The overflow line drains away excess water should the tank fill with
too much water or the appliance malfunctions.
A. Connect 1/2-inch I.D. tubing (size CANNOT be
reduced) to the gravity overflow connection. This
tubing is not supplied with the appliance. Route
the overflow line to a drain (or bucket) that is at
least three inches lower than the bottom of the
overflow connection. The gravity overflow line
cannot be run overhead.

The drain line drains away the backwash water as part
of the regeneration cycle.
A. Connect the drain line to the drain end cap (as
shown in Figure 8) with a minimum of 1/2-inch
I.D. tubing (size CANNOT be reduced). This
tubing is supplied with the appliance.
B. Route the drain line to a floor drain, laundry tub, or
other suitable waste receptor. Maintain a minimum
2-inch (50 mm) air gap between the drain line and
the flood level rim of the waste receptor to prevent
back-siphoning. This drain line should make the
shortest run to the suitable drain.
C. The drain line may be elevated up to 8 feet (2.4 m)
from the discharge on the appliance as long as the
water pressure in your system is 40 psi (2.8 bar) or
more. If the drain line is 25 feet (7.6 m) or longer,
increase the drain line to 3/4-inch I.D.
D. The end of the drain line must be equal to or lower in
height than the control valve.
Caution: The drain line must not be kinked, crimped, or
restricted in any way.
