4.1
Hardness regulator:
=part number 9 on the illustration on page 1
Measure
the
hardness
of
incoming water by means of a
hardness test kit (not supplied
by Delta). Delta uses ppm
settings of CaCO
3
. (10 ppm
CaCO
3
= 1°fh) (1°dh = 1,78°fh)
Adjust the hardness regulator to
the
measured
value.
This
requires a hex key number 5.
4.2
Blending regulator:
= part number 8 on the illustration on page 1
With the blending regulator, you
can determine the outgoing
hardness. Depending on the
desired residual hardness, set
outgoing hardness with a hex key
number 5. The setting is
proportional, i.e. 1/10 – 1/5 –
1/… of total incoming hardness.
