ROUTINE CHECKS
Regularly the user should perform a basic check to verify if the
water softener is functioning correctly, on the basis of the
following control points:
1.
Measure water hardness before/after water softener.
2. Check drain line from control valve; there shouldn’t be
any water flow (unless water softener is in regeneration).
3. Check drain line from cabinet overflow; there shouldn’t
be any water flow.
4. Check water softener and surrounding area; there
shouldn’t be any water leakages.
BYPASSING THE WATER SOFTENER
Occasionally it may be necessary to put the water softener
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
application.

WATER CONDITIONER SALT
Picture 11
The water softener 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.
BRINE CABINET
To retain the appearance of the water softener, 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 WATER SOFTENER
This water softener is manufactured from premium quality
material and assembled in safe conditions to assure it is clean
and sanitary. If installed and serviced correctly, this water
softener 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'.
We recommend to perform a regeneration regularly,
especially in case of longer periods of time with low or
absence of water usage.
