10.4 CHANGING THE RESINS
The resins’ softening capacity ends after 5-7 years. This pe-
riod can change based on the characteristic of the feed water
and the quantity of softened water.
After this period of time, the user needs to decide if it is enou-
gh to change the resins or if it is better to change the water
softener itself.
To change the resins it is necessary to disconnect the water
softener as described in the previous chapter.
Bring the tank to an appropriate place to change the resins
and clean the interior of the tank.
Unscrew the valve from the tank, being careful not to lose the
o-ring of the valve.
Do not throw the resins in the domestic discharge.
The resins are not biodegradable and must be considered a
non-hazardous waste (code CER 190905).
After changing the resins, check and clean the valve seal from
any resin residue. Change the o-ring if necessary.
Insert the o-ring back in its place and tighten the valve to the
tank.
Re-connect the water softener and activate it (see chapter 4,
“ACTIVATION”) Check that there are no leakage.
11) MAINTENANCE FOR THE USER
Maintenance for the user only consists in refilling the brine
periodically with sodium chloride (NaCl, common salt) (fig. 8).
If salt is lacking, the water softener will not be able to soften
the water.
Caution
: Use refined salt for cooking, even in tablets, suitable
for water softeners.
Keep the brine tank cap closed, to avoid that dust or other
substances may fall inside and compromise the equipment
and the water.
The user is responsible for refilling the brine tank with
salt, so we suggest checking the salt levels in the con-
tainer periodically.
Use a container to insert salt, to avoid propping the salt
package on the brine tank.
12) MISUSE OF THE EQUIPMENT
This equipment has been created to soften drinking water for
domestic and technological use. The equipment must not be
used for any other purpose and it must not be modified or
tampered with in any way.
Any other use than the one specified in this manual is impro-
per and therefore dangerous. The manufacturer cannot be
considered responsible for any damage caused by improper,
mistaken or illogical use of the equipment.
• It is forbidden to feed the equipment with any liquid other
than drinking water.
• It is forbidden to put any products other than cooking salt
(NaCl) and water in the salt container.
13) EQUIPMENT DISPOSAL
Any waste must be disposed according to the applicable nor-
ms.
The water softener is built with non-hazardous materials like
polymers and parts in stainless steel they must be disposed
according to the applicable norms.
Do not throw the resins in the sewer.
The resins are not biodegradable. They are classified as
non-hazardous waste, and must be disposed accordingly (co-
de CER 190905).
14) USEFUL INFORMATION
Experience teaches that often malfunctioning of water softe-
ners is caused by an incorrect outlet pipe installation (fig.
4, A). For this reason, we advise you to perform a correct
installation (fig. 3, F), using the outlet pipe provided. Where
possible, it is advisable to install a filter before the water softe-
ner to get rid of substances that could compromise the good
functioning of the fixture (fig.15).
