Safety rules for carbon dioxide (CO ) cylinders)
2
• Use only for supplying CO to aquaria.
2
• CO cylinders are under high pressure. Therefore, please observe the following:
2
• Do not throw CO cylinders. Store in a cool place. Protect against sun and temperatures above 50°C.
2
• Use only when fitted with suitable pressure reducers for reusable CO
models Profi 2000, Compact, Professional und Exclusive.
• Release CO out of upright cylinders only. Secure against tipping over.
2
• Do not force CO cylinders open.
2
• Do not fully empty CO -cylinders. Refilling is only allowed at authorized filling stations. Please note: Tare weight without cage. Unmount cage before
2
refilling.
• CO gas is heavier than air and causes suffocation at high concentrations, therefore:
2
• Do not inhale CO gas.
2
• Store out of reach of children.
• Store CO cylinders in a well-ventilated place and not in basement rooms.
2
• When transporting individual cylinders in vehicles please observe the following: Secure against sliding or rolling around, otherwise the valve may be
damaged, causing CO gas to escape. Provide for ample ventilation, e.g. open window, blower switched on, etc.

How the CO fertilizer system
2
Professional works
The CO pressure reducer Professional reduces the cylinder pressure to
2
an operating pressure which the user can set in line with practical requi-
rements. The precision needle valve enables highly exact and very sim-
ple CO dosage. The CO Flipper ensures effective dissolving of the CO
2 2
in the aquarium water. A special CO check valve protects the valuable
2
pressure reducer from any backflowing water. The CO content in the
2
aquarium water can be read directly by means of the CO long-term test

Note: It is also possible to fit the CO
in the hose. However, please note that the shorter the distance is bet-
ween pressure reducer and check valve, the faster and simpler it will
be to set the number of bubbles.
1. Connect the pressure reducer
• Place reusable CO cylinder in stand.
2
• Pull black protective cap off the
needle valve of the pressure reducer.
• Close the needle valve by turning in
clockwise direction (if it is not yet
closed). IMPORTANT: Tighten only
gently!
• Turn setting screw for operating pres-
sure towards " – " as far as it will go.
• Fit pressure reducer to CO cylinder

ring with 30 mm spanner.

• Fit coupling rings to the free ends of the

• Unscrew coupling ring from the hose

hose and fix with coupling ring.
4. Connect the CO Flipper
2
• Rinse the CO Flipper with warm tap

water. Do not use detergent!
• Plug the CO supply hose onto the
2
hose connector. TIP: Dipping the end
of the hose into water briefly before-
hand makes it easier to slide it over
the hose connector.
• In the aquarium, select a spot with
good but not too strong water circulati-
on. The spot should not be too bright to
prevent possible algae growth.
• Using the suction cups, attach the
CO Flipper vertically, with the
2
collector facing upwards, at least 5
cm below the surface of the water.
Ensure that plants do not obstruct
the circulation of water through the
slits of the CO Flipper.
