Feed Pump, Pre- Filter and Hose connections
The Sea Water feed should be a marine grade Sea Cock, that you can close the Sea Cock individually.
The sea water inlet should be a scoop type, that the water is pressed in during cruise.
Step 1 Connect the Sea Water intake with a re- enforced ¾” hose to the lower hose barb at the valve at the
Strainer. Connect the outlet of the Strainer with the intake of the feed pump, or, if an Air separator is
used, to the inlet of the Air Separator, which is on 12/24V Systems the inlet of the attached Boost pump.
The outlet of the Air Separator is at the bottom of the housing. The left 8mm Line is to drain over board.
The upper connection of the Valve at the Strainer has to be connected with the outlet of the Carbon
Filter. (FWF System) The inlet of the Carbon Filter must be connected with your boats pressure water.
.
Step 2 Connect the outlet of the Feed Pump with the inlet of the red Pre-Filter. The outlet of the red Filter has to
be connected with the Sea Water inlet at the ETD, marked with E. The outlet, marked with S is the drain
over board.
Step 3 From the ETD Low Pressure outlet draw the supplied 10mm John Guest pipe to the Main Panels LP
Monitor.
Note!!
All connections past the Feed Pump have to be checked carefully, because there is already a
pressure of 7-10 Bar. Tighten the hose cleats carefully and check for leaks by the first use.
Use only hoses capable for 10 Bar pressure
