13. Once in 2C cycle (brine draw) check if the brine is effectively drawn by the valve, and advance to

Sanitization
7.2.1. Disinfection of water softeners
The construction materials used in modern water softeners do not support bacterial growth, nor will
these materials contaminate a water supply. During normal use, a softener may become fouled with
organic matter, or in some cases with bacteria from the water supply. This may result in an off-taste
or odour 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 from 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
accordingly.
Dosage
Polystyrene resin: set 1.25 mL fluid per 1 L of resin.
Non-resinous exchangers: set 0.85 mL fluid per 1 L.
Brine tank softeners
Backwash the softener and add the required amount of hypochlorite solution to the well of the brine
tank. The brine tank should have water in it to permit the solution to be carried into the softener.
Proceed with the normal regeneration.
Calcium hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in several forms including tablets and
granules. These solid materials may be used directly without dissolving before use.
Dosage
Measure two grains ~ 0.11 mL 1 L.
Brine tank softeners
Backwash the softener and add the required amount of hypochlorite to the well of the brine tank. The
brine tank should have water in it to permit the chlorine solution from being carried into the softener.
Proceed with the normal regeneration.
