Incorrect chemical concentration*/ No suction of chemicals
Below is a checklist to go through to identify the problem you are having and how to solve it. Some of the points are obvious but still relevant. If you need instructions on how to perform the service, please go to our TrainingTube® platform where we have collected a wide range of video tutorials.
*Always consult your chemical supplier before making any adjustments of the concentration, or if you are unsure of the correct concentration. Application of chemicals with an incorrect concentration will impact their efficiency, and the surfaces will not be properly sanitized.
1. Check if the dosing valve is adjusted correctly
If not, and if you know the correct settings, adjust the dosing valve. You can find video tutorials on adjustment of the various types of dosing valves on our TrainingTube® platform.
2. If you are using fixed dosing, check that you are using the correct chemical limiter
If not, replace it with the correct one.
3. Check if the chemical limiter is clogged
If yes, clean or replace the limiter.
4. Check if the suction filter at the end of the suction hose is clogged
If yes, clean or replace the suction filter.
5. Check if the dosing valve is clogged
If a click-dosing valve is clogged, it must be replaced. If it is a needle valve, it must be cleaned or replaced.
6. Check if the non-return valve on the dosing valve is clogged
If yes, clean or replace the non-return valve. If the non-return valve is clogged, the dosing valve will be clogged as well and in need of replacement og cleaning (see no. 5).
7. If applying a central chemical pump station
check the manometer on the water inlet and make sure the pressure is 3 – 3,5 bar.
8. Check that the hole in the foam/disinfection nozzle is not blocked
by chemical residues, and clean or replace if necessary.
9. Check for leaks on the chemical inlet
(from the injector to the suction hose) that may lead to false air being sucked into the system. False air prevents the injector from creating the vacuum that sucks up the chemicals.
10. Check for water leaking from the suction hose
If this is the case, the non-return valve is malfunctioning. Clean or replace if necessary.
