7. Repairs
The
Watermanager GWM
contains components, which require inspections and maintenance works.
•
Inspections should be carried out by the operator of the system.
•
Maintenance and repairs should only be carried out by qualified specialists (see 1.9).
It is in the operator’s best interested to take note of the stated intervals for inspection and maintenance measures
and the described work steps.
If an inspection yields faults/damage in the
Watermanager GWM,
then you should contact your contracting party or DEHOUST.
To inspect the screen plate, the lid of the casing (secured by 4-6 wing screws) of the coarse filter is opened. Remove any stub-
born, coarse impurities, which could not be removed by the spray nozzles, from the screen plate using a cleaning brush. Dis-
pose of the filter residue in the residual waste.
Time frame: Quarterly
Check the solenoid valve to the backwash for impermeability and function. To do this, directly activate and disable the solenoid
valve in manual mode (see
Fehler! Verweisquelle konnte nicht gefunden werden.
) in the firmware set-up.
Time frame: Quarterly
Check the solenoid valve to the drinking water feed for impermeability and function. To do this, open the process water con-
sumer and wait until the fill level in the process water storage tank has fallen so that the solenoid valve is open. Reclose the
process water consumer and wait until the solenoid valve recloses.
Time frame: Quarterly
Check all hose connections ( air compressor, filtration) and drinking water and process water connections for damage, imper-
meability and porous or worn patches. If necessary, replace and reseal hoses/lines.
