7-1 Low Water Level Light
This indicator lights and the chiller shuts down when the float switch in the reservoir senses that
the water/glycol level has dropped below an acceptable level.
Add enough water/glycol mixture to fill the tank to the operating level, or check the operation of
the automatic water makeup if one is installed. Use a mix that provides freeze protection to at
least 20°F below the process temperature.
7-2 High Refrigerant Pressure Light
This indicator lights if the condensing pressure exceeds 350 psi. The compressor stops and the
pump continues to run until you manually reset the high pressure cut out. Call a qualified
refrigeration service technician or contact the Application Engineering Service Department for
service.
7-3 Low Refrigerant Pressure Light
This indicator lights if the refrigerant pressure drops below a safe level. The compressor stops
and the pump continues to run. The indicator turns off and compressor restarts automatically
when the refrigerant pressure reaches 50 psi.
