N Fill the brine tank or cabinet with salt. You may want to mark the level of water in the brine tank/
cabinet when completely refilled with water and full of salt. In the future, after each
regeneration, you can visually control that the quantity of water refilled should be between the 2
marks done. Marking are optional, but may allow to visually detect any irregularity during
regeneration that may lead to softener inefficiency.

Sanitization

7.2.1. Disinfection of water softeners

The materials of construction of the modern water softener will not support bacterial growth, nor will
these materials contaminate a water supply. In addition, during normal use, a softener may become
polluted with organic matter, or in some cases with bacteria from the water supply. This may result
in an off-taste or odor in the water.
Thus, your softener may need to be disinfected after installation. Some softeners will require periodic
disinfection during their normal lifetime. Consult your installing dealer for more information on
disinfecting your softener.
Depending on the conditions of use, the softener type, the type of ion exchanger, and the disinfectant
available, a choice can be made among the following methods.

7.2.2. Sodium or calcium hypochlorite

These materials are satisfactory for use with polystyrene resins, synthetic gel zeolite, greensand and
bentonites.
5.25% Sodium hypochlorite
If stronger solutions are used, such as those sold for commercial laundries, adjust the dosage
