Installation Instructions
Connect Fittings to the Vessel
Connect the inlet end of the flow meter (Item 10) to the meter adapter which is threaded into the outlet elbow (Item
9), and secure it with the red clip. The flow direction is indicated on the body of the meter.
Connect the drain valve union (Item 11) to the union at the sideport near the top of the vessel (Item 1).
Connect the inlet union (Item 7) to the union at the bottom of the vessel (Item1).
NOTE: Use a wrench to hold the vessel’s side port when tightening a fitting, movement of the port could
damage the shell and/or the port.
Position the hardware assembly and vessel bottom head against the wall and mark the four mounting bolt locations.
Installing the Membrane Element (Item 7):
Lay the assembled vessel and fittings on a horizontal surface.
Cut open the sealed bag of the filter element at the end where the center tube is open. Lightly lubricate the center
tube with the supplied silicone.
Insert the filter element into the bottom of the vessel, with the open end of the center tube first, and removing the
plastic bag as it goes in. A slight resistance will be felt at the last inch of insertion, as the seals on the adapter are
compressed into the center tube of the element.
Install the square cut seal into the groove below the stainless steel ring at the bottom end of the vessel. The seal
should be lubricated lightly on the ID surface only.
Insert the spacer spring (Item 3). About ¼” of compression is required to compress it beyond the square cut seal.
Install the bottom closure.
a. Using both thumbs, apply equal pressure on opposite sides of the head to force it into the vessel, clearing the
retaining ring groove.
b. Carefully insert the retaining ring into the groove. This is done by inserting the lead end of the spiral ring (the end
without the bent tab) into the stainless steel retaining ring groove located in the shell, slowly pushing the remaining
turns into the shell.
c. Check that the spiral retaining ring is fully seated in the groove. If it is not, remove it and check for foreign
materials that would cause the spiral ring to not fully seat.
Mounting the Assembly on the Wall:
Install four ¼” bolts at the positions previously marked. Leave enough clearance between the wall and the bolt
heads to permit the mounting brackets to be slid into place.
NOTE: Bolts larger than ¼” may not fit through the keyhole openings in the mounting brackets.
Tighten the four wall mounting bolts.
Install the other meter adapter into the meter assembly and fully insert the red clip.
Plumbing Connection:
Connect the supply water to the inlet flow control, and complete supply plumbing. Couple the inlet union.
Connect the drain line plumbing to the drain flow control and couple the drain union.
Connect the meter adapter to the outlet plumbing and couple the outlet union.
NOTE: If installing with the backflush kit, complete the plumbing between the outlet tee and the backflush
tank (see Figure 2). The backflush tank pre-charge should be adjusted to 20 psi. If installed, the backflush
tank isolation valve should be closed.
