How do I bring my dosing device in for maintenance or repair?
Keep in mind that when you remove the suction nipples from the acid and chlorine
container there is still a certain amount of liquid in the suction tube and pump.
The easiest way to rinse the suction and pump is just to hang the removed suction nipples in
a bucket of water instead of the barrels and let the installation run for 30 minutes. Now the
unit is rinsed and ready to be disconnected. Now it can be transported in a safe way without
causing any damage to your means of transport.
At delivery the measuring probes are in a container with storage liquid. Always keep the
probes in the storage solution during transport. If the probes are transported DRY, there is a
great risk that they will be damaged on arrival and no longer measure correctly, and
therefore they are out of warranty.
A device can only come in for repair after the application of a repair number, no devices will
be accepted without a repair number. The repair number can be printed out and is stuck on
the appliance.
