Dial-a-Softness
Dial-a-Softness is a manual adjustment built into the con-
trol 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 Dial-a-Softness knob is set to the “SOFTEST” position (no
hard water bypass). See Figure 12.
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.
Letter on Dial-a-Softness Knob
1–3 gpg Hardness Bleed
SOFTEST
No Bleed
A
On between 20–30 gpg feed
B
On between 10–20 gpg feed
C
On less than 10 gpg feed
NOTE The HE 1.5 Twin must take into account the adjusted capacity if the Dial-a-Softness was changed. See
the GBE Programming for Commercial Softeners and Filters, except HF xN Manual (P/N 01027295) to
update the Dial-a-Softness setting.
Straight-Through Adapter
Shipped with each softener is a Culligan® straight-through adapter, which is used to connect the softener to the plumbing
system.
CAUTION! Close the inlet supply line and relieve the system pressure before cutting into the
plumbing! Flooding could result if not done!
Straight-Through Adapter Installation
Refer to
and the instructions below to connect the meter, straight-through adapter, and interconnecting pipe.
NOTE Use the same setup for both valves.
1. All HE 1.5 Twin units are equipped with a meter. The meter is installed on the outlet side of the control valve.
The meter body fits in the same space as the coupling between the control valve and the straight through adap-
ter. Make sure the arrow on the flow meter is pointing in the direction of the flow.
2. The straight-through adapter connects directly to the control valve with the meter and coupling and two assem-
bly pins. Lubricate all O-rings on the couplings/meter with silicone lubricant. See
3. Connect the interconnecting pipe. The interconnecting pipe is connected to the outlet of Control #1 and the inlet
of Control #2.
