✓ Site is prepared.
✓ Pressure pipe properly installed.
1. Screw the discharge pipe fully into the pump’s discharge con-
nection.
2. Position the pump at the installation site.
CAUTION! Use a hard surface or underlay at the installation
site to prevent sinking on soft substrate.
3. Connect the discharge pipe to the pressure pipe (e.g. using a
flexible hose section).
4. Secure the connection cable to the pressure pipe and route it
to the socket/power supply.
▶ Pump is installed.
5.2.2 Portable wet well installation
The pump can be installed at any location on the application site
when carrying out portable wet well installation. Observe and ad-
here to the following points:
• Secure the pump against falling over and moving (creeping)
during use.
• Secure the pressure hose to the hose connection.
✓ Site is prepared
✓ Pressure hose to be used: Min. inside diameter 1½"
✓ Hose clip to be used: 40 − 60 mm inside diameter (1.6 − 2.4 in)
✓ Hose connection to be used: G 1½" (with male thread)
1. Attach the hose connection.
Twist the hose connection into the pressure port as far as it
will go.
2. Slide the hose clip over the pressure hose.
3. Slide the pressure hose onto the hose connection at the pres-
sure port.
4. Secure the pressure hose to the hose connection using the
hose clip.
5. Position the pump at the installation site.
CAUTION! Use a hard surface or underlay at the installation
site to prevent sinking on soft substrate.
6. Lay the pressure hose and fasten it in the appropriate place
(e.g. drainage).
CAUTION! If the pump is placed in a full
chamber, hold the pump at a slight angle when immersing.
This causes the air to escape from the pump!
7. Route the connection cable to the socket/power supply.
▶ Pump is installed.
5.3 Electrical connection
• Mains connection with correctly installed protective earth con-
ductor.
• Residual-current device (RCD) is installed with 30 mA.
• Mains connection fuse protection: max. 16 A.
• Voltage (U) and frequency (f) data on the rating plate corres-
pond to the data of the mains connection.
Do not connect the pump if:
• The connection cable is damaged
Have the connection cable replaced by a qualified electrician or
the customer service.
• A standalone inverter is in use
Stand-alone inverters are used in autonomous power supplies,
e.g. solar power supply, and can generate overvoltages. Over-
voltages can destroy the pump.
• A multiple plug socket or power strip is in use
• An energy-saving plug is in use
This reduces the energy supply to the pump and the pump may
heat up too much.
• Operation on start-up controls
The pump is not suitable for operation on a frequency converter
or a soft start control.
• Explosive atmospheres
Do not connect and operate the pump inside potentially ex-
plosive atmospheres!
5.3.1 Connection: Pump with plug
Provide for a socket (type E or type F) with earthing contact. To
connect the pump, insert the plug into the socket.
