10.1  Maintenance

Interval

Maintenance work

Regularly

Check whether the correct flow value is displayed.
If this is not the case, recalibrate the flow - see chapter "calibrate".

If stroke feedback is used: Adjust the stroke length with the metering pump run‐

ning and set just above the programmed upper limit - the flow identifier at the

pump should no longer flash.
Adjust the stroke length with the metering pump running and set just below the

programmed lower limit - the flow identifier at the pump should no longer flash.
If this is not the case, check for the cause and as necessary readjust the Dulco‐

Flow

®

 - see 

Ä

 Chapter 8.4.3.1 „Calibrate "stroke feedback"“ on page 29

If stroke feedback is used: Check whether the stroke feedback LED (right-hand

side of the device) illuminates in time with the strokes.
If this is not the case, check for the cause and rectify as necessary.

Check whether feed chemical is coming out.

If necessary, carefully wipe the device with a soft cloth and soapy water.

10.2  Repairs

Only ProMinent of customer service authorised

by ProMinent may repair the DulcoFlow

®

 flow

meter.
