Observe the following points when installing a diaphragm hand pump:
- Select an installation height which is optimal for operation.
- Connect the diaphragm hand pump to the emergency drain (lowest point, almost complete drain possible).
- A hole saw 30 mm (1.3 in) is required to open the drain connection.
- Connect the pressure pipe downstream of the gate valve on the pressure side.
- Alternatively, the connection can be made via a pipe loop directly to the sewer.
- All connections must be completely tight!
- Observe the installation and operating instructions for the diaphragm hand pump!
