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.
Check settings of electronic control panel.
2. Measure water hardness before/after water softener.
3. Check drain line from control valve; there shouldn’t be
any water flow (unless water softener is in regeneration).
4. Check drain line from brine tank overflow; there shouldn’t
be any water flow.
5. 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
This water softener needs 'brine' for its periodic
regenerations. This brine solution is made from water, that is
automatically dosed in the brine tank by the control valve,
and water conditioner salt. The user should make sure that
the brine tank is always kept full of water conditioner salt.
Therefore he should periodically check the salt level inside the
brine tank and refill it if necessary. Simply lift the brine tank
cover to check the salt level inside the brine tank.
Ideally the level of water conditioner salt inside the brine tank
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 tank). When you suspect salt bridging:
 carefully pound on the outside of the brine tank 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.
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'. therefore this water
softener is equipped with a 'days override' feature, that will
automatically rinse the resin bed periodically, even in case of
low or absence of water usage.
If the power supply to the water softener is disconnected for
a longer period of time, we recommend, when the power
supply is re-established, to manually initiate a complete
regeneration.

SERVICE VALVES
Picture 15
 = automatically operated = normally closed
 = manually operated = constantly open
The Normally Closed Service Valve in the outlet of each
Simplex system will only be opened when it is powered. To
manually open the Normally Closed Service Valve (f.e. in case
of a power failure), simply turn the white solenoid coil
counter clockwise.
