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
• Do not force CO2 cylinders open.
• Release CO only using a DENNERLE pressure reducer for CO
2
Exclusive) with M 10 x 1,25 thread!
• Release CO out of upright cylinders only. Secure against tipping over.
2
• CO gas is heavier than air and causes suffocation at high concentrations, therefore:
2
• Do not inhale CO gas. • Store out of reach of children.
2
• 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
e.g. open window, blower switched on, etc.
• Do not refill disposable CO cylinders!
2
• Place only completely empty cylinders into recycling containers.
How the CO fertilizer system
2
Professional works
The CO pressure reducer Professional reduces the cylinder pressure to an ope-
2
rating pressure which the user can set in line with practical requirements. The
precision needle valve enables highly exact and very simple CO dosage. The
2
CO CO
is transported to the aquarium via the special leak-proof
2 2
CO Flipper ensures effective dissolving of the CO in the aquarium water. A
2
2
CO
special check valve protects the valuable pressure reducer from any back-
2
flowing water. The CO content in the aquarium water can be read directly by
2
CO
means of the long-term test Correct.
2
The disposable 500 g CO cylinder is particularly practical and convenient. It
2
CO
will supply over a long period before it needs replacing. And the frequently
2
laborious refilling process for reusable cylinders is a thing of the past!

Set-up and connection
Note: You may notice a brief "hiss" when screwing or unscrewing the pres-
sure reducer, similar to the sound when you open a bottle of mineral
water.The cylinder pressure manometer will now indicate approx. 60 bar
(at 20 °C).
IMPORTANT: Secure the

times. The cylinder must always be in an upright position when supp-

1. Connect the pressure reducer
• 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 clo-
sed). IMPORTANT: Tighten only gently!
• Turn setting screw for operating pressu-
re towards " – " as far as it will go.
• Pull green protective cap off the cylinder
valve.
• Screw pressure reducer hand-tight onto
CO
cylinder without canting by turning

slowly in clockwise direction.

2. Fit check valve in CO hose
2
• Use a strong pair of scissors to cut
through the CO hose approx. 10-20 cm
2
from the free end, leaving a straight cut
edge.
• Unscrew both coupling rings from the
CO check valve.
2
• Fit coupling rings to the ends of the hose
and slide hoses as far as it will go onto the
hose connectors of the check valve.
IMPORTANT: The arrow on the check valve
must point in the CO flow direction!

pressure reducer
• Unscrew coupling ring from the hose
connector of the pressure reducer and
slide onto the free end of the CO hose.
2
• Slide CO hose as far as it will go onto
2
the hose connector and fix with coupling
ring.
4. Connect the CO Flipper
2
• Rinse the CO Flipper with warm tap
2
water. Do not use detergent!
• Plug the CO supply hose onto the hose
2
connector. TIP: Dipping the end of the
hose into hot water briefly beforehand
makes it easier to slide it over the hose
connector.
• In the aquarium, select a spot with good
but not too strong water circulation. The
spot should not be too bright to prevent
possible algae growth.
• Using the suction cups, attach the CO
2
Flipper vertically, with the 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.
