Water line Connection
The installation of a bypass valve system is recommended to
provide for occasions when the water conditioner must be
bypassed for hard water or for servicing.
The most common bypass systems are the Autotrol Series 1265
bypass valve (Figure 1) and plumbed-in globe valves (Figure 2).
Though both are similar in function, the Autotrol Series 1265
bypass offers simplicity and ease of operation.

Drain line Connection
NotE:
Standard commercial practices are expressed here.
local codes may require changes to the following
suggestions.
1. Ideally located, the unit will be above and not more than
20 feet (6.1 m) from the drain. For such installations, using
an appropriate adapter fitting, connect 1/2 inch (1.3 cm)
plastic tubing to the drain line connection of the
control valve.
2. If the backwash flow rate exceeds 5 gpm (22.7 Lpm) or if
the unit is located more than 20 feet (6.1 m) from drain, use
3/4 inch (1.9 cm) tubing for runs up to 40 feet (12.2 m). Also,
purchase appropriate fitting to connect the 3/4 inch tubing
to the 3/4 inch NPT drain connection.
3. If the unit is located where the drain line must be elevated,
you may elevate the line up to 6 feet (1.8 m) providing the
run does not exceed 15 feet (4.6 m) and water pressure
at conditioner is not less than 40 psi (2.76 bar). You may
elevate an additional 2 feet (61 cm) for each additional
10 psi (0.69 bar).
4. Where the drain line is elevated but empties into a drain
below the level of the control valve, form a 7 inch (18 cm)
loop at the far end of the line so that the bottom of the loop
is level with the drain line connection. This will provide an
adequate siphon trap.
5. Where the drain empties into an overhead sewer line, a
sink-type trap must be used.
IMPortANt: Never insert drain line into a drain, sewer line
or trap. Always allow an air gap between the
drain line and the wastewater to prevent the
possibility of sewage being back-siphoned into
the conditioner.
Right Way

Brine line Connection
It will be necessary to install the brine line to the brine fitting
on the valve (3/8-inch NPT).
Be sure all fittings and connections are tight.
overflow line Connection
In the absence of a safety overflow and in the event of
a malfunction, the BRINE TANK OVERFLOW will direct
“overflow” to the drain instead of spilling on the floor where it
could cause considerable damage. This fitting should be on the
side of the cabinet or brine tank.
To connect overflow, locate hole on side of brine tank. Insert
overflow fitting (not supplied) into tank and tighten with plastic
thumb nut and gasket as shown (Figure 4). 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 3 inches
(7.6 cm) below bottom of 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 (Figure 3).
