4 Control Panel
4.1 Components of the Control Panel
The control panel consists of the following elements:
1. Main power switch:
connects and disconnects the ultracool unit
from the power supply.
2. On-Off switch:
starts up the different elements that make up the
ultracool unit.
3. Water gauge:
indicates the working pressure of the pump.
4. Control thermostat:
indicates the cold water temperature at the
outlet of the ultracool unit and enables it to be regulated.
5. Pump indicator:
this remains lit when the pump is working.
6. Compressor indicator:
this remains lit when the compressor is
working.
7. Water level alarm indicator:
this is lit when the water level in the
tank is too low. It causes the ultracool unit to stop.
8. 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 7ºC (45ºF). To be able to
reach temperatures below that contact an authorised technical
service.
9. Low refrigerant pressure alarm indicator:
this is lit when the
pressure of the refrigerating circuit is below the minimum allowed. It
causes the refrigerant compressor to stop.
