reduced physical, sensory or mental capabilities or lack of experience and knowledge
if they have been given supervision or instruction concerning use of the appliance in a safe
way and understand the hazards involved
- children shall not play with the appliance
- cleaning and user maintenance shall not be made by children without supervision
2. Installation
• The maximum total head, in meters : 7.5m
• Pollution of the liquid could occur due to leakage of lubricants.
• The pump must not be used when people are staying in the water
• The pump must supplied through a residual current device
(RCD) with a rated residual operating current ≤ 30 mA
3. Electrical connection
• If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.

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.

PRECAUTION BEFORE USING THE PUMP
5. 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 adhere 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 32mm
-> Hose clip to be used: 32 – 40mm inside diameter
-> Hose connection to be used: 32mm(with female thread)
-> Attach the hose connection.
Twist the hose connection into the pressure port as far as it will go.
-> Slide the hose clip over the pressure hose.
-> Slide the pressure hose onto the hose connection at the pressure port.
-> Secure the pressure hose to the hose connection using the hose clip.
-> Position the pump at the installation site.
CAUTION! Use a hard surface or underlay at the
installation site to prevent sinking on soft substrate.
-> 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!
-> Route the connection cable to the socket/power supply.
-> Pump is installed.

9. Take care of handling the pump.
Prohibit to impact the pump.
• Never carry the pump by the holding of cable itself.
• Care should be taken during installation that the pump
is not allowed to be mounted suspended freely on the
delivery pipe or on the cable. It must rest on a stabile
surface and/or be suspended on a handle with a rope.
11. When connect or disconnect an electric power
to the pump for service, installation and repair,
it should be cut off the electric switch.
• Electric connections must be protected from moisture.
10. The permitted voltage of this pump is ±10% of the rated voltage.
Otherwise it will be the reason of shortening the service life of the pump.
6. Avoid operating under the condition of dry running and
delivering no water.
For it will shorten the service life of pump and also
cause the trouble of motor.
7. Avoid using the pump nuder condition of hot water over
40℃For it will be shorten the service life of pump.
8. Be careful not to use the pump solvent such as benzol,
acid, inflammable liquids such as gasoline.
When it is used for them, there is the risk of the fire and
it will cause the trouble of the pump and also shorten
the service life of it.
