MPC-5 PURGE MODE BYPASS
Whenever the control power (12 or 24 volt DC) has been shut off the system will prompt
you through the purge mode when it is turned back on. This is because the only time the
MPC-5000 should be turned off is after the system has been pickled. Purge Mode prompts
the operator to open the pressure relief and then runs seawater through the system for 20
minutes to clear away the chemicals. Normally, during periods of disuse the MPC-5000 will
remain powered up so that it can do the five day flush cycles, and no storage solution will be
present. If the control power has been interrupted but the system is not filled with storage
solution, Purge Mode can be bypassed by tapping the two left hand buttons at the same time
until the display reads PURGE MODE BYPASSED. The buttons must be pushed at exactly
the same time. You can’t hold one down and then push the other. From Purge Mode By-
passed you can run the system in any mode. 4/20/04
