Stopping the Unit

How to stop your X4-7300/7500 refrigeration unit

Step 1: Flip the Switch

Place the START/RUN-OFF switch in the OFF position. The unit will shut down immediately while the system completes a shutdown sequence.

Step 2: Confirm Shutdown

The engine will stop, and the display will go blank once the shutdown sequence is complete.

Valve Closure on Shutdown

During the shutdown sequence, the system will close the compressor suction modulation valve (CSMV) and evaporator expansion valve (EVXV) to 0% open before turning off.

Restart Delay

Due to internal processing, if you turn the START/RUN-OFF switch OFF and then back to the START/RUN position, there will be a 4 to 50 second delay between the display going off and coming back on again.
