INSTALLATION PROCEDURES
STEP 1 – CONNECT TO WATER SUPPLY
A. Prepare the water softener valve for installation.
1. Remove the two red H-clips from the control valve to allow installation of the bypass valve.
Use a small screwdriver to pry the H clips up and off the valve.
2. Apply non-petroleum silicone lubricant to the two connection ends on the bypass valve.
3. Push the bypass assembly into the control valve.
4. Install the two red plastic H-clips from the top of the bypass valve. Push the H-clips all the
way down until they snap into place.
5. The brass connectors should already be installed in the bypass valve. If they are not, push the
two brass connectors in place into the bypass valve and install the two H-clips.
6. Put the bypass valve into the bypass position by turning both sides of the valve to the bypass
position as shown on top of the bypass valve.
Note : The valve comes with two extra red H-clips and one extra gray clip for the brine line
connector.
B. Prepare the softener loop for installation.
1. Shut off the main water supply to the house.
2. Open the hose bib to relieve pressure and drain out excess water.
3. Place a bucket or the softener brine tank under the softener loop to catch the excess water that
will spill out when you cut the pipe.
4. Cut the plumbing loop off.
5. Determine the inlet side of the loop by turning the main water on very slightly until water
comes out of one of the sides of the loop. This is the inlet supply. Warning: You must
connect the incoming side of the softener/conditioner to the inlet supply from the loop.
Failure to connect with the proper directional flow can damage the water softener/conditioner
and your household plumbing.
