High-pressure hose, to be cut into two parts according to your needs.
To allow a flexible assembly, the high-pressure hose is provided as one piece of 4
meters (13.1 feet) with a V4A high-pressure fitting at both ends. Please fit the
required lengths accurately before cutting the hose.
Note: The high-pressure hose may not be installed with a smaller radius than 6 cm.
Assembly instruction for the two V4A high-pressure hose fittings:
1) Cut the hose with a clean 90º cut.
2) Screw the sleeve nut off the provided high-pressure hose fitting.
3) Wet the outside of the hose with a little bit of washing-up liquid.
4) Turn the sleeve nut onto the hose. Leave a gap of 2 mm between hose and
shoulder of the screw nut to enable the hose expanding in length.
5) Wet the thread nipple of the fitting and the inside of the hose with a little bit of
washing-up liquid.
6) Hold the sleeve nut with a wrench and screw the thread nipple with a second
wrench into the hose.
7) Connect the pressure connection of the high-pressure pump and the entrance of
the membrane housing with a hose. The flow direction of the seawater is indicated
with an arrow on the pressure housing of the membrane.
8) The second high-pressure hose connects the outlet of the membrane housing with
the inlet at the pressure control valve on the control panel.
9) Direct the brine from the outlet of the pressure control valve in the control panel
through the three-way valve no. 4 via the plastic thru-hull fitting over waterline
overboard.
