5.10. Overflow line connection
In the event of a malfunction, the brine tank overflow fitting will direct “overflow” to the drain instead
of spilling on the floor. This fitting should be on the side of the cabinet or brine tank. Most tank
manufacturers include a post for the tank overflow connector.
To connect the overflow line, locate the hole on side of tank. Insert overflow fitting into tank and
tighten with plastic thumb nut and gasket as shown below. Attach a length of 12.7 mm (1/2") I.D.
tubing (not supplied) to fitting and run to drain.
Do not elevate overflow higher than overflow fitting.
Do not tie into drain line of controller unit. Overflow line must be a direct, separate line from overflow
fitting to drain, sewer or tub. Allow an air gap as per drain line instructions.
5.11. Brine line connection
The brine line from the tank connects to the valve. Make the connections and hand tighten. Be sure
that the brine line is secure and free from air leaks. Even a small leak may cause the brine line to drain
out, and the conditioner will not draw brine from the tank. This may also introduce air into the valve,
causing problems with the valve operation.
