POWER FAILURE
In the event of a power failure, the settings will remain
unchanged, but the electromechanical clock will stop
working; consequently the time of day will not be maintained
and will need to be set again.
When the power failure occurs during the execution of an
automatic regeneration, the control valve will remain in the
regeneration position; when the power supply is re-
established, the control valve will resume the regeneration
from the point where it was interrupted.
SERVICE MODE
In service mode the drain plunger (G) will be closed. The
actuator (F) should NOT be visible.
REGENERATION MODE
In regeneration mode the drain plunger (G) will be pushed
down by the actuator (F). The actuator (F) will be visible.
The control valve can be reset to service mode at any time by
slowly turning the timer knob (H) counter clockwise until the
drain plunger (G) is released again by the actuator (F).
MANUAL REGENERATION
It is possible to manually initiate a regeneration:
1. Push in the skipper tab (E) that is aligned with the day
indicator (C).
2. Turn the timer knob (H) counter clockwise, until the time
in the time of day window (I) equals the time in the time
of regeneration window (B).
3. The time of day and the skipper tab (E) must be reset,
when the regeneration is terminated.

PROGRAMMING INSTRUCTIONS
Before starting the programming, make sure that the control
valve is in the service mode.
1. TIME OF REGENERATION:
Turn the clock plate (A) until the desired time of

regeneration appears in the time of regeneration
window (B).
2. TIME OF DAY:
Turn the timer knob (H) counter clockwise until the

correct time of day appears in the time of day window
(I).
3. DAYS OF REGENERATION:

The regeneration frequency needs to be set in function
of:
- the exchange capacity of the water softener (= litres of
resin),
- the water hardness,
- the water usage.

We recommend a regeneration frequency of min. 1x
regeneration per week.
The regeneration frequency, i.e. the number of days in service
after which the water softener needs to be regenerated, must
be calculated, by dividing the nominal exchange capacity of
the water softener by:
1. the local water hardness,
2. the peak daily water usage.
Nominal Exchange Capacity
Resin volume m³x°f
9 ltr (.3 Cuft) 32
12 ltr (.4 Cuft) 48
18 ltr (.6 Cuft) 81
26 ltr (.9 Cuft) 117
Example:
12 ltr resin

Water hardness = 25 °f

Peak daily water usage = 800 ltr/day = 0,8 m³/day

 Regen freq. = nominal
water hardn. x daily water usage
= 48
25 °f x 0,8 m³/day
= 2,4 days
 Regeneration every 2 days
To set the days at which a regeneration must take place:
With all skipper tabs (E) pulled out, rotate the skipper

wheel (D) until day "1" is aligned with the day
indicator (C);
push in skipper tabs (E) which correspond with the

desired days of regeneration.
