Re: Dessalator cuts out when flushing

Paul Dowd and Sharon Brown



This is the reply from Dessalator (and quite quick there were too!):


Dear Paul,


Thank you for your inquiry.


If you run the unit without increasing the pressure, it is normal that it shuts after one minute.


The good procedure to flush the water maker when you return on your boat is to turn the rinsing valve located on the low pressure pump, but WITHOUT running the water maker.


You will find the procedure enclosed.


If you have any doubt, you can call for free our engineer, M. Martin de Jong, on Whatsapp. Please find enclosed his contact info.


With our best regards,


Nicolas Bouffartigue

Secretary Dessalator

According to the Dessalator manual the system should shut down after one minute in this mode of operation.  See the excerpt from the manual below.

Fresh water should be always used with no pressure when going through the system (pressure dial turned all the way anti clockwise) and the system should always run with no pressure after a fresh water flush to dump all the fresh water that are in it, before making freshwater from sea water (also with the pressure dial all the way anti clockwise). When running the water maker with the dial all the way anti clockwise, it will shut itself down automatically after 1 minute. Only then, the water maker is ready for use.

When introducing the sterilizer you are operating in this condition.  I believe your system is operating correctly.  You will then go through the flush cycle when you put the system back into service.

Water will go through the membranes with the regulator turned all the way open "anti clockwise".  This position being the normal start position for the Dessalator which allows the high pressure pump to start with little to no head pressure.
