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 electromechanical control panel.
2. Measure water hardness before/after appliance.
3. Check drain line from control valve; there shouldn’t be
any water flow (unless appliance is in regeneration).
4. Check drain line from brine cabinet overflow; there
shouldn’t be any water flow.
5. 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,...).

WATER CONDITIONER SALT

Picture 7
The appliance needs 'brine' for its periodic regenerations. This
brine solution is made from water, that is automatically dosed
in the brine cabinet by the brine float valve, and water
conditioner salt. The user should make sure that the brine
cabinet is always kept full of water conditioner salt. Therefore
he should periodically check the salt level inside the brine
cabinet and refill it if necessary. The salt lid can be removed
completely to facilitate refilling.
Ideally the level of water conditioner salt inside the brine
cabinet is kept between 1/3 and 2/3. A lower level of water
conditioner salt can cause insufficient brine saturation,
resulting in a loss of softening capacity. A higher level of water
conditioner salt can cause salt bridging (hard crust or salt
bridges in the brine cabinet). When you suspect salt bridging:

carefully pound on the outside of the brine cabinet to
break loose the salt bridges;

using a broom (or like blunt tool) carefully push the salt to
break it apart;
 pour warm water over the top of the salt to dissolve it.
APPEARANCE
To retain the appearance of the appliance, simply wipe it with
a damp cloth or clean it with a mild soap solution; never use
abrasive cleaners, ammonia or solvents.
RESIN CLEANER
Other contaminants (f.e. iron) present in the feed water can
cause the resin bed to foul up, resulting in a loss of softening
capacity. An approved resin cleaner can be used periodically
to thoroughly clean the resin bed.
SANITIZING THE APPLIANCE
This appliance is manufactured from premium quality
material and assembled in safe conditions to assure it is clean
and sanitary. If installed and serviced correctly, this appliance
will not infect or contaminate your water supply. However, as
in any 'device' plumbed-in in your water distribution system,
a proliferation of bacteria is possible, especially in case of
'stagnant water'. Therefore this appliance will automatically
rinse the resin bed periodically.
If the power supply to the appliance is disconnected for a
longer period of time, we recommend, when the power
supply is re-established, to manually initiate a complete
regeneration.
