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

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!
