1. Locate the softener tank and brine tank close to a drain where the system will be installed.
The surface should be clean and level.
2. Perform all plumbing according to local plumbing codes.
Use a 1/2” minimum pipe or tubing size for the drain line.
Use a 3/4” pipe or tubing for backwash flow rates that exceed 7 gpm or length that
exceeds 20ft (6m).
3. Only use Teflon tape on the drain fitting. Any solder joints near the valve must be done before
connecting any piping to the valve. Always leave at least 6” (152 mm) between the valve and
joints when soldering pipes that are connected to the valve. Failure to do this could cause
damage to the valve.
4. Cut the 1” central pipe flush with top of each tank.
5. Lubricate the o-ring on the bottom of valve that seals against the tank. Screw the valve on to
the tank. Be careful to not cross thread the valve into the tank. Only use silicone lubricant.
6. Add water until there is approximately 1” (25mm) of water above the grid plate. If the tank
does not have a grid, add water until it is above the air check in the brine tank. Do not add salt
to the brine tank at this time.
7. If the unit has a bypass valve, place it in the bypass position.
8. Slowly turn on the main water supply.
9. Open a cold soft water tap nearby and let water run a few minutes or until the system is free
of foreign material resulting from the plumbing work. Close the water tap when water runs
clean.
10. Place the bypass in the service position and let water flow into the mineral tank. When water
flow stops, slowly open a cold water tap nearby and let water run until air is purged from the
unit. Then close tap.
