7. INSTALL SALT STORAGE TANK OVER-
FLOW FITTINGS AND HOSE
a. Insert the rubber grommet into the 3/4" diameter
hole in the salt storage tank sidewall (See Figure
13).
b. Push the barbed end of the hose adaptor elbow into
the grommet.
c. Measure, cut to needed length and connect the 3/8"
drain line (provided) to the salt storage tank over-
flow elbow and secure in place with a hose clamp.
d. Route the hose to the floor drain, or other suitable
drain point no higher than the drain fitting on the salt
storage tank (This is a gravity drain). If the tank
overfills with water, the excess water flows to the
drain point. Cut the drain line to the desired length
and route it neatly out of the way.
IMPORTANT: For proper operation of the water soften-
er, do not connect the water softener
valve drain tubing to the salt storage
tank overflow hose.

8. CONNECT BRINE TUBING
a. Route the tubing attached to the brine valve assem-
bly out of the brine tank through the hole provided in
the tank sidewall. Use the slot in the brinewell to
hold tubing in place.
b. Connect the end of this tube to the nozzle/venturi
assembly, as shown in Figure 13, using a ferrule nut
(provided). Tighten the nut by hand, then an addi-
tional 1/4 turn with pliers.

9. TEST FOR LEAKS
To prevent air pressure in the water softener and
plumbing system, complete the following steps in
order:
a. Fully open two or more softened cold water faucets
close to the water softener, located downstream
from the water softener.
b. Place the bypass valve (single or 3 valve) into the
"bypass" position. See Figures 4 & 5.
c. Slowly open the main water supply valve. Run
water until there is a steady flow from the opened
faucets, with no air bubbles.
d. Place bypass valve(s) in "service" or soft water
position as follows:
= Single bypass valve: Slowly move the valve stem
toward "service," pausing several times to allow
the water softener to fill with water.
= 3 valve bypass: Fully close the bypass valve and
open the outlet valve. Slowly open the inlet
valve, pausing several times to allow the water
softener to fill with water.
e. After about three minutes, open a hot water faucet
until there is a steady flow and there are no air bub-
bles, then close this faucet.
f. Close all cold water faucets and check for leaks at
the plumbing connections that you made.
g. Check for leaks around clips at softener's inlet and
outlet. If a leak occurs at a clip, depressurize the
plumbing (turn off the water supply and open
faucets) before removing clip. When removing clips
at the softener's inlet or outlet, push the single
bypass valve body toward the softener (See Figure
14). Improper removal may damage clips. Do not
reinstall damaged clips.
