Aqua Medic DrainTuna Manual De Instrucciones página 6

Connect the middle, right-hand socket (IN DC 12 V) to the 12 V power supply unit of the DrainTuna (do not
plug the 24 V power supply unit of the DC Runner pump into this socket!) Connect the power supply
unit to the mains. The green LED (Fig. 1, No. 1) on the DrainTuna lights up.
Connect the middle, left-hand socket (OUT 0 - 9 V) to the 0 - 10 V input of the DC Runner Controller (Fig. 2,
No. 1). The display 0 - 10 V appears in the controller.

3.3. Set the pump output to the desired maximum value using the rotary knob (Fig. 1, No. 6) on the DrainTuna.
Fig. 3: Adjust the water level in the overflow so that it is just below any emergency overflow (1) that
may be present.
3.4. The mechanical drain tap is set so that the water level slowly reaches the mark (Fig. 3, No. 3).
If the power of the feed pump changes significantly due to soiling, the DrainTuna setting must be adjusted. This
also applies after cleaning the feed pump or after changing the setting of the flow pumps used in the aquarium,
which have a major influence on the flow of water into the overflow. However, experience has shown that the
water level in the overflow remains constant for a long time with the help of the DrainTuna, as the DrainTuna
can compensate for such changes, provided they do not become too large.
Display of the DrainTuna:
- Green LED (Fig. 1, No. 6): Power ON.
- Red LED on the left (Fig. 1, No. 2): Both floats down = water level too low.
The DrainTuna increases the pump output to the set value + 8%. If this is not sufficient, close the easy drain
or tap further and/or increase the pump capacity.
