Hi James, You are correct, depending on the source you look at 1 micro-siemen/cm = to about 0.65 TDS for seawater.  I have corrected my original message. 

This is the EC meter I bought ( example   https://www.ebay.com/itm/OMEGA-ENGINEERING-CDCN-201-CDCN201-RQANS2-/232703669959 )  it is powered by 230 VAC, has adjustable alarm limits (I verified the calibration on mine using some standardized calibrated water), and it has relay output for the alarm and/or bypass valve.  I included some LEDs to show power, and alarm condition but that was just fluff.  I powered it from the Dessalinator CB  so that any time that CB is on the salinity sensor is on.  The relay output switches 24 VDC to the sonalert that has an inline switch that I label "arm / mute" so I can mute the sonalert while the startup cycle does it's thing (i.e. high EC). The bypass switch is labeled "save / discard".  I will draw up a schematic of the system and post it in the files section under Amel SM - Dessalator.  The sensor is plumbed into the product water line as it exits the membranes (next to the original sham sensor).  I think I already posted a picture of that.  My timer for the auto flush circuit is a 24 volt fish feeder 7 day programable timer hooked to a relay.  The wire from the 24 VDC panel for the pressurized water pump passes thru this relay on the Normally Open contacts.  When the timer is in the "ON" mode the relay closes and supplies 24 VDC to the fresh water pump.  When I leave the boat I place the flush valve in the the "flush" position and set the Timer to "Auto" mode so that when the timer commands, the relay closes, energizing the fresh water pump for the period programmed into the timer.  Once the flush is complete the power to the fresh water pump is interrupted by the relay contacts opening.  So the pressurized water system is not always pressurized lest a leak flood the boat.  It is only pressurized during relay closure.

We arrived on Kokomo today after wintering her for 6 months in Greece. When I turn on the fresh water breaker, the pump does not start and the breaker trips after about 2-3 seconds..

The pump was working perfectly before we left, so I’m assuming it has something to do with the pump sitting for 6 months.

Any ideas on how to get her Re-started?

Respectfully;

Dean,

I had the same problem and I installed in the saltwater line a cane so I can close the saltwater flow safely and clean the electrovalve which does close tight due to salt remains.

It is bad designed by Amel but ..,

Hi Mohammad,
You are absolutely correct. When I open the valve and turn on the anchor wash pump then water flows freely into the toilet. The line retains water when I turn the anchor wash off, and the toilet can be used, although I suspect it will lose prime over a short period. 

However as soon as the anchor wash is turned on again the toilet starts to fill immediately. This seems like a poor situation really.

I guess the saltwater flush mode really needs to be treated as a degraded mode of operation rather than an alternative mode of operation you could choose when on an ocean crossing for example. 

Anyway, I now understand the operation. Thanks Mohammad.
Cheers

Hi Bil,

If you are referring to the hole that sits at the very base of the mast, that hole is the drain hole for water that gets into the mast. I wonder if it is able to take the loads of a kicker. I also noticed the later 54’s do not have the same “hole-arrangement” at the underside of the boom as the early ones.

I do love your remark about the table behind the steering chair. I wondered the same thing. That thing must be the number 1 design flaw for the Amel 54. I actually removed it. That makes the cockpit much roomier as well. We now use a small foldable table if we need to support our drinks…

I was thinking about this thing to put against the back wall of the cockpit:

But maybe I will just change the way the original table is designed and make it a bit lighter as well.

Hi all,
i decided to test the operation of our optional seawater flush on the forward head. I’ve never used it before and In the absence of any instructions in the user manuals, I opened the seawater valve and tried to flush. There is no seawater being pulled through at all. 

Can anyone advise if there is an additional step I need to do to make the seawater flush work.
I know it worked when we bought the boat because it was checked off by Olivier on survey, so I’m sure I must be missing something.
Thanks guys
