ELEVATION SERIES CIM CUBER HIGH TEMP SAFETY
60
High Temp Safety
The High Temp Safety is a bi‐metal thermostat strapped to the line at the outlet of the Hot Gas
Valve. Should the Hot Gas Valve stick open and the refrigerant line reach 180 degrees F., the
High Temp Safety would open, dropping power to the Contactor and shut down the Compres‐
sor. When the line temperature drops below 120 degrees F., the contacts of the Safety will close,
allowing power to the Contactor.
Note: 48” units have two high temp safety switches connected in series, should either hot gas
circuit trigger a switch, it will shut down the compressor.
Troubleshooting
Should the Compressor not run with the R2 relay LED illuminated, verify if High Pressure Cutout
is closed and Contactor coil is good. The discharge line from the Hot Gas Valve should be cool to
the touch during a freeze cycle. With a line temperature below 120 degrees F. (confirming hot
gas valve is closed), the contacts in the High Temp Safety should be closed. Disconnect both
leads of the High Temp Safety and check for continuity. If open with a cool line, the safety will
need to be replaced.
