3. Principle of Operation
The aquarium water is pumped to the skimmer using a separate pump (not supplied) which
should have a capacity of approx. 2,000-4,000 litres/hour. The relative positions of the inlet
and outlet ports ensures the maximum contact time of the air bubbles in the counter current. If
the SHORTY COMPACT is mounted in the cabinet, it can be supplied with water directly
from the overflow of the aquarium. In this case a bypass should be installed, so the volume of
water can be adjusted
The venturi pump draws the water from the skimmer and mixes it with air. Within the pump
housing the bubbles are cut into very fine pieces by the
needle wheel. The
air/water mixture is pumped back into the skimmer.
The treated water flows out of the bottom of the skimmer and is pumped through the two
transparent pipes positioned outside the skimmer back into the aquarium or filter sump.
4. Installation
•
Check that the sealing rings for the unions are in place.
•
Slot the holding plate for the venturi pump to one side of the skimmer. Push the pump on
to the holding plate and connect the pump to its union.
The PVC air tube should be fed so, that the end is higher, than the water level in the skimmer
.
This air tube must not hang down.
It should only jut out 5 cm at the top.
Connect the bottom end of the tube to the air intake of the pump.
•
The water inlet is located at the same side as the outlet pipes. Attach the union and the
hose tail (20mm).
•
We recommend a pump with a capacity of 2,000 to 4,000 litres/hour for the water supply
or direct connection to the aquarium overflow.
•
Fit the rubber sealing ring for the bayonet socket of the reaction pipe.
Push the foam cup into its seating and turn it to lock.
The drain from the skimmer has to run freely into the aquarium. A PVC pipe (40 mm dia) can
be glued into the drain ports. It is possible to let both drains flow into one pipe, but the
diameter of the pipe must not be reduced. If the drains are left separate, a reduction in pipe
size to 32mm is possible.
The skimmer can now be filled by pumping directly from the aquarium. Ensure that the water
level of the aquarium is not lowered too much. As soon as the water level in the skimmer
reaches the height of the venturi pumps, these pumps should be started.
Top up with sea water as necessary.
