Overview
This guide covers the criteria for when the CO2 Early Run Out/Leak alert will activate, as well as the steps to troubleshoot the issue or diagnose a potential component failure in a Countertop 1.5 with compact chiller.
Alert Details
CO2 Early Run Out/Leak - This alert is triggered when the CO2 High Switch is reading low, when the CO2 inventory calculation is above 40% remaining. This could be due to an incorrect tank size selected during restock, CO2 High Pressure Switch connection issue, CO2 leak, or a failed High Pressure Switch.
