All you have to do is a "Search" and enter Spectra watermaker
and you'll get..........Me! <grin> I've worked on one or two Spectras in my time.
First Shelly, you have a few issues that can lead to a long response here. If you'd like more info you can PM me for my cell number anytime. The suggestion to use soap is not for Bio fouling but for oil
contamination. The SC-2 and SC-3 won't help with oil
fouling. If your membrane is slightly clogged with oil usually your pressures will climb and production will drop. If oil contamination is the real problem and it is not extreme, using about three gallons of either product water, or as I prefer three gallons of distilled water, mix about two to three tablespoons of Dawn dishwater soap in a five gallon bucket. Make sure it is Dawn, it's a better oil cutter
than other soaps. Get out your two pickling hoses. Give your system a good fresh water flush or two first. Then close your thru hull
, attach your pickling hoses, set the yellow valve to the "Service" position, open your pressure relief valve 1.5 to 2 turns. Start your system manually at the toggle switch and let your system run like this for about two hours. When you are done, install new pre-filters and throw out the ones you removed, open the thru hull
, move the yellow handle valve back to the "Run" position, unattached the pickling hoses and re-attach the brine discharge hose and white service
cap, again run your system in the manual mode for about 30-40 minutes with the pressure relief valve still open. After this time slowly close off your pressure relief valve and measure the product water using a graded bucket and a watch. You should be getting around 16gph. Also test your product with your TDS meter. Oil fouling is a tough nut to crack as is Bio-fouling. In my experiance by the time a boat based watermaker is showing signs of either of these condtions it is usually new membrane time. Not to say I haven't seen cleaning
work but it is usually the exception not the rule
and even those that can be saved their life expectancy is drastically reduced. This should be taken into consideration when planning a cruise
Your system going into an Alarm
of "Check the pre-filters now" right after you've installed new filters is most likely because you have either clogged pressure sensors, an incorrect program setting or the sensors have failed. To keep your system running simply disconnect these two sensors temporarily at the 5 and 20 MIcron filter housing until you can have a Spectra trained tech look at this for you. It won't hurt the system but you will lose the GOOD REPLACE function and Feed pump Pressure readings on the control board until the problem is resolved.
90psi on your pressure gauge is not bad depending on the water you are floating in. Normal pressures on your system should be between 90-120psi.
At 90psi a reading of 1020PPMs is indicative of a membrane issue as well.
As I said, a PM to get my cell number is a good idea with your multiple issues. I'll even help you with reading a Volt meter.
