THE USE OF OTHER TYPE CONDUCTORS MAY CAUSE DAMAGE TO THE UNIT.
6. SEE ACCESSO RY KIT LITERATURE FOR OPTIONAL CONVENIE NCE OUTLET WIRING DIAGRAM.
7. IF LOW AMBIENT KIT INSTALLED, DISCONNECT CONDENSER MOTOR WIRES (BK,BR,YL) FROM CMC1 (T1,T2,T3)
AND CONNECT TO CORRESPO NDING 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.
Wiring is subject to change. Always refer to the wiring diagram on the unit for the most up-to-date wiring.
