• the controller sends commands to the motor for camshaft movement. However, water
pressure/flow are required during the regeneration cycle for backwash, purge and refill, and
brine draw to actually take place;

6.2 Cleaning, disinfection and sanitization
The construction materials of the modern water softener will 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. In this case, the tank of the softener must be cleaned and
disinfected.
Some softeners may need to be disinfected after installation and some softeners will require
periodic disinfection during their normal lifetime.
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.
6.2.1 Cleaning of softeners
Make sure the brine tanks remains free from debris, waste, scraps that could be drown in the
valve during brine draw cycles of regenerations. Make sure the softener and its parts remains
clean to ensure proper function. Note that camshaft positioning is made by a optical sensor.
Should this optical sensor be obstructed, malfunctions may happen.
6.2.2 Disinfection with sodium or calcium hypochlorite
These materials are satisfactory for use with polystyrene resins, synthetic gel zeolite, greensand
and bentonites.
6.2.2.1 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 per liter of resin.
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.
6.2.2.2 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.
