• The maximum delivery head is 7 m.

Technical Data

Safety Instructions

[CAUTION]: This device is not intended for use by persons (including children) with limited physical, sensory, or mental capabilities, or with lack of experience and/or knowledge, unless they are supervised by a person responsible for their safety or have received instructions from them regarding the proper use of the device. Children should be supervised to ensure they do not play with the device.

General Safety Precautions:

• Use the device exclusively for its intended purpose as specified in these operating instructions.
• You are responsible for safety in the work area.
• Should the cable or plug be damaged due to external influences, the cable must not be repaired but replaced with a new one. This work must only be carried out by a qualified electrician.
• The voltage specified on the device's rating plate, 230 V (50 Hz) AC, must correspond to the existing mains voltage.
• Never lift, transport, or secure the device by its power cord.
• Ensure that electrical connections are protected from flooding and moisture. Always pull the power plug before working on the device.
• Avoid exposing the device to a direct water jet.
• The operator is responsible for compliance with local safety and installation regulations. Consult an electrician if necessary.
• The user must prevent consequential damage from flooding of rooms in case of device malfunctions through appropriate measures (e.g., installation of an alarm system, backup pump, etc.).
• In case of a device failure, repair work must only be carried out by a qualified electrician.
• The device must never run dry or be operated with the suction line fully closed. No warranty is provided for damage to the device caused by dry running.
• The device must not be used for swimming pools.

[WARNING]: Read all safety instructions and instructions. Failure to comply with safety instructions and instructions can cause electric shock, fire, and/or serious injury. Keep all safety instructions and instructions for future reference.

Durability and Compatibility

• To ensure a long service life, only organic toilet wastewater, water, and paper should be disposed of with the lifting station.
• The maximum temperature of the conveyed fluid should not exceed 80 °C during operation.
• This pump must not be used to convey flammable, gas-forming, or explosive liquids. This pump must not be used for other liquids, especially not for motor fuels, cleaning agents, and other chemical products!

Important: Only toilet paper, urine, and faeces belong in a WC. Everything else belongs in the waste bin!

Please note that wastewater must be introduced into the lifting station without pressure!

Note: Included accessories may be partially located inside the lifting station upon delivery. Please remove the accessory bag before installation.

Installation

• The lifting station is installed according to EN-12056-4.
• The lifting station can be operated with any standard toilet with a horizontal outlet. The center point of the horizontal outlet must be 18 cm above the floor according to EU standard (rough construction: 18 cm above finished floor level).
• Important: PRESSURELESS: When connecting a washing machine to the lifting station, the wastewater hose must not be connected directly to the lifting station, but must be fed via a vented piping system (e.g., via a sink that can slowly introduce wastewater into the unit). Direct connection can cause the collection tank of the lifting station to burst, and this is not a warranty case.
• We recommend having the assembly and leak testing carried out by qualified personnel. Please observe the legal regulations!

[ATTENTION]: When installing, ensure that the pump is not mounted suspended on the pressure line or the power cable.

Functional Principle

• The lifting station consists of a tank that collects the incoming wastewater and an electric pump that is automatically controlled by a pressure switch (D).
• The conveying function is triggered when the flush is activated, just like with a normal toilet.
• The substances to be conveyed are collected in the tank (A). The air chamber (B) measures the air pressure flowing through the pipe (C) to activate the pressure switch (D). The pressure switch starts the motor (E), which drives the turbine/grinder (F). The wastewater is discharged through the outlet (G).
• This mechanism is simple, and the device is made of high-quality materials. The functionality is based on a proven concept.

Diagram illustrating the functional principle with components labeled A through G.

The lifting station, consisting of a housing with a built-in pump, automatically grinds acidic, fatty, and hot water (up to 80 °C), faeces, and toilet paper, discharging it via a pipe with a diameter of 23 mm, 28 mm, 32 mm, or 44 mm to the nearest sewer.

It collects the intended wastewater from sanitary facilities in bathrooms (EN-12050-3, EN-12050-4) or kitchens, including washing machines, dishwashers, and all other appliances whose wastewater needs to be disposed of (see performance curve).

The non-return valve included in the packaging must be installed.

The standard EN-12050-3, EN-12050-4 stipulates that if a WC is connected, only a shower, a bidet, and a sink can be connected.

The lifting station cannot be installed on appliances like washing machines and dishwashers if it is connected to the toilet.

If the water inflow into the tank cannot be interrupted during normal operation, a device must be used that is capable of doing so and which switches on automatically if necessary.

Installation must comply with the European standard EN 12056-4.

Fasten the tank with two dowels (Ø 3.5 mm) or similar, using the provided fastening holes.

The lifting station can be connected to any WC model with a wall outlet according to European regulations.

Attachment is done by inserting the WC outlet into the rubber sleeve that comes out of the housing and screwing on the supplied clamp.

Connections and Minimum Heights

• The outlet connection is on the top of the unit. Other appliances in the bathroom or kitchen are connected to the side of the lifting station.
• The connected appliances should be operated separately and not continuously (e.g., shower).
• By the way: The outlets of shower trays and bathtubs must be at a minimum height of 10 cm from the floor. All connected sanitary facilities must be able to interrupt the water flow.

