In the event of a sensor failure resulting in a shut down due to a false alarm, the failed sensor
can be overridden using the programming function on the display (page 74). High Pressure, Ser-
vice Prefilter, System Stalled (airlock), and Salinity Probe Failed can all be overridden and the sys-
tem will still run automatically with all other functions intact. Be absolutely certain that the alarm
is false before overriding the automatic controls.
In the event of a complete MPC control failure, the system may be operated manually using the
Manual/Auto/Service switch on the MPC Control Box. Automatic controls and water monitoring
are disabled in manual mode, so the diversion valve will send all of your product water overboard
through the brine discharge. The diversion valve must be bypassed, and product water must be
routed directly to the tank from the membrane product water outlet.
Bypass the diversion valve as follows (see photos below):

Disconnect the 1/4 inch tube from the end of the membrane pressure vessel. This tube
connects the membrane product outlet to the diversion valve manifold.

Disconnect the product-to-tank tube from the diversion valve manifold and connect it di-
rectly to the membrane product outlet.

Taste or sample the product water before sending it to a tank. Always discard the product
water for the first few minutes of operation, as the initial product water from the system
may not be potable.

Test the water with a handheld salinity meter or taste it regularly to ensure water quality.

To shut down manually, set the switch on feed pump module to RUN AUTO.

To manually flush, collect 7 gallons of product water in a container. Connect the inlet service
hose to the Quick Connect service connection on the Z-Ion/fresh water flush module, and put
the other end of the hose in the bucket of water. Start the feed pump with the toggle switch
on the feed pump module set to Service. Run the feed pump until the bucket is empty, then
flip to toggle switch back to RUN AUTO. Disconnect the inlet service hose and replace the fresh
water flush hose.
