7. Add a small amount of vegetable cooking oil to the tank threads and screw on Fleck 9100 control
valve carefully. Alternatively you can use silicone grease, but do not use pipe-joint compound, Teflon
tape, or Vaseline or other petroleum greases to lubricate tank threads.
8. See how the Fleck by-pass is connected. There are in and out arrows on the bypass valve for the inlet
and outlet pipe. Install inlet and outlet piping, drain tubing and brine line tubing. The brine line tube
is included and is shipped inside the brine tank.
Attaching the brine tubing to the brine solution tank & the Fleck 9100 brine valve
9. Begin by sliding the plastic brine injector nut on to the brine tubing by putting the tubing through the
non-threaded side of the nut. Next, slide the black (or clear) compression ring on to the tubing with
the narrower diameter going on first. Then slide the taller, white compression ring on to the tubing
with the wider diameter going on first. The two compression rings should lay flesh against each other
on the tubing. Slide them in to the brine injector nut and place the brine tubing into the brine valve.
Finally, push the brine injector nut, which now has the compression rings inside of it, on to the
threading of the brine valve and rotate the nut clockwise, screwing it on to the brine valve. Tighten it
down to finger tightness. The tubing should be firmly attached and not slide out if pulled on.
