Important!
Your AEC, Inc. warranty does not cover damage from evaporator freeze-up.
Be sure there is enough glycol in the system and that the High/Low thermostat
is set to the correct cutout temperature to prevent freeze-up!
Hot Gas By-Pass Light (1.5 Ton Unit Only)
The Hot Gas By-Pass light turns on when the hot gas bypass
valve is in operation. The OUT1 LED on the controller also lights
when the hot gas bypass valve is in operation.
Pump On Light
The Pump On light, installed on chillers with a pump, lights
whenever the pump(s) operates.
High Refrigerant Pressure Light (1.5 Ton Unit Only)
The High Refrigerant Pressure light comes on if the compressor
discharge pressure exceeds the limit of the high pressure cut-out
switch. The compressor stops but the pump(s) continue to run
until you manually reset the high pressure cut-out switch. Call a
qualified refrigeration service technician or contact the AEC
Service Department.
Low Refrigerant Pressure Light (1.5 Ton Unit Only)
The Low Refrigerant Pressure light comes on if the compressor
suction pressure drops below the limit of the low pressure cut-out
switch. The compressor shuts off, but the pump(s) continues to
run.
The indicator turns off and compressor restarts automatically when
the refrigerant pressure raises to the limit of the low pressure cut-
out switch. Call a qualified refrigeration service technician or
contact the AEC Service Department.
