I have no idea where the membranes are, and if I did I'm sure they are long gone.
I cleaned out the lazarette and took this picture. It's a lot of "stuff". So Tellie (and others), where would you start? I have the membrane vessel assembly and it's not shown here. It's two tubes.
I'm not at the boat now, but I have a lot of pictures. Obviously, I don't want to buy membranes until I know that the system is worth saving. What's the first thing I should do?
First the best advice is the one Aparrotwind gave. Get the manual and read it first. In the meantime I'd like to know what the red tag on the pressure relief valve knob says. Most likely an indication of if and when the unit was pickled. If so that is a step very few owners or mechanics do and will clue you into that this is probably a well maintained system. Remember if you start to run this system and intend to let it sit for more than a week or two that you should be ready to fresh water flush it regularly or re-store the system (THIS IS WHERE THE MANUAL COMES IN REAL HANDY) But if you're anxious, first make sure you change out all the pre-flters (blue housings) make sure the thru hull
valve is open. Open the pressure relief valve (you do not want to run this system under pressure yet. Damage to the membranes will occur if they are pressurized with storage
solution in the system) Locate the brine discharge. It should lead to a thru hull
fitting just above the waterline outside the boat. Sometimes people install a valve on this thru hull
, make sure it is open if there is one. Flip the breaker that feeds the watermaker. The system should light up on the board shown. Locate the start button and the off button, also be ready to shut off the breaker if things go funny
and the off switch does not work. Open the red cap on the CAT pump and make sure the oil
level is correct. Start the system (with the pressure relief valve open) The system should start running and the Baldor motor
shown should be turning the CAT pump. If all sounds normal ad there are no leaks
and the pressure gage is in the lower psi levels (80psi or lower) go check the brine discharge thru hull
and check to see if there is water flowing over board. If it is let the system run like this for about 30 minutes to flush out the storage
solution. After it has run for 30 minutes, slowly and I mean slowly start to close off the pressure relief valve knob clockwise. Watch the pressure gage. When it hits 200psi stop and wait a few moments and observe the system for leaks
raise the pressure about 100psi in increments and observe and listen. If you can get the system up to about 800psi you're doing good. I believe that system monitors the TDS readings and will show a red or green light. If red the TDS is too high and the unit is sending the product water overboard
. If green it will divert it to your tanks. Green is GOOD. I can't se in your pic but there might b a flush button. If there is after you have shut down the system push it and the system will give itself a fresh water flush. If you can get this far there is a very good chance you're in business. The other issue you might encounter is the salinity probe does not work. This is common in systems that have sat for long periods of time. Of course the two membranes may be shot. But these things are worth replacing in relation to the value of this watermaker. If you don't have the manual contact Sea Recovery and they'll get you one. Good Luck and let us know how it works out.
