1.REPLACEMENT W IRE MUST BE SAME SIZE AND TYPE INSULATION AS ORIGINAL (AT LEAST 105°C) USE COPPER CONDUCTOR ONLY.
2.TO CHANGE EVAPORATOR MOTOR SPEED MOVE WHITE AND YELLOW
LEADS FROM EM"2" AND "3" TO "4" AND "5". IF BOTH LEADS ARE ENERGIZED, THE HIGHER SPEED SETTING IS USED.
3 FOR 208 VOLT TRANSFORMER OPERATION MOVE PURPLE W IRES FROM TERMINAL 3 TO TERMINAL 2 ON TRANSFORMER.
4.START ASSIST FACTORY EQUIPPED WHEN REQUIRED
5.USE COPPER CONDUCTORS ONLY
++ USE N.E.C. CLASS 2 WIRE
6.CRANKCASE HEATER AND CRANKCASE HEATER SWITCH FACTORY INSTALLED OPTION.
