1 | How to operate the control unit
The control unit regulates the operation of the deferrisation system.
1.1 How to set the time
The GENO-mat
FE-Z systems are factory-set in a way that the au-
tomatic regeneration is always released at 02:00 (at night). Upon
start-up or after a power failure, the current time must be set.
1. Loosen the screw at the housing cover (top right).
2. Open the housing cover.
3. Press and hold the red button (Fig. F-1, Item 6).
4. Turn the 24 hour disk until the reference arrow (Fig. F-1, Item 2)
points to the current time.
5. Release the red button (Fig. F-1, Item 6).
Note:
In case the preset time for the backwash (02:00) should be
unfavourable for internal reasons, set a time which deviates from the
current time at the 24 hour disk in order to adjust the starting time for
the backwash.
Example:
Desired starting time of the backwash: 22:00
Move clock forward 4 hours.
1.2 How to set the
backwash interval
The maximum backwash interval is 12 days. Furthermore, an auto-
matic backwash can be carried out after 6, 4, 3, 2 or 1 day(s) (fac-
tors of 12). Fig. F-1 indicates the setting for a backwash to be car-
ried out every 2 days.
1. Determination of the backwash interval.
For hygienic reasons, a backwash should be carried out every 6
days (factory-setting).
If the differential pressure of the filter is > 0.3 bar above normal
after 6 days due to a higher concentration of dirt in the water, a
backwash process should be initiated every 4 days or at even
shorter intervals.
The same applies in case of an early breakthrough of dirt parti-
cles.
