Setting; Commissioning - BWT A6X Instrucciones De Montaje Y Uso

At its first start-up, the device displays after a few seconds the message SERV, first step of the setting, which uses 5 keys:

The following steps are necessary and sufficient to set the softener.
You just need to know the hardness of the raw water (concentration in lime scale), measured before or known from the public water distribution network.
First press 3 seconds on the key M, until the message LANG appears on the display.

RINSING
The softener displays the message: REGE?
Press the OK key (once or 3 times, depending on
your model). REGE 1 is displayed and a complete
regeneration starts.
Progressively open the bypass tap => water
flows from the hydraulic block to the drain
through the evacuation tube. Let it flow in order
to fully rinse the softener.
Stop this rinsing by pressing OK during 5
seconds. Then SERV is displayed on the screen.
RESIDUAL HARDNESS SETTING
The hardness is measured in degrees (French °f
or German °dH degrees)
1°f = 10 milligrams of "lime scale" in one liter
of water
1°dH = 1.78 °f
• Activates the menu with a long press (5 seconds)
• Ongoing setting cancellation without record
• Down move within a list of choices
• Decrease / change of a parameter
• Up move within a list of choices

• Increase / change of a parameter
• Move from left to right digits (example: hours to minutes)
• Information on the salt level during filling
• Enter into a menu
• Setting validation
• A long press (5 seconds) triggers a manual regeneration. During this process, a brief press
forces the trigger of the next step.
Purpose
Change language if necessary
Language selection
Time setting : hours
Time setting: minutes
Specify the type of salt for some devices
Specify the resin volume within the softener, in liters.
Hardness unit choice:
°F or °dH
Enter the inlet hardness
(unit may be °dH)
Enter the outlet hardness
(unit may be °dH)
The hardness measurement is done with a kit
of reactive stripes or colored reactive liquid. See
further, in the chapter Routine maintenance.
It is possible to blend the softened water pro-
duced by the device with raw water, using a
blending unit located on the rear side of the
hydraulic block, in order to reach a residual
hardness of few degrees (value depending on
the country habits).
First, turn counterclockwise the knob (26) at
its maximum. Then screw the knob (27) until it
reaches its lowest level. Thus the outlet water
is fully softened (hardness =0°)
Then turn clockwise the knob (26) of half a
turn. The outlet water is then slightly blended
with raw water.
Slightly open any tap downstream from the
softener (or use the sampling tap of the bypass)
and measure the water hardness at this point.
Use the knob (26) to tune the hardness for low
consumption flow rates:
- Clockwise to increase it

How to do
to go to minutes
- Counterclockwise to reduce it
For hardness tuning at high flow rates, largely
open a tap downstream of the softener and
measure again the hardness.
Use this time the knob (27) to tune the hardness:
- Unscrew to increase it
- Screw to decrease it

NOTE: it is under the user's responsibility to
define the residual hardness compatible with the
equipment installed downstream of the softener.
