1. Service (maintenance) activities

Operation of the water softener is
entirely automatic.
Basic maintenance activities for which
the user of the water softener is
responsible, include:
 control of salt level in the brine
 periodical refill of regeneration salt
 control of hardness of water
 control of water pressure in the
A. Refilling salt in brine tank
B. Salt bridges (concrements)
A hard crust or salt bridge is caused
by increased humidity within the
water softener installation site. It can

if low salt level needs to be topped
up
treated by the water softener -
once every week
installation (control of installed
pressure gauges) - once every
fortnight
The salt level control device will indicate the need to
refill salt. Check periodically (recommended once every
week) if the tank needs to be refilled with salt. Refill the
tank with salt each time when the indicator shows level
"2". Refilling the tank with salt is considered to be a
service (maintenance) activity . In case when the brine
tank is empty (no regeneration salt), the ion exchange
resin will not regenerate and as a result the water
softener will not soften water. Make sure to set the
actual salt level each time the brine tank is refilled with
salt.
If possible refill regeneration salt by entire packaging
(25 kg packaging). When refilling regeneration salt
make sure to prevent any contaminants from
penetrating into the brine tank. In case the brine tank is
contaminated, rinse the tank with clean water. Also
make sure that there are not regeneration salt tablets in
the brine valve well. In order to prevent any tablets from
getting into the brine valve well, refill the brine tank with
tablets only if the well is covered with purposely
provided cover..
 control of purity of filter screen of
the preliminary filter, periodical
replacement of the filter screen
and / or control of pressure
upstream and downstream of the
preliminary filter - once every
week or every fortnight
 control of clock indications in
terms of current hour and possible
resetting of clock indications
(resetting time - see above).

Important notice!
Due to specific requirements for
quality of the regeneration agent only
regeneration salt approved by the
water softener manufacturer should
be used (regeneration salt in tablets

the PN 973 norm).
