9.7.1 Result file
The result file is in .txt format and structured as follows:
10. Maintenance
10.1 Cleaning
The following components of the DID require periodical checks
and cleaning, the interval depends on the quality of the water in
which they are used. We suggest to check these components on
a monthly basis.
10.1.1 Inlet strainer
The strainer includes a filter that collects coarse material and can
foul. Therefore, a periodical check of the strainer is necessary.
We recommend to clean the filter in the following intervals:
• monthly
• if the flow drops, although all valves are open, the pump (if
installed) is working properly and the inlet pressure is suitable.
Cleaning the inlet strainer
1. Turn off the water flow.
2. Unscrew the cap from the strainer.
3. Remove the filter.
4. Rinse the filter with drinking water.
5. Remove any coarse materials from the strainer housing.
6. Reinsert the filter.
7. Screw the cap back onto the strainer.
10.1.2 Flow detector
The flow detector contains inner parts that can be affected by
fouling. It case the flow detector does not respond to flow
changes, it can be dismantled from the DID and carefully cleaned
with water and a soft brush.
Dismantling the flow detector
1. Turn off the water flow.
2. Disconnect the CU 382 control unit from the power supply.
3. Unscrew the hose connection.
4. Remove the hose.
5. Disconnect the wires of the flow detector from the CU 382.
6. Unscrew the flow detector.
7. Clean the flow detector carefully with water and a soft brush.
8. Screw in the flow detector back.
9. Reconnect the wires of the flow detector to the CU 382.
10. Refit the hose.
11. Screw on the hose connection.
10.1.3 Sensor
See the manual "Sensors V1" supplied with the sensor.
10.1.4 Control unit CU 382
If necessary, clean the surfaces of the CU 382 control unit with a
damp and clean cloth.
