General Residential Installation Check List

Water Pressure

A minimum of 25 lbs of water pressure is required for regeneration valve to operate effectively.

Electrical Facilities

An uninterrupted alternating current (A/C) supply is required. Please make sure voltage supply is compatible with unit
before installation.

Existing Plumbing

Condition of existing plumbing should be free from lime and iron buildup. Replace piping that has heavy lime and/or iron
build-up. If piping is clogged with iron, install a separate iron filter unit ahead of the water softener.

Location of Softener and Drain

Locate the softener close to a clean working drain and connect according to local plumbing codes.

Bypass Valves

Always provide for the installation of a bypass valve if unit is not equipped with one.

CAUTION

• Do not exceed 120 psi water pressure.

• Do not exceed 110°F water temperature.

• Do not subject unit to freezing conditions.

Valve Installation and Start-up Procedures

1. Place the softener tank where you want to install the unit.

NOTE: Be sure the tank is level and on a firm base.

2. During cold weather it is recommended that the installer warm the valve to room temperature before operating.

3. Perform all plumbing according to local plumbing codes.

— Use a 1/2" minimum pipe size for the drain.

— Use a 3/4" drain line for backwash flow rates that exceed 7 gpm or length that exceeds 20′ (6 m).

4. Cut the 1" distributor tube (1.050 O.D.) flush with top of each tank.

NOTE: Only use silicone lubricant.

5. Lubricate the distributor o-ring seal and tank o

6. Solder joints near the drain must be done before connecting the Drain Line Flow Control fitting (DLFC). Leave at least 6"
(152 mm) between the DLFC and solder joints when soldering pipes that are connected on the DLFC. Failure to do this
could cause interior damage to DLFC.

7. Use only Tef lon tape on the drain fitting.

8. Be sure the floor under the salt storage tank is clean and level.

9. Place approximately 1" (25 mm) of water above the grid plate. If a grid is not utilized, fill to the top of the air check in the
salt tank. Do not add salt to the brine tank at this time.

10. On units with a bypass, place in Bypass position.

— Turn on the main water supply.

— Open a cold soft water tap nearby and let water run a few minutes or until the system is free of foreign material

(usually solder) resulting from the installation. Close the water tap when water runs clean.

11. 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.

12. Plug the valve into an approved power source. When the valve has power it drives to the In Service position.

Control Start-Up Procedures (Cont’d.)

Final Setup

With proper valve operation verified:

1. Add water to the top of the air check. Manually step the valve to the Brine Draw position and allow the valve to draw
water from the brine tank until it stops.

NOTE: The air check will check at approximately the midpoint of the screened intake area.

2. Manually step the valve to the Brine Refill position and allow the valve to return to the In Service position automatically.

3. With the valve in the Service position, check that there is approximately 1" (25 mm) of water above the grid in the brine
tank, if used.

4. Fill the brine tank with salt.

5. Setup is complete, the control can now run automatically.

Control Operation

Immediate Regeneration Valves with Days Between Regeneration Override Set

When the valve reaches its set Days Since Regeneration Override value, a regeneration cycle initiates immediately. This
event occurs regardless of the Volume Remaining display having reached zero gallons.

Delayed Regeneration Valves With Days Between Regeneration Override Set

When the valve reaches its set Days Since Regeneration Override value a regeneration cycle initiates at the preset
Regeneration Time. This event occurs regardless of the Volume Remaining display having reached zero gallons.

Control Operation During Regeneration

In Regeneration the control displays a special Regeneration display. In this display the control shows the current
regeneration step number the valve is advancing to, or has reached, and the time remaining in that step. The step number that
displays flashes until the valve completes driving to this regeneration step position. Once all regeneration steps are complete
the valve returns to In Service and resumes normal operation.

Less than 6 minutes
remaining in
Regeneration, Step 1

Figure 7: Regeneration Display

Pushing the Extra Cycle button during a Regeneration cycle immediately advances the valve to the next cycle step position
and resumes normal step timing.

Control Operation During Programming

The control only enters the Program Mode with the valve In Service. While in the Program Mode the control continues to
operate normally monitoring water usage and keeps all displays up to date. Control programming is stored in memory
permanently. There is no need for battery backup power.

Control Operation During A Power Failure

During a power failure all control displays and programming are stored for use upon power re-application. The control retains
these values for years, if necessary, without loss. The control is fully inoperative and any calls for regeneration are delayed.
The control, upon power re-application, resume normal operation from the point that it was interrupted. An indication that a
power outage has occurred is an inaccurate Time Of Day display.
