When starting the aquarium, water has to be filled in until the filter tank is filled up to 10 – 12 cm in the front
part and then the pump has to be started. If the water level in the filter tank decreases, water has to be filled
in until the a.-m. maximum is reached. Take care that enough space is left so that the inflowing water in case
of failure or shutdown of the circulation pump still fits into the filter tank. If the overflow produces splashing
noises, the drain easy drain (Fig. 2, No. 5) should be closed in small increments (clockwise rotation) in order
to increase the water flow in the overflow. At least in the initial phase, it has to be checked regularly and
readjusted, if necessary. Only make quarter turns and then wait at least 5 - 10 minutes so that the system has
sufficient time to compensate. Attention: the water level in the filter tank changes. If the drain is closed
too much, the water flows into the filter tank via the emergency overflow.
Always re-tighten all bushings before use. The slide ring and nut have to be mounted manually beforehand and
tightened as much as possible. The rubber slide ring must always be attached to the side of the rotable nut, the
rubber gasket on the opposite side of the panel.
