Flush Cycle Adjustment

Before shipping from the factory the Ventura watermaker flush cycle is set to factory default settings. After initial start up, and annually thereafter, the flush cycle parameters must be ad- justed to ensure that the salt water is thoroughly flushed out of the machine while at the same time using the least amount of fresh water possible. Check the flush by closing the sea cock. If the system alarms “Check sea strainer” insufficient water is being supplied from the vessels fresh water system. If the fresh water supply is insufficient sea water will be drawn in to make up the difference and the system will not be properly flushed. After checking the flush water flow adjust the “Flush Duration” from the Programming Function on the display. Set the Flush duration so that the Flush comes to an end just as the salinity of the water going overboard drops below 1000 ppm or no longer tastes brackish.

Automatic Store Cycle

Warning! Proper understanding of the Spectra flush system and the vessel’s fresh water sys- tem configuration is mandatory for extended Auto Store cycles. The flush cycles must not be allowed to drain all the fresh water from the vessel or damage to the vessel’s systems may oc- cur.

•Make sure there is enough water in the fresh water supply system to supply the water- maker for more than the expected time of operation in the “re-flush every 5 days” mode. The Ventura 150 requires about 2.5 gallons (10 liters) every 5 days.

•Make sure that the pressure water supply is on and will stay on during the flush mode (If this is not possible contact your certified dealer.).

•Make sure that the pressure relief valve is closed. It should be closed if the system was just used to make water. The auto flush may not operate if the valve is open.

•The power for the system must remain on during the auto flush mode. Turning off the power will disable the auto store function and damage may occur.

•Pressing the Auto Store button momentarily will start a flush and then activate the 5 day flush cycle. The feed pump will start, the flush water solenoid will open and the display will read “FRESH WATER FLUSH” with a countdown timer. After 5-7 min- utes 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 3 seconds will engage a 1 time flush. The system flushes as described above but will not re-flush every 5 days. Dis- play will read “FRESH WATER FLUSH” with a countdown timer, then the default dis- play when finished.

•Pressing the Stop button will cancel the auto store mode.
