Notes:
1. WIRING SHOWN WITH DASHED LINES IS TO BE FURNISHED AND INSTALLED
BY THE CUSTOMER. ALL CUSTOMER SUPPLIED WIRING MUST BE COPPER
ONLY AND MUST CONFORM TO NEC AND LOCAL ELECTRICAL CODES.
CODES MAY REQUIRE LINE OF SIGHT BETWEEN DISCONNECT SWITCH
AND UNIT.
2. WHEN ELECTRIC HEATER ACCESSORY IS USED SINGLE POINT POWER
ENTRY OR DUAL POINT POWER ENTRY IS FIELD OPTIONAL, SINCE
POINT POWER ENTRY OPTION IS THROUGH ELECTRIC HEATER ONLY.
***NOTE: CHOOSE ONLY 1 OF THE FOLLOWING; THERMOSTAT,
ZONE SENSOR, OR NSB PANEL
