3) Rotate the socket (outer part) anti clock wise on to the hose until hose bottoms. Back the hose out
½ turn to allow for expansion of the hose during assembly.
4) Apply dishwashing liquid mixed 1:1 with water on to the nipple (inner part) of the high-pressure fitting
and the inside of the hose.
5) Hold the socket preferably in a vice and screw the nipple all the way into the hose. The straight fitting
is supplied with a hexagonal plug as an assembly tool.
Run one of the high-pressure hoses from the output of the HP pump (O ring sealed fitting) to the O ring sealed
fitting at the end of the membrane that is marked IN.
CAUTION: A minimum hose length of 3 feet / 1 m is required for pulsation dampening. The hose can be
coiled where needed.
Run the second high-pressure hose from the outlet of the RO membrane housing to the pressure control
valve in the control panel. Do not over tighten the high pressure fittings. They are O-ring sealed and need
little torque to lock only.
CAUTION: When connecting the high pressure hose to the membrane housing (s), avoid over tightening.
The fitting is O-ring sealed and does not require much torque.
PRODUCT WATER TUBING
Connect the blue product water tubing or the 1/2" vinyl hose from the center fittings of the membrane
housing(s) to the bottom inlet of the flow meter, in the control panel. Connect the tubing or hose from each
output port of the 3-way valve to your water tank and to the taste/test station of your choice.
CAUTION: Under no circumstances should the product water line be allowed to become blocked while the
system is running. Do not install shut-off valves anywhere in this line.
CAUTION: Do not allow chlorinated water from your storage tank to flow back into the R.O. membrane.
You may directly “T” your product water line into the tank vent (Refer to the Flow Diagram). This avoids
chlorinated water to back flow from your water tanks into the R.O. membrane and does not require a new
fitting in your tank. This solution requires a vent of sufficient diameter as the product water will have to flow
against the escaping air. If the product line must be installed below tank water line, an optional non- return
valve should be installed.
An existing hand pump style spigot, with a check valve only can be used as test station. If using this type of
spigot for two sources (tank and test), install low-pressure non-return valves in the tank- and product line
and “T” both into the existing hand pump spigot.
