1.6 CIRCUIT BREAKERS

The Circuit Breakers remove 115VAC
control power only. High voltage cir-
cuitry will still be energized from the
high voltage supply.
REMOVING 115VAC power to or
opening CB4 (3 System chillers) or
CB5 (4 System chillers), removes
power from the evaporator heaters.
This could cause evaporator freeze-up
in low ambient temperatures.
