Stopping the Unit

How to stop your X4-7700 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 turn off and go blank.

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

If you turn the START/RUN-OFF switch OFF and then back to the START/RUN position, expect a 4 to 50 second delay between the display going off and coming back on again. This is due to internal processing.
