Clack Valve Settings

Clack valve programming reference supplied for installer preparation. Original source: Honest Water Co. Confirm the actual unit, water hardness and household requirements before using any setting; Dallas examples are not DMV defaults.

Programming the valve

In order, start to finish

Set the clockStraight out of the box the display blinks. SET CLOCK, then up/down for the hours, NEXT, up/down for the minutes, NEXT.

HardnessHold NEXT + UP to reach hardness. In Dallas it is typically no more than 12, so set 12. Set this for the area and the house you are actually in - it is not a fixed number.

Regen dayOnce every 28 days. Again, adjust for the location and the household.

Regen time2:00 AM. That is also the factory default.

Capacity and saltHold NEXT + DOWN. It takes a moment, then shows softening. Press NEXT, set, NEXT again to reach capacity. Numbers are in the table below.

Finish outKeep pressing NEXT through the rest, leave everything else at normal, until you see C1. It then goes back on its own.

Kick off the regenTap REGEN and it shows regen today - it will run at 2 AM that night. Hold REGEN until it clicks over and it starts regenerating right now.

Capacity and salt, by system size

Teal is what Pete actually sets

System	Capacity range	Use	Salt range (lb)	Use
Standard	35 – 36	36	9.5 – 10	10
XL	about 45	45	about 12	12
Dual tank	about 48	48	about 12	12

These depend on the actual tank size you were shipped. If the tank does not match what you ordered, check before you program it.

Starting it up

The bypasses, in order

Bypasses go on hand tight, no more than hand tight.
They start closed when the regen begins and the valve is in backwash.
Crack them slowly and let the tank fill.
Once you see and hear water at the drain, open them all the way, slowly.
Then leave it alone and let it finish on its own.
