THIS DEFROST CONTROL BOARD CONTAINS A FIVE MINUTE SHORT CYCLE
PROTECTOR. A FIVE MINUTE DELAY WILL OCCUR BETWEEN COMPRESSOR
OFF/ON CYCLES.

JUMPERED TEST PINS (USE METAL OBJECT), FIELD SPEED-UP CYCLE

1) MOMENTARILY SHORT PINS AND RELEASE TO BYPASS COMPRESSOR OFF DELAY.
2) SHORT FOR 5+ SEC. AND RELEASE FOR FORCED DEFROST.
3) PERMANENT SHORT WILL BE IGNORED.

DEFROST WILL TERMINATE IN 30 SEC. IF DFT OPEN.
DEFROST WILL TERMINATE NORMALLY IF DFT IS CLOSED.

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. USE CONDUCTORS SUITABLE FOR AT LEAST 75 C (167 F).
