8.2.2 Periodical inspection
In addition to the daily checks, the activities described below
should be carried out at bimonthly intervals:
Check leakiness of wastewater connection on con-
trol valve
No wastewater to be detected on connection elbow
Check filter insert of fine filter in raw water pipe and
replace if contaminated or visible wear detectable
Check brine consumption during regeneration as
indicated by salt filling level change in brine tank.
Unsufficient salt consumption may indicate that brine sucking is
disordered. In this case the injector and injector screen cage
must be cleaned (see chapter „Minor maintenance“). Also,
check brine tube for leakiness.
8.2.3 Minor Maintenance
These works should be carried out every 6 months:
Exchange filter insert in raw water fine filter
Read and record water meter display
Determine raw water and soft water hardness
Use water hardness kit.
Check time-of-day and raw water setting on control
valve
In case of a deviation of more than 1°dH between the raw water
value measured and the value set, the control valve setting must
be corrected.
Clean injector and injector screen cage
For these works the injector cap(1) on he control valve must be
dismounted. Use the service spanner wrench (6) provided with
the device to loosen the screw connection
