Pre-Installation Considerations
(continued)
G. Pre Installation and Loading of Media
Systems that are 13" in diameter and larger are not loaded with
media. These systems must be loaded with media before placing
into service. To load a system follow the below steps.
1. Cap the top open end of the distributor tube with tape and
plastic sheeting to keep foreign debris from entering the
distributor tube. This cap must be secure and not come off
during media loading.
2. Place the distributor tube, screen end down, into the mineral
tank and center it in the bottom. The top of the distributor
tube should be flush with the top of the tank. If 4" x 2.5" tank
bushings are used, the distributor tube should be flush with the
top of the tank bushing.
3. Make sure the plastic and tape cap is secure to the top of the
distributor tube, place a funnel on the top of the tank and load
first the gravel (if different sizes of gravel are used load the largest
gravel first, then the smaller gravel) then the resin media into the
tank. The cap must not come off of the distributor tube during
the loading of the media.
4. Remove the plastic cap from the distributor tube. DO NOT
PULL UP ON THE DISTRIBUTOR TUBE when removing the
cap. The distributor tube top must remain flush with the top of
the tank.
5. Clean any media from the threads and top of the mineral tank.
6. Lubricate the O-rings on the bottom of the control valve
(distributor pilot O-ring and top of tank O-ring). Use non-
petroleum based silicone lubricant only.
7. Place the control valve on top of the tank. When doing this step,
seat the top of the distributor tube inside the centered O-ring
sealed port on the bottom of the valve first then press the valve
down until the tank threads come in contact with the valve
threads. This ensures that the distributor tube is properly seated
into the bottom of the control valve. Thread the valve on to the
tank clockwise. Be careful not to cross thread the valve or over
tighten it. A hand tight snug fit is appropriate for the control valve
torque. A wrench is not necessary. Do not use thread sealant or
PTFE tape on the valve base threads.
8. The system is now ready for installation. Follow the Installation
Section in the Installation, Operation and Maintenance Manual.
PWSRTA Twin Alternating Series Softeners
!
WARNING
Do not exceed water pressure of 120 psi (8.2 bar). Do not
exceed 110°F (43.3°C). Do not subject unit to freezing
conditions.
Installation Instructions
1. Turn off water heater(s).
2. Turn off the main water supply to the home and open an inside
faucet (cold and hot) to relieve any pressure within the plumbing
system.
3. Place the system in the desired installation location. Make sure
that the location is level and sturdy enough to support the weight
of the system once it is in operation.
4. Place the bypass valve in the bypass position.
5. Connect the cold water supply to the inlet of the water
conditioning system. While constructing the supply line, install a
master supply valve (user supplied) in the supply line and close it.
6. Connect the feed water line to the home to the outlet of the
system.
7. Plumb the drain line to an appropriate drain abiding by all local,
city, and state codes. Use a 3/4" drain line for backwash flow
rates of 7 gpm or for drain lines of 7 gpm and less that exceed
20' in length. Use a 1" drain line for backwash flow rates of 10
gpm and 12 gpm.
8. Connect the brine tank to the water softener control valve brine
inlet port using the factory supplied fittings and tubing. Add
enough water to the brine tank so that water covers the top of
the air check. DO NOT ADD SALT AT THIS TIME.
9. Open the user supplied feed water valve. Check for leaks and
repair as needed.
10. Allow the inside hot and cold faucet to remain open until all air
has been purged from the plumbing system. Then close the
faucet.
11. Locate Manual Regeneration Options in this manual to see the
steps to initiate an Immediate Manual Regeneration. Once you
have read that section place the system in backwash and unplug
the system from its electrical outlet once it has cycled into the
backwash position. This will stall the unit in backwash so all air
can be purged from one of the tanks.
12. Adjust the user supplied feed water valve to 1/4 open and place
the bypass valve into the service position.
13. Air will come out of the drain line until the backwashing tank is
completely purged of air. Then water will flow to drain. Allow
water to flow to drain for 15 minutes or until the water to drain is
clear of resin color throw.
14. Plug the system back into the electrical outlet and manually cycle
it through the remaining regeneration steps until it arrives in the
service position.
15. Repeat installation steps 11, 12, 13, and 14 of the General
Installation Instructions to purge the air from the second tank.
16. Check for leaks and repair as needed.
17. Installation is now complete and the system is ready for
programming and one cycle of brine tank refill so that the correct
amount of water is in the brine tank for the first regeneration
cycle. The brine tank refill must be done after programming the
system.