Diagram illustrating required minimum height for shower trays, showing a 100 mm minimum distance from the bottom edge of the shower tray to the water inlet.

The lifting station is equipped with an activated carbon filter for ventilation of the tank in the pump room. If the auxiliary inlets are not used, mount the corresponding blanking plug.

Toilet and Sanitary Unit Connections

• Connect the horizontal outlet of the toilet bowl to the rubber sleeve of the lifting station and tighten the connection with the supplied clamp. Ensure you use a lubricant if necessary so that the rubber connection does not tear.
• Connect the drain pipe to the rubber connector piece; the pipe should have a diameter of 40 mm or 32 mm. Seal the connection with the clamp.

Non-Return Valve Installation Check

If wastewater is to be pumped upwards, install the non-return valve as close as possible to the lifting station.

Connecting Toilets and Other Sanitary Units

Connect the drain pipes of other sanitary units with the supplied rubber connector pieces and tighten them with the clamp. For wastewater from showers and bathtubs, ensure that the siphon has a gradient of at least 1% (1 cm/min) so that the wastewater flows to the lifting station by natural gravity.

If other sanitary units are connected along the disposal circuit near the lifting station, install non-return valves in the respective drain pipes to prevent backflow. The gradient of the horizontal components must be at least 1%.

Installation Possibilities

• For the lifting station to activate when wastewater is introduced, the supply wastewater pipe should have a gradient of at least 2-3% and a height difference of at least 20 cm, measured from the siphon to the inlet of the lifting station.
• Both conditions are necessary for the pressure switch in the toilet lifting station to be triggered, the lifting station to switch on, and the water to be pumped out.
• Possible errors if these conditions are not met:
• The lifting station does not pump the water.
• Residual water remains in the pipelines.
• Residual water remains in the shower tray.

Maintenance and Cleaning

• Read the safety instructions and the manual carefully before opening the device for maintenance. Maintenance should only be performed on a de-energized device.
• The lifting station consists of a wastewater collection tank and the grinder with a pressure switch. Both areas are easily accessible via the lid. The maintenance access points are clearly marked on the top of the lifting station. Maintenance and repair of the device are conveniently possible.

Removing Foreign Objects and Blockages

• Disconnect the power plug.
• Unscrew the cap with the pump symbol (top of the lifting station).
• Remove the cap.
• Unscrew the cap of the grinder chamber.
• Turn and remove the cap of the grinder chamber.
• Remove obstructing parts (e.g., with pliers).
• After completing the maintenance, reassemble the device in the reverse order.

Troubleshooting

Our devices are exclusively designed for disposing of faeces and toilet paper. Some small components may still be pumped through, but larger components can block the pump. This is the main reason for malfunctions reported to our customer service.

Detailed Error Descriptions and Solutions

Residual Water in Shower Tray

For the lifting station to trigger correctly when wastewater is introduced, the supply wastewater pipe should have a gradient of at least 2-3% and a height difference of at least 20 cm from the siphon to the lifting station inlet.

Both conditions are necessary for the pressure switch in the toilet lifting station to operate correctly, for the lifting station to switch on, and for the water to be pumped out. Possible errors if these conditions are not met include:

• Lifting station does not pump water.
• Residual water remains in the pipelines.
• Residual water remains in the shower tray.

Loud Noises, Motor Not Running or Running Poorly, Water Not Pumped

These symptoms occur with a blockage in the lifting station.

If the unit is blocked by toilet paper and faeces, it is usually sufficient to rinse the system backwards with water. To do this, simply apply a little water pressure to the outlet of the lifting station, e.g., with a garden hose, so that the residues from the pump body are flushed back into the lifting station. Please ensure that no water pressure is applied to the collection tank of the lifting station. Otherwise, the pressure switch of the lifting station will be damaged, and the automatic on/off function will no longer work correctly.

For more severe blockages/obstructions by solid objects that have become jammed in the pump body, it may be necessary to open the pump to remove the solid objects.

Severe impacts from solid objects in the lifting station can even cause damage to the motor bearings. In this case, the motor of the lifting station must be opened and the bearings replaced. This fault usually manifests itself after removing or flushing out larger solid objects. The lifting station can still be turned freely by hand, but as soon as you try to start the motor, it jams and only hums.

Cleaning can be done without problems via the maintenance opening on the top of the lifting station.

Lifting Station Does Not Pump and Runs Continuously

This error occurs with lifting stations that have been switched off (no power) but have still received inflow, or where wastewater has been introduced under pressure from a dishwasher or washing machine, or where the inflow has exceeded the pump's capacity. This has caused the units to become "overfilled".

In this case, water may enter the pressure switch of the lifting station. This disrupts the pressure switch's function. The unit then either runs continuously or does not switch on automatically anymore.

Cleaning the Unit

The lifting station must only be cleaned from the outside with mild cleaning agents, a damp cloth, and soapy water. Damage caused by incorrect cleaning agents is not covered by the warranty.
