on Initial Commissioning
Since an anti-corrosion agent is added in the final inspection stage for quality assurance
purposes, the machine may still contain traces of residue. Therefore, carry out the following
steps to ensure uninterrupted operation and a long service life.
1. Remove the water filler screw
2. Fill with clean water until the pump is full
3. Screw in the water filler screw
4. Open the pressure line (water tap)
5. Switch on the pump and allow it to run for approx. 1 min
6. Switch off the pump and disconnect the mains plug
7. Open the water filler and drain screw and allow the remaining water to drain
out via the water drain screw
8. Screw in the water drain screw
9. Fill with clean water until the pump is full
10. Screw in the water filler screw
11. Slightly open the pressure line (water tap)
12. Connect the mains plug and switch on the pump
13. Repeat the steps again, if required
Failure to observe these technical instructions may lead to foaming in the machine. This
prevents the intake of water to the pump. If no water is supplied, the pump is not switched
off and the resulting high temperature of the water in the pump head may damage the
pump. Caution: Danger of hot water escaping from the pump!
The anti-corrosion agent is classified as harmless to humans, animals and the environment!
The manufacturer cannot be held liable for damage resulting from failure to observe the
operating instructions or this supplementary sheet!
