7.6 Residual Hardness Setting
1. 1.Simultaneously press the and buttons for
5 seconds.
2. Enter the calculated set value via the and
buttons.
3. Press the button three times to save the setting.
7.7 Manual Regeneration
1. Press the button for 5 seconds.
Manual regeneration starts immediately.
7.8 Blending Setting (Fig. 6)
After manual regeneration has been terminated, the
desired residual hardness (mixing ratio between raw
water and soft water) has to be set at the blending.
1. Open sampling point.
2. Setting blending.
Connect measuring device after the water softener.
Turn adjuster knob until the measuring device
shows the desired hardness (normally: 8,5°dH).
3. Close sampling point.
4. The water conditioning device is ready for
operation.
CAUTION!
If
is displayed, press no further
buttons (test mode manufacturer)!
Wait for approx. 10 seconds until the current
time is redisplayed!
i
Drinking water should have a residual hardness
of 1.4 mmol/l (equals 8 °dH)!
The sodium content of the softened drinking water
should not exceed the limit value of 200 mg/l!
Observe the reading examples!
i
Flushing takes place via the sewerage tube
during regeneration!
The total time required for all 4 regeneration
phases is:
• approx. 23.4 min/PW50-AS
• approx. 33.7 min/PW50-BS
• approx. 44.1 min/PW50-CS
CAUTION!
Do not overturn adjuster knob!
Position "max" Position "closed"
i
In position "closed" no untreated water added to
the soft water!
In position "max" untreated water added in
accordance with the nominal flow to the soft
water!
Reading Example

alkaline earths in the supply water
c

• Sodium concentration of the supply water
c
(Na

) = 50 mg/l
From the x-coordinate 5,3 mmol/m

to the point
of intersection with the

)-straight line for
c
(Na
+
) = 50 mg/l; transfer the value horizontally
onto the ordinate.

The residual hardness in the blended water
should be at least
