In the event of a malfunction, the regenerant TANK OVERFLOW will direct
“overflow” to the drain instead of spilling on the floor. This fitting should be
on the side of the cabinet or regenerant tank. Most tank manufacturers
include a post for the tank overflow connector.
To connect the overflow line, locate hole on side of tank. Insert overflow
fitting into tank and tighten with plastic thumb nut and gasket as shown
(Figure 9). Attach length of 1/2-inch (1.3-cm) I.D. tubing (not supplied) to
fitting and run to drain. Do not elevate overflow line higher than overflow
fitting.
Do not tie into drain line of control 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.

Air Gap
Drain
NOTE: Waste connections or drain outlet shall be designed and constructed
to provide for connection to the sanitary waste system through an air-gap of 2
pipe diameters or 1 inch (22 mm) whichever is larger.
WARNING: Never insert drain line directly into a drain, sewer line, or
trap (Figure 8). Always allow an air gap between the drain line and the
wastewater to prevent the possibility of sewage being back-siphoned
into the conditioner.
