Warning! Proper understanding of the Spectra flush system and the vessel’s fresh water system
is mandatory for extended use of Auto Store. The flush cycles must not be allowed to drain all the
fresh water from the tank or damage to the vessel’s systems and the watermaker may occur.
As described in Normal Operation and Fresh Water Flush, on page 43, the Auto Store function
flushes the watermaker at programmed intervals. As long as the watermaker is flushed with fresh
water every 5 days (30 days with the Z-Ion) you need not store the system with chemicals.

Make sure there is enough water in the fresh water tanks to supply the watermaker for more
than the expected time of operation in the Auto Store mode. If there isn't enough fresh water
in your tank, seawater will be drawn in to make up the difference, and the system will not be
completely fresh water flushed. To prevent the intake of sea water, close the intake seacock.
The Catalina 340 Z requires about 7 gallons (26 liters) for each flush. The boat’s pressure water
supply must be on and stay on while the system is in Auto Store mode. If these conditions can-
not be met, then pickling with SC-1 storage chemical or propylene glycol is preferable.

Make sure the pressure relief valve on the Clark Pump is closed.

The system must be continually powered during the Auto Store mode. Turning off the power
will disable the automatic fresh water flush and damage may occur.

Pressing the Auto Store button once will flush the system and then activate the flush interval
cycle: The display will read “FRESH WATER FLUSH” with a countdown timer. The feed pump will
run at flush speed to limit the flow rate to 1.5 GPM. After 5 minutes (adjustable) the pump will
stop, the display will read “FLUSH TIMER INTERVAL,” and the countdown timer will reflect the
number of hours until the next flush.

Pressing and holding the Auto Store button for 5 seconds will engage a one-time flush. The
display will read “FRESH WATER FLUSH” while flushing, then the default display will appear
when finished. The system will not re-flush at programmed intervals.

Pressing the Stop button will cancel the Auto Store Mode.
Flush Adjustments
The Catalina flush duration is set to a factory default of 6 minutes, which is usually the right
amount of time to ensure that sea water is thoroughly flushed out of the watermaker using the
least amount of fresh water. However, due to different lengths of hose runs, different rates of
flow, and different pressures in shipboard fresh water systems, the flush duration can be opti-
mized for your boat.
Detailed instructions about how to access the programming function and set the flush duration can
be found on page 74, Programming From the Display. Set the Flush Duration so that the fresh wa-
ter flush comes to an end just as the salinity of the brine discharge drops below 1000 PPM, or no
longer tastes brackish. Since the flush duration can only be adjusted in round minutes, you may
want to lessen the duration to 5 minutes, to save water, or increase to 7 minutes to ensure a thor-
ough flush.
