(N.E.C.) AND LOCAL CODES.
3. N.E.C. CLASS 2, 24 V CIRCUIT, MIN. 40 VA REQUIRED.
4. USE COPPER CONDUCTORS ONLY FROM DISCONNECT TO UNIT.
5. MUST USE THERMOSTAT AND SUB-BASE AS STATED IN PRE-SALE
LITERATURE.
6. IF INDOOR SECTION HAS A TRANSFORMER WITH A GROUNDED
SECONDARY, CONNECT THE GROUNDED SIDE TO "C" ON THE
CIRCUIT BOARD.
7. IF ANY OF THE ORIGINAL WIRE, AS SUPPLIED, MUST BE REPLACED,
USE THE SAME OR EQUIVALENT WIRE.
