System Installation
8. Connect the cold water supply to the inlet port of the water
softening system’s control valve. When constructing the sup-
ply line, install an inlet water isolation valve and plumbing union
fitting (user supplied) in the supply line of the control valve and
close the isolation valve. The union fitting should be located
between the isolation valve and the system’s inlet port. For
LCTA-150 series systems where installation plumbing is con-
structed of copper, a 11/2" MNPT X 1' copper pipe plumbing
adapter assembly is included to assist in connection of the
inlet water. Apply plumbing tape to MNPT threads and install
adapter assembly into control valve inlet port.
9. Install an inlet water sample port in the supply line and close it.
10. If risk of vacuum exists, install Watts # 0556031 vacuum
relief valve in the supply line to protect the system against
vacuum damage.
11. Connect the outlet water connection of the water meter to
the water line requiring softened water. When constructing
this outlet water line, install an outlet water isolation valve and
plumbing union fitting (user supplied) in the outlet line and
close the isolation valve. The union fitting should be located
between the outlet of the control valve and the outlet
isolation valve.
12. Install an outlet water sample port on the outlet water line of
the system and close it.
13. For LCTA-150 series systems, install a bypass valve between
the inlet and outlet plumbing water lines and close it.
14. If not already factory installed on the control valve, attach the
drain line flow controller directly to the control valve’s drain
port. See pages 12-13 for Drain and Brine Connection Detail.
The flow arrow on the drain line flow controller must point
towards the drain receptacle. Only plumbing tape is allowed
on the drain line flow controller fitting threads.
WARNING
!
Operating a system without a drain line flow controller will
cause all media to flow out of the system through the
drain line.
15. Construct the drain line routing it to an appropriate drain recep-
tacle abiding buy all local building and plumbing codes. DO
NOT construct drain line to elevations that exceed 4 feet above
the drain port of the control valve, exceed 20 feet in length, or
reduce the drain line diameter to smaller than that of the drain
line flow controller. For LCTA-100 series systems 1/2" inside
diameter plumbing is the minimum pipe size allowed for the
drain line. Install a plumbing union fitting in the drain line close to
the drain line flow controller. The drain line must be anchored to
the floor.
16. Connect the brine tank to the water softener’s control valve
brine port using the factory supplied fittings and tubing. See
pages 12-13 for Drain and Brine Connection Detail. The
brine tank should set on a common elevation as the mineral
tank and within distance so that it can be reached by the
length of factory supplied brine tubing. Add enough water
(6") to the brine tank so that water covers the top of the air
check. DO NOT add salt to the brine tank at this time.
17. Insert the meter cable’s sensor into the sensor port in the
meter according to Figure 2. Connect the plug end
of the meter cable wire into the P1 port of SXT controller
(See page 14 for location).
18. Connect the 24V transformer power supply wires to the
control valve controller. Connect wires into the P2PWR port
of SXT controller (See page 14 for location) .
19. If applicable, install a metal bonding strap across metal inlet
and outlet plumbing lines to maintain electrical continuity.
The system is now ready for Start Up.
