What precautions do I need to take?

Before installation or maintenance, or before putting your hands into the aquarium, remove the power supply from all the electrical devices under water. Read the instructions.

Before installation

Check that all the components of the product are undamaged, disconnect all the electrical devices and make sure the voltage of the product corresponds to the mains voltage.

What is the purpose of the product?

This is an aquarium pump for internal use only, with water of a temperature of up to 35°C (95°F).

Why is the pump indicated as "universal"?

Because the Seltz pump has been designed so it can be safely used both in and out of the water, provided the pump is connected to the suction and delivery tubes. The pump must in any case operate under head.

What does "under head" mean?

It means that the pump must operate below the surface of the liquid if it is to pump, and needs to be primed in order to start it up.

How can I apply the tubes?

By grafting a flexible PVC tube onto the connections provided and screwing on the red ring nut to tighten the tube.

How can I use the mounting base?

The mounting base is the support for the pump. Using the suction cups provided, it can be applied to the bottom of the aquarium or the sump. The suction cups are useful to dampen the vibrations.

What maintenance operations are recommended?

The pre-filter, rotor and rotor cavity should be cleaned. If the pump is only partially submerged, it is necessary to remove the limescale that has formed on the outside of the pump.

My SELTZ L 20-30-40 pump is noisy: what can I do?

If the pump is clean and has been maintained properly, and makes an unusual noise and/or if performance is evidently affected by sudden changes in voltage, it is sufficient to restart the pump.
