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 to the top of the grey PVC pipe which is located between the two
outlet pipes to supply the venturi pump with air. 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 opposite side of the outlet pipes. Attach the union and the hose
•
tail (22 x 20 mm).
We recommend a pump with a capacity of 2,000 to 4,000 litres/hour (500 – 1000 gph) e. g.
•
Ocean Runner 3500, for the water supply.
Note: 1.The ball valve at the bottom must be closed before you start to fill the skimmer!
2. Ensure the availability of a sufficient quantity of usable sea water. The 5000 single
and 5000 twin take approx. 50 litres of water, the type 5000 baby approx. 25 litres.
3. Fit the rubber sealing ring for the bayonet socket of the reaction pipe.
4. Push the bayonet socket into its seating and turn it to lock. Then fit the collection cup.
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 32 mm 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.
After first use or after cleaning the skimmer, it takes some time for the initial foam to build up in
the reaction pipe of the collection cup. This is because the cleaned acrylic initially reacts with the
water until a build up of fatty acids naturally takes place.
After approx. 24 hours, the foam should be pushed slowly and evenly into the collection cup. The
quantity of liquid and organic substances depends on the pollution of the aquarium.
5. Maintenance
Collection cup: Depending on the organic load the cup should be cleaned daily to weekly.
•
Reaction pipe: This needs only occasional cleaning, we recommend intervals from 6 to 12
•
months.
Venturi pump(s): The maintenance of the pump(s) should be done at the same time as that of
•
the reaction pipe:
Drain the water out and dismantle the pump. Flush the pump housing and the needle wheel
with clean water.
The same should be done with the air injection nozzle.
