1. Handling
The pump must be lifted and handled carefully by means of the handle and the lifting holes.
2. Usages
The pump is available for the transfer of clean, polluted and turbid liquids, which contain
suspended materials that do not exceed the following dimensions. Its most common uses
are as follows: It can be used for draining domestic waste water collectors, rain water
collectors, in flooded environments, and in the excavations and pits of the construction
industry (EPP 30V or EPP 30T may be used). Vortex pallet models are also suitable for the
transfer of liquids that contain suspended filament materials.
3. Usage Limits
EN 60335-2-41 standard prohibits using the pump in tanks or swimming pools that contain
people, and obligates the use of the versions with a 10m cable for outdoor use.
Fluid Temperature: ≤ 35°C
Note: The pumps must be submerged until the minimum submersion depth.
4. While installing the pump
The size of the pit must be at appropriate dimensions to prevent frequent operation and the
floater should
be adjusted carefully.
5. Electrical Connection
The pumps must be used with an ETNA Evo -1/7.5 electrical panel.

6. Control of the Direction of Rotation
The correct direction of rotation is clockwise when looking at the pump from above.
Observe and check the pump performance. With the correct direction of rotation, high
Q/H performance is ensured with single channel and double channel versions, and a low
absorption rate is provided with vortex wheeled versions.
7. Maintenance
Please make sure that you power o if any maintenance is required on the pump and call
an expert for the maintenance operation.
The pump does not require any routine maintenance. Cleaning the suction filter (EFP 30D,
EFP V) or the wheel may be required. Remove the screws that hold the filters to access
the wheel on the models with filters.
8. Safety Information
• The pump is not suitable for pumping flammable or dangerous liquids.
• Do not use the energy cable to carry or lift your pump.
• Do not run the pump dry (out of the water).
• Since the pump runs and stops automatically, do not put your hands or other objects in
between when it is connected to the mains.
• Pay attention to the limitations of use. Inappropriate use may damage the pump or
people.
• Ensure that the network voltage conforms to the value on the label.
• If the pump is three-phase, have the connections to the electric grid and the earthing
socket conducted by an expert (authorized electrician).
• Use a sensitive phase relay (0.03A) as extra protection against electric shocks.
• Restrict the access of individuals, who are not authorized to maintain the pump.
• Use the pump within the usage limits defined on the label.
• Protect the pump against freezing.
• Protect the pump against potential blockages.
• We recommend that you wear gloves during any action conducted on the pump.

9. Troubleshooting
The motor starts running but the pump does not transfer. Make sure that water level is not
very low and the suction nozzle or the discharge pipe is not clogged.
If the transfer of the pump is reduced. Check for blockages and check the accuracy of the
rotation direction on the three-phase models.
If the pump runs intermittently.
- The floater switch adjusted wrong.
- The container of the pump is very small.
- The current withdrawn from the electrical panel is high.
- The pump or the pipes are clogged.
10. Noise
If the pump runs partially under water, the noise level should be less than 70 db(A), but this
value is not applicable when the pump runs completely under water.
11. Immersion Sledge
The immersion sledge is a fitting that provides ease of installation and maintenance in
cases where the pump is required to run on a fixed point. As seen on diagrams 12 and 13,
thanks to its sledge system, the pump is easily suspended into a well using a chain through
its stainless steel guide pipes and when it is directly across from the flange located at the
bottom of the sledge, it sits onto the discharge flange, and is ready for operation. Discharge
of the chamber, where the pump is located, is not required during this process.
When maintenance is required, the pump is pulled up using a chain, cleaned by spraying
clean water onto it with a hose, easily taken out, and the maintenance operation is
performed. The pump is lowered into the well on the sledge again after maintenance and is
ready for operation. It is recommended to use a strong chain when suspending the pump
down on the sledge.
