Start Up Instructions - Watts LC-150 Series Manual

System Installation
7. 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.
8. Install an inlet water sample port in the supply line and close it.
9. If risk of vacuum exists, install Watts # 0556031 vacuum relief
valve in the supply line to protect the system against vacuum
damage.
10. 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 isola-
tion valve.
11. Install an outlet water sample port on the outlet water line of
the system and close it.
12. Install a bypass valve between the inlet and outlet plumbing
water lines and close it.
13. If not already factory installed on the control valve, attach the
drain line flow controller directly to the control valve's drain
port. See page 11 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.
14. 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, or reduce the drain line diam-
eter to smaller than that of the drain line flow controller. 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.
15. Connect the brine tank to the water softener's control valve
brine port using the factory supplied fittings and tubing. See
page 11 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.
16. Insert the meter cable's sensor into the sensor port in the
meter dome according to Figure 1. Connect the plug end
of the meter cable wire into the P1 port for SXT controller
(See page 14 for location) and P5 port for NXT2 controller
(See page 13 for location).
17. Connect the 24V transformer power supply wires to the
control valve controller. Connect wires into the P2PWR port
for SXT controller (See page 14 for location) and P14
port for NXT2 controller (See page 13 for location).
18. 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.

Start Up Instructions

1. Ensure all inlet and outlet isolation valves and the bypass
valves are in the closed position and the treated water faucet
hot and cold side are in the open position.
2. Open the main water supply valve to the building.
3. Check for leaks and repair as needed.
4. Plug the power cord of the control valve into an electrical
outlet to energize system.
5. Locate "Manually Initiating a Regeneration" in this manual
and follow the steps to place the system in the backwash
position. For SXT Controller reference page 26, for NXT2
Controller reference page 17.
6. Open the inlet isolation valve slightly until water can be heard
flowing through the isolation valve and allow the mineral tank
to fill with water. Air will come out of the drain line until the
mineral tank is full of water. Once water flow at the drain line
is observed, fully open the inlet valve and allow water flow
to drain for 10 minutes to flush the resin bed of any color. If
water at the drain shows any discoloration, continue to flush
the resin bed until water at the drain is clear.
7. After resin bed flushing is complete, plug the system back in
to the power outlet and return the control valve to the service
position by advancing through each step of regeneration
by pressing the extra cycle button. See Manually Initiating a
Regeneration for help.
8. Program the system according to the System Type following the
Control Valve Programming section of this manual. SXT Control
Valve Programming begins on page 25, NXT2 Control Valve
Programming begins on page 15.
9. Put the appropriate amount of water in the brine tank. This is
accomplished by manually cycling the control valve to cycle
step 4 "Brine Tank Refill" and allowing a complete brine tank
refill cycle to conclude.
10. Put the appropriate amount of salt in the brine tank. Do Not
fill the salt level past the brine well lid.
11. Fully open the outlet isolation valve.
12. Ensure the bypass valve is in the closed position.
13. Check for leaks and repair as needed.
14. Allow water to flow from the hot and cold side treated faucet
until all air has been purged from the plumbing system. Then
close both the hot and cold side treated water faucet.
15. Turn on water heaters.
Start up is now complete and the system is ready for operation.
