Sanitization; Disinfection Of Water Softeners; Sodium Or Calcium Hypochlorite - Pentair Siata V132 SFE Installer Manual

11. Fill the brine tank with salt. It is possible to mark the level of water in the brine tank when it is
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 an irregularity during regeneration that may lead to
softener inefficiency.
12. With the brine tank completely refilled and full of salt, adjust the safety brine float in the brine
well to the water level, use the mark done on step #5 as a reference. Make sure the overflow
elbow is installed above the float level.
13. Open the inlet manual valve and check there is no refill anymore and the safety brine valve
floater has successfully closed the brine line.
14. Open the outlet manual valve. And a faucet downstream the softener. Softener is now in service
and fully operating.
15. After the softener have been running a few minutes in service cycle, proceed to hardness test on
the outlet water to make sure the water is treated.
A
Note
This procedure is intended for system using a salt platform in the brine tank. Not using a
salt platform may result in salt consumption discrepancies and softener loss of efficiency.

Sanitization

7.2.1. Disinfection of water softeners

The construction materials used in modern water conditioners do not support bacterial growth, nor
will these materials contaminate a water supply. During normal use, a conditioner 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 conditioner may need to be disinfected after installation. Some conditioners will require
periodic disinfection during their normal life. Consult your installing dealer for more information on
disinfecting your conditioner.
Depending on the conditions of use, the conditioner 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 35.5 mL fluid (1.2 ounce) per 28.3 L (1 cubic foot) of resin.
Non-resinous exchangers: set 23.7 mL fluid (0.8 ounce) per 28.3 L (1 cubic foot).
