Water level regulation for overflow systems
The DrainTuna can be used to maintain a constant water level in aquarium overflow chambers. The DrainTuna
is only suitable for use with Aqua Medic DC Runners from the x.2 and x.3 series.

2. Safety instructions
- When working in the aquarium, always disconnect all units from the power supply system before putting your
hands into the water. Connect all units to the mains via a residual current device with a maximum residual
current of 30 mA.
- Connection to pumps other than those mentioned in the instructions is not permitted.
- Suitable for indoor use only.
- Protect the controller from moisture (humidity < 80%), splash water and condensation.
- We recommend forming drip loops with the cables to prevent any water running along the cables from getting
into sockets.
- The electrical data of the DrainTuna must match the data of the power supply unit used (12 V DC). This data
can be found on the rating plates.
- Not suitable as a toy for children.
3. Start-up
The following operating procedure applies to Aqua Medic DC Runner pumps of the x.3 series:
3.1. Place the float holder in the drainage shaft so that the marking (Fig. 3, No. 3) is at the height of the
desired water level and fix it in place using the screws (Fig. 3, No. 4). Lower the water level until both float
bodies are at the bottom.
