264 Chapter 19 Chiller
Main power switch: Connects and disconnects the ultracool unit from the power
supply.
On/Off switch: Starts up the different elements that make up the ultracool unit.
Water gauge: Indicates the working pressure of the pump.
Control thermostat: Indicates the cold water temperature at the outlet of the
ultracool unit, and enables it to be regulated.
Pump indicator: The indicator remains lit when the pump is working.
Compressor indicator: The indicator remains lit when the compressor is working.
Water level alarm indicator: The indicator is lit when the water level in the tank is too
low. This condition causes the ultracool unit to stop.
Low flow/temperature control indicator: This flow control can stop the compressor
when there is no water circulation through the external water circuit. In this case,
some flow still circulates inside the chiller. The temperature control can also stop the
compressor when you try to reach water temperatures below 7° C (45° F). To be able
to reach temperatures below that, contact your HP Indigo service center.
Low refrigerant pressure alarm indicator: This indicator is lit when the pressure of
the refrigerating circuit is below the minimum allowed. It causes the refrigerant
compressor to stop.
the refrigerating circuit is higher than the maximum allowed. It causes the refrigerant
compressor to stop.
