water softener

15) USEFUL ADVICE

Experience teaches that, often, malfunctioning of water softe-
ners is caused by an incorrect outlet pipe installation (fig. 4,
A). For this reason, we advise you to perform a correct instal-
lation (fig. 3, F), using the outlet pipe provided.
Where possible, it is advisable to install a filter before the
water softener to get rid of substances that could compromise
the good functioning of the fixture.
PROBLEM
The valve does not regenerate automatically
The valve regenerates at the wrong time
Brine is not sucked
The brine tank fills too much
Water softener salt consumption is higher or
lower than expected
After regeneration, water is not softened

- make sure that the fixture is connected to power supply (fig. 6, G)
- check the settings (see "9 Setting the timer")
- check the current time and regeneration time settings (see "9 Setting the timer")
- make sure network pressure is at least 2 bar
- make sure the unloading pipe isn't blocked and doesn't have too narrow elbows
flattening the pipe (fig. 4, A)
- clean the injector (fig. 6, B) (see "14 Maintenance")
- make sure the valve ins't sucking air where there are the quick connections (fig. 6, A)
- make sure the unloading pipe is not blocked and does not have too narrow elbows
flattening the pipe (fig. 4, A)
- make sure the valve is not sucking air where there are the quick connections (fig. 6,A)
- clean the injector (fig. 6, B) (see "14 Maintenance")
- make sure the working pressure is at least 2 bar
- check if the "salt amount" value is set to "L"
(see "9.6 Measuring out salt for regeneration")
- check if the "salt amount" value is set to "L"
(see "9.6 Measuring out salt for regeneration")
- check the valve settings (see "9 Setting the timer") (See 9.5 Setting regeneration day)
- check the power supply and the valve settings
- check the presence of salt in the brine tank (fig. 7)
- check the correct screwing of the mixer screw (fig.2, A-2 ,B)
"The program can't work anymore". Press the button h to reset. If the error signal does not
disappear, replace the control.
Unplug and re-plug in the fixture. If the error does not disappear, it means that the power
supply frequency is not 50 or 60 Hz, or the timer is out of order.
"The control can't get any signal from the cam shaft"
Wait for the cam shaft to reach the "service position", and the error signal will disappear.
If the error signal does not disappear and the cam shaft keeps rotating, check that the
connecting cable between the engine and the control are not damaged (fig. 6, H), and that
the optical sensor is the right place (fig. 6, E).
