NOTES:
1. Jumper for 1-3 seconds: Factory Test — The defrost interval timing is reduced by a factor of 0.1 seconds/minute based on the positions of DIP
switches SW1 and SW2 (i.e. 90 minutes will be reduced to 9 seconds).
2. Jumper for 5-20 seconds: Forced Defrost — Defrost runs for 30 seconds if DFT2 is open.
UNIT WITHOUT THRU-BASE CONNECTION KIT
Pass the thermostat control wires through the hole provided in
the corner post; then feed the wires through the raceway built
into the corner post to the control box. Pull the wires over to
the terminal strip on the upper-left corner of the Central Termi-
nal Board (CTB). See Fig. 41.
NOTE: If thru-the-bottom connections accessory is used, refer to
the accessory installation instructions for information on routing
power and control wiring.
