NOTE:
- Do not produce a vacuum of more than 100 mbar, as otherwise the vacuum will cause the shutoff valve to open.
- If no vacuum can be built up, replace the shutoff valve.
- Coat the sealing ring of the new shutoff valve with tyre fitting lubricant prior to installation.
- The shutoff valve can only be installed in one position: with the electrical connection facing upwards.
