RECOMMENDATION
Notwithstanding the reliability of the appliance, we strongly
recommend to have it serviced and maintained on a regular
basis by a competent and duly trained technician. He will be
able to determine the appropriate maintenance interval for
the appliance, depending on your specific application and the
local operating conditions. The advantages of performing
regular maintenance are:
•
regular check of the local operating conditions (water
quality, pressure, etc);
•
regular control and adjustment of the settings of the
appliance, to guarantee it operates at maximum
efficiency;
•
minimize the risk of unexpected break-down.
Contact your dealer or installer for more information, or visit
our website.
ROUTINE CHECKS
Regularly the user should perform a basic check to verify if the
appliance is functioning correctly, on the basis of the
following control points:
1. Check settings of electronic control panel.
2. Check water composition before/after appliance.
3. Check drain line from control valve; there shouldn't be
any water flow (unless appliance is in regeneration).
4. Check appliance and surrounding area; there shouldn't be
any water leakages.
BYPASSING THE APPLIANCE
Occasionally it may be necessary to put the appliance
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
•
replenishment of filter media;
•
in case of an urgent technical problem;
•
when it is not necessary to supply treated water to the
application.

PF-AG1)

MAINTENANCE
The filter media inside this appliance consists of 'self-
sacrificing' minerals, that dissolve in the acidic water to raise
its pH to neutral level. In order to maintain the optimum
performance of the appliance, the filter media needs to be
replenished regularly. Ideally the level of filter media inside
the pressure tank is kept between 1/2 and 2/3 of the pressure
tank height. The frequency of replenishment depends on the
water usage and pH of the incoming water, but is typically
once or twice per year.

The user should make sure there is always a sufficient amount
of filter media in the pressure tank. Therefore he should
periodically check the level of filter media and refill it if
necessary. The easiest way to do this is by holding a bright
light against the semi-transparent pressure tank, so that the
top level of the filter media inside the pressure tank becomes
visible.
If the level of filter media has dropped below the minimum
level, the user should refill it.
1. Put the bypass system of the appliance in 'bypass'
position.
2. Manually initiate a regeneration, by pressing the scroll
button; the display will show:
Regen in 10 sec
3. Leave the appliance in this position; the countdown timer
will countdown to 0 sec and start a regeneration.
4. Wait until the drive motor has driven the control valve in
backwash position; the display will show:
Rgn: 10 Cyc1:
5. Wait for 10-15 sec for the pressure inside the appliance
to be relieved.
6. Unscrew the cap from the media fill opening on the
pressure tank.
7. Via the media fill opening, pour filter media in the
pressure tank as needed to reach the desired height.
8. Clean the threaded section of the media fill opening and
screw the cap back on.
9. Manually initiate a regeneration, by pressing the scroll
button; the display will show:
Regen in 10 sec
10. Put the bypass system of the appliance back in 'service'
position.
