PRECAUTION BEFORE USING THE PUMP
4. Stationary wet well installation
• For Stationary wet well installation, the pump is installed directly onto the pressure pipe.
Observe and adhere to the following points:
- The connected pressure pipe must be self-supporting.
The pressure pipe must not be supported by the pump.
- The pump may oscillate slightly during operation.
These oscillations must be dissipated via the pressure pipe.
- Ensure that the connection to the pressure pipe is stress-free – do not screw it too tightly.
- The pressure pipe must not be smaller than the pump’s discharge connection.
- Seal pipe connections with Teflon tape.
- Install all specified valves in accordance with local requirements
(gate valve, non-return valve.)
- Lay the pressure pipe frost-proof.
- Avoid air intake! Air in the pump and in the pipe system can lead to delivery problems.
Air pockets must be removed using the ventilation systems!
- Install the pressure pipe as a “pipe loop” to avoid backflow from the public sewer.
At its highest point, the bottom edge of the pipe loop must be above the locally determined
backflow level!
-> Site is prepared.
-> Pressure pipe properly installed.
-> Screw the discharge pipe fully into the pump’s discharge connection.
-> Position the pump at the installation site.
CAUTION! Use a hard surface or underlay at the
installation site to prevent sinking on soft substrate.
-> Connect the discharge pipe to the pressure pile
(e.g. using a flexible hose section).
-> Secure the connection cable to the pressure pipe and
route it to the socket/power supply.
-> Pump is installed.
