Plumbing Connections - Culligan 9" Owner's Manual

Dial-a-Softness
Dial-a-Softness is a manual adjustment built into
the control valve that allows for variable hardness
bypass into the softened water. The hard water
bypass can be adjusted to produce 1–3 gpg
hardness bleed. Shipped from the factory the Di-
al-a-Softness knob is set to the "SOFTEST" position
(no hard water bypass). See Figure 13.
To set the Dial-a-Softness:
1. Locate the Dial-a-Softness knob on the
control valve.
2. Set the Dial-a-Softness knob to position
A, B, or C as outlined in the table
below, based on raw water hardness; this should produce a 1–3 gpg hardness bleed.

NOTE The HE must take into account the adjusted capacity if the Dial-a-Softness was
changed. See Advanced System Setup to update the Dial-a-Softness setting.

Shipped with each softener is a Culligan
plumbing system. The bypass allows the softener to be isolated from the water service line if service is
necessary while still providing water to the home. The bypass valve can be directly plumbed into the
system, or can be connected with the following optional sweat connection kits.
