Note: Very important
1.
Always turn off the device if it has been repaired or maintained.
2.
When sending the device for inspection, make sure that the measuring
probes are always in a storage liquid when you send them. If the measuring
probes are dry for 3 to 4 hours, this may affect the following measurements
and lead to incorrect measurements.
HOW TO RINSE A DOSING UNIT
We take the extraction nipples from the acid and chlorine tank.
We put 2 buckets of lukewarm water in the place of the buses
Place the suction nipple in the buckets of water and run the dosing unit for half an hour, the
setting being such that the dosing pump system rotates.
After 30 minutes, remove the suction nipple from the water and let the dosing unit run for
another 5 minutes so that all the water is out of the hoses.
You can now safely ship your dosing unit
