BRINE CABINET
1.
Add water conditioner salt to the brine cabinet.
PRESSURIZING
2.
Make sure the bypass system is in 'bypass' position.
3. Make sure the semi-automatic timer of the water
softener is in service mode.
4. Open the mains water supply.
5. Open a cold treated water faucet nearby the water
softener and let the water run for a few minutes until all
air is purged and all foreign material that may have
resulted from the installation is washed out; close the tap.
6. Gently pressurize the water softener, by putting it into
service:
 factory bypass:
1.
open the 'outlet' valve;
2. slowly open the 'inlet' valve.
 3-valve bypass:
1.
close the 'bypass' valve;
2. open the 'outlet' valve;
3. slowly open the 'inlet' valve.
7. After 2-3 minutes, open a cold treated water faucet
nearby the water softener and let the water run for a few
minutes until all air is purged from the installation and the
resin bed is rinsed (it is normal for the rinse water to show
some discoloration!); close the tap.
8. Check the water softener and all hydraulic connections
for leaks.

After the first regenerations of the water softener, some
slight discoloration of the treated water might occur. This is
totally harmless and will disappear rapidly!
ADJUSTMENT RESIDUAL HARDNESS
WITH FACTORY BYPASS (optional)
Picture 6
9. Adjust the residual hardness of the water that leaves the
softener, by means of the adjusting screw, incorporated
in the ‘outlet’ valve of the factory bypass:

to raise the residual hardness: turn the screw counter
clockwise; usually 1 turn corresponds to a residual
hardness of ±4 °f (±2 °d), 2 turns to ±8 °f (±4 °d).

to reduce the residual hardness: turn the screw
clockwise.
PERFORM REGENERATION
Picture 7
10. Manually initiate a regeneration by turning the timer
knob clockwise until you feel the resistance of the drain
paddle being opened; typically this is at the '20' (minutes)
position; water will start flowing to the drain.
11. Turn the timer knob to the position that corresponds to
the recommended length of the regeneration cycle.
Recommended Length of Regeneration Cycle
Resin volume minutes
9 ltr (.3 Cuft) 45
12 ltr (.4 Cuft) 50
18 ltr (.6 Cuft) 75
26 ltr (.9 Cuft) 110
12.
Leave the timer in this position; while the control valve
performs the regeneration, the timer will count back and
automatically return to service position when the timer
knob has reached the 'OFF' position.
