NOTES:
1. COMPRESSOR AND FAN MOTOR FURNISHED
WITH INHERENT THERMAL PROTECTION.
2. TO BE WIRED IN ACCORDANCE WITH
NATIONAL ELECTRIC CODE (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.
8. CHECK ALL ELECTRICAL CONNECTIONS
INSIDE CONTROL BOX FOR TIGHTNESS.
9. DO NOT ATTEMPT TO OPERATE UNIT UNTIL
SERVICE VALVES HAVE BEEN OPENED.
10.WHEN DTS, LPS AND HPS ARE NOT
REQUIRED, A JUMPER WILL BE INSTALLED
BETWEEN Y AND T1 ON THE DEFROST
BOARD.
MAY BE FACTORY OR FIELD
