Connecting the discharge pipe
1 | Discharge port with flange connector |
To connect the discharge pipe, follow these points:
- Make sure that the discharge pipe is DN 100.
- Be conscious of the flow rate in the discharge pipe: 0.7 m/s (2.3 ft/s) to 2.3 m/s (7.5 ft/s).
- Do not decrease the pipe diameter.
- Make sure that the pipes are self-supporting: No tensile or compressive forces are applied on the discharge port.
- Make sure that all connections are fully tight.
- Install the discharge pipe as a “pipe loop” to prevent backflow from the primary public sewer.
- At the highest point, the bottom edge of the pipe loop must be above the locally given backflow level.
- To prevent frost, install the discharge line sufficiently deep.
- The lifting unit is installed.
- The shut-off valves and non-return valves are already built in.
- Route the discharge pipe to the discharge port. Refer to the consulting documents for the accurate dimensions of the lifting unit.
- Put a seal between the flange connectors at the discharge pipe side and the discharge port side.
- Fasten the flange connectors with screws. Tightening torque: 45 Nm (33.2 ft·lb).
- The discharge pipe is connected. Next step: Connecting the inlet.
