How do I troubleshoot the system?

The system will auto correct itself and adjust automatically to changes in the flow. If troubleshooting is required (“Malfunction” or “System Error” messages), then –

Malfunction:  (i) shut the unit off, ensure that the CDU is fully primed, and turn it on again; if note resolved, (ii) replace CDU with a fully primed one.

System Error:  (i) shut the unit off and on again; if not resolved, (ii) replace CDU with a fully primed one.

Follow IFU instructions, as applicable.
