Product Water tubing
Product water tubing is 1/2” (9.5mm) Parker tubing. See the Parker tube fitting assembly
diagram on pg 14 . Product water goes from the membrane into the pump module manifold
where it passes through the flow meter, the salinity probe and the diversion valve. If the
salinity is good the diversion valve energizes and the product goes to the tank from the
manifold product outlet. If the diversion valve is not energized the product goes back into the
feed water.
Route the product water tube from the
product water outlet fitting on the High Pressure Module
manifold into the top of the tank. Install a tee in the water tank fill or tap a pipe thread into an
inspection port in the top of the tank. Do not feed the water into a manifold or bottom of the
tank. Make sure there is no restriction in this plumbing.
A product sampling tap can be installed along the tank fill hose between the manifold and the
tank connection. If a sampling tap or filling manifold is to be installed on the product water
line, then an “open-before-close” type 3 way valve should be used to ensure that the product
water line is never accidentally pressurized.
If the length of product water tubing supplied with the watermaker is insufficient, use a larger
size hose. Product water
flow restriction will cause reduced output and increased power
consumption and can potentially damage the membrane.
