AUGA VarioFlow E Pond Pump

Welcome

Thank you for purchasing this AUGA VarioFlow E pond pump. We hope you enjoy many hours of water fun.

This manual provides essential information for the safe and effective operation of your pump.

Important Safety Information

⚠️ WARNING: Permanent Magnet: This pump contains a permanent magnet. The magnetic field can disrupt pacemakers, interfere with electric/electronic components, and erase data carriers. Persons fitted with pacemakers must maintain a safety distance of at least 1 meter (3.3 feet) from the pump.

ℹ️ General Usage Restrictions:

• This device is not intended for use by persons (including children) with impaired physical, sensory, or mental capabilities, or those lacking experience and/or know-how, unless they are under supervision or have received training from a responsible person.
• Children should be supervised to ensure they do not play with the device.
• Do not use the pump if you have not read and understood the operating instructions.

⚠️ Electrical Safety:

• The pump must only be connected to an installation with a residual current device (RCD/GFCI) of 30mA and a grounded power outlet.
• Ensure the mains voltage and current type match the information on the pump's nameplate or the specifications table.
• The power outlet should be placed in a moisture-free area, at least 2 meters (6.6 feet) from the water's edge.
• Before any work on the pump, always unplug it from the electrical outlet to cut off power.
• If the power cord, plug, or control panel is damaged, do not use the pump. Repairs are not possible as the cable is molded into the motor.
• Never move or suspend the pump by its power cord.
• Keep the plug dry. Form a U-shape loop in the cord to prevent water from running down the cable to the plug.
• Hang the control panel in a well-ventilated area, protected from direct sunlight and moisture/rain. The back wall should not be made of easily flammable material.

Design and Features

The AUGA VarioFlow E is an efficient, multifunctional submersible pump designed for reliable operation in various water features.

• Motor: Features a 6-pole, 3-phase, brush-free permanent magnetic motor for high efficiency and a long lifespan. The motor is fully encapsulated in synthetic resin (IP X8) for protection.
• Pump Axle & Bearings: Made from high-quality ceramics, providing excellent resistance to wear and tear.
• Control System: Equipped with a built-in single-chip micro-computer offering various safety functions, including protection against dry running, overheating, and overloading.
• External Control Panel: An external operating panel with push buttons and a digital display allows for stepless adjustment of the pump's capacity and power consumption.

Applications

VarioFlow-E pumps are suitable for pumping fresh water without chemical additives. They are ideal for:

• Circulation systems
• Filter systems
• Streams and watercourses
• Waterfalls
• Fountains
• Garden ponds
• Fish ponds
• Terrace fountains

Caution: For use in swimming lakes or pools where people are present, the pump must be installed exclusively out of the water, at a minimum distance of 2 meters (6.6 feet) from the pool edge, and in compliance with relevant safety guidelines and standards (e.g., DIN VDE 0100 parts 702 & 737, DIN EN 13451 parts 1-8). Consult an electrician if unsure.

Technical Specifications

Declaration of Conformity: The VarioFlow E series (E10, E20, E30) complies with the LVD Directive (2014/35/EU) and the EMC Directive (2014/30/EU), adhering to harmonized standards such as EN 60335-1, EN 60335-2-41, EN 55014-1, EN 55014-2, EN 61000-3-2, and EN 61000-3-3.

Installation and Commissioning

Installation in Water (Figures 1, 6, 8)

Important: Do not run the pump dry, as this can cause damage.

• Place the pump in the water to allow it to fill.
• To prevent contamination, place the pump on a stable stone tile to avoid sucking up sludge.
• Ensure a water depth of at least 10 cm (4 inches) above the pump to prevent air suction.
• The maximum immersion depth is 2 meters (6.6 feet).
• Position the pump housing correctly and connect the suction (Z) and discharge (D) hoses airtight.
• Connect the 4-pin power plug to the control panel's 4-pin female plug, ensuring the O-ring is in place and the nut is tightened securely.
• Place the control panel in a ventilated, non-combustible location protected from direct sunlight and moisture.
• Start the pump by inserting the plug into the socket and using the control panel.
• Protect the pump from frost.

Figure 8: Displays the 4-pin electrical connectors used for the pump and control panel.

Dry Installation (Figures 2, 3, 6, 8)

The pump can also be installed outside the water.

• Remove the pump's suction basket.
• Place the pump below the water level near the pond so water can flow into it (the pump is not self-priming).
• Position the pump housing correctly and connect the suction (Z) and discharge (D) hoses airtight.
• Before commissioning, the suction hose (Z) must be completely filled with water.
• Connect the 4-pin power plug to the control panel's 4-pin female plug, ensuring the O-ring is in place and the nut is tightened securely.
• Place the control panel in a ventilated, non-combustible location protected from direct sunlight and moisture.
• Start the pump by inserting the plug into the socket and using the control panel.
• Tip: Fit a pre-filter to the suction side to protect the pump from contamination.
• Protect the pump from frost.

Installation for Swimming Pools/Lakes (Figure 3)

For installations in swimming lakes or pools where people are present, follow these specific instructions:

• Install the pump exclusively out of the water, at least 2 meters (6.6 feet) from the pool edge.
• Ensure the installation complies with DIN VDE 0100 parts 702 & 737 and relevant manufacturer instructions.
• Adhere to standards like DIN EN 13451 parts 1-8 and DIN VDE 0100 parts 702 & 737.
• Create a shaft with a platform at least 2 cm (0.8 inches) from the water's edge.
• Protect the shaft with a cover.
• Install a run-off in the shaft for flood protection. If not possible, use a submersible pump with a float.
• Secure the pump to the platform with screws.
• Install a metal "M" coupling sleeve in the suction pipe for equipotential bonding connection.
• Consult an electrician if you have any doubts.

Operating the Pump

The pump is controlled using the VarioFlow E control panel (Figure 5).

• Display: Shows steps 0-100 (revolution speed) and power usage.
• Buttons:
• Power Button: Turns the pump on and off.
• Increase Capacity Button (c): Increases the pump's output.
• Decrease Capacity Button (d): Decreases the pump's output.
• The pump will revert to its last setting when turned off and on again.
• Attention: Avoid pressing buttons rapidly, as this can cause display errors. If this occurs, disconnect and reconnect the power plug for a reset.
• Hold the capacity buttons continuously to increase or decrease output quickly.
