3.5 Softener's available options
3.5.1 Chlorine generator and check salt led
The Evolio 255 controller has the capability to produce a low level of chlorine to chlorinate the
resin bed during regeneration. A check salt light will indicate when the user needs to add salt to
the brine tank. Potassium chloride or sodium chloride may be used.
1. Unplug the wall-mounted transformer.
2. Shut off water supply or put bypass valve(s) into bypass position.
3. Relieve system pressure before performing any operations.
4. Remove the softener’s and valve’s covers, see Covers removal (softener and valve)
[ → Page 62].
5. Remove the existing refill controller (1) with the ball (2) from the valve and replace it with the
one (3) provided in the kit (P/N 1244336).
6. Connect the end of the cable (P/N 1206065) to the refill controller previously installed.
Connect firmly to ensure a good contact.
7. Reverse above procedure steps to rebuild.
CAUTION
No programming is necessary for the chlorine generator to work properly on the
controller.
The system will be automatically functional after the chlorine generation senses brine for
the first time. There is a check salt light on the front of the controller that will switch ON
when there is no brine present during the brine draw.
