WATER PRESSURE

The water must be between 2 bar and 7 bar. The water pressure must not drop below 2 bar as oth-
erwise the function can be impaired! If the water softener is not regularly regenerated, this can
result in a pressure loss and impairment of the softening function.
In the event of water pressure above 7 bar, a pressure reduction valve must be fit-
ted upstream of the water softener (see fig. 2). An operating pressure of over 7 bar
can lead to malfunction and failure.
In modern sanitary installations (in particular where single lever mixers are used), despite normal system
pressure conditions, peak pressures of up to over 30 bar frequently occur. This can cause damage to im-
portant functional interior parts of the controls. The optimum operating pressure for the water softener
lies between 3 bar and 5 bar. It works most economically under these pressure conditions.
For water pressures between 5 bar and 7 bar, the installation of a pressure reduc-
tion valve upstream of the water softener is recommended.
