Maintenance - Maxima MAX-OXY Instructions D'installation & Emploi

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.:
in case of an urgent technical problem;

when it is not necessary to supply treated water to the

house/application (refill swimming pool, irrigation,...).

Other contaminants (f.e. suspended solids or organic matter)
present in the water can cause the filter media to get:
prematurely

backwashing and loss of filtration capacity,
fouled, resulting in a loss of oxidizing capacity.

In case of premature clogging of the filter media, the filter
media must be backwashed 'aggressively'.
1. If possible, increase the inlet pressure.
2. Remove the backwash flow control from the drain outlet
of the control valve.
3. Manually initiate a regeneration, by pressing the scroll
button; the display will show:
Regen in 10 sec
4. Leave the appliance in this position; the count-down
timer will count down to 0 sec and start a regeneration.
5. As soon as the control valve has reached cycle 1 (=
backwash cycle), unplug the transformer from the
electrical outlet.
6. Leave the appliance in the backwash position for at least
20 min, to thoroughly backwash the filter media.
7. Plug the transformer back into an electrical outlet; the
control valve will return to the service position, stay there
for 60 sec. and restart a complete regeneration from the
beginning.

We strongly recommend to lower the regeneration
interval to prevent premature clogging of the filter media in
the future.
In case of fouling of the filter media, the filter media should
be regenerated using an oxidizing agent, such as potassium
permanganate (KMnO
