4.1
Hardness regulator:
=part number 9 on the illustration on page 2.
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 2.
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.
