7.2 Regulation of residual hardness
As stated out in section 2.7. it is recommended not to supply
completely softened water to household installations.
Denver systems have a residual hardness regulator that allows
to adjust the hardness quantity in the treated water.
This works making a small test of non treated water with a
completely softened water.
In order to regulate the residual hardness you should carefully
open the regulator.
Now you can test the hardness of the outlet water and check
that it is according to the desired values. If it is not like this
adjust the regulator and check it again.
ATENTION:
The hardness regulator is supplied comple-
tely closed, so if you do not regulate it the softener will
provide a totally softened water.
