Pickling and Winterizing with Antifreeze
The watermaker can be stored for periods up to one year in any climate using this procedure.
1. Close the yellow service valve, open the Grey flush valve, and run the feed pump 4 minutes
to effect a complete fresh water flush. Shut the pump and flush valve off.
2. Connect the inlet service hose and put it in the service container or bucket.
3. Turn the service valve to the service position.
4. Pour 2 gallon (8L) of propylene glycol in the bucket.
5. Make sure that the pressure relief valve is OPEN (un-pressurized).
6. Turn on the feed pump until antifreeze begins to show at the brine overboard fitting, then
stop the pump. Add more antifreeze if necessary.
7. Connect the brine discharge service hose and place it in the bucket.
8. Circulate the antifreeze for about five minutes.
9. Stop the pump. Reconnect the brine discharge hose. Restart the pump until the bucket is
empty.
10. Close the seawater intake and the service valve. Drain the strainer and the hose leading to
the inlet module. Disconnect the product tubing and blow any residual water out of the tub-
ing with compressed air. Empty the charcoal filter housing and flush water lines.
