WATER CONDITIONER SALT
Picture 11
Theapplianceneeds'brine'foritsperiodicregenerations.This
brinesolutionismadefromwater,thatisautomaticallydosed
in the brine cabinet by the control valve, and water
conditioner salt. The user should make sure that the brine
cabinetisalwayskeptfullofwaterconditionersalt.Therefore
he should periodically check the salt level inside the brine
cabinet and refill it if necessary. The salt lid can be removed
completely tofacilitate 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,
resultinginaloss ofsofteningcapacity.Ahigherlevelofwater
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;
usingabroom(orlikeblunttool)carefullypushthesaltto
break it apart;
pour warm water over the top of the salt to dissolve it.
APPEARANCE
Toretaintheappearanceof theappliance,simplywipeitwith
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 insafe conditions toassureit isclean
and sanitary. If installed andserviced correctly, thisappliance
willnotinfectorcontaminateyourwatersupply.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 is equipped with a
'days override' feature, that will automatically rinsethe resin
bed periodically, even in case of low or absence of water
usage.
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.
