The high refrigeration safety pressure switch shuts off the compressor immediately when the high refrigeration pressure reaches 230 PSI {15.9 bar} without going through pump down during a low pressure cycle. If the high pressure switch trips, it must be manually reset by pressing the “Reset” button on the switch. The compressor can start immediately when this is reset so caution should be exercised.

To reset the high refrigeration safety switch:

✐NOTE: The High Pressure Safety switch may not reset

due to the chiller’s refrigerant state. Allow the refrigerant to cool before attempting to reset.

2Remove the chiller’s right-side panel, as viewed from the control.
