move the hose, it is best to lever it off using a small screwdriver. Do
not pull the hose off by force or cut it open with a knife, as this may
cause damage to the hose connectors!
5.6 Adapter for other CO
With the suitable DENNERLE adapter, it is also possible to use other
sources of CO :
2
• Adapter (art. no. 2998) for standard reusable CO
(connection thread W21.8 x 1/14")
• Adapter (art. no. 2997) for Dennerle disposable CO
cylinders (connection thread M10 x 1.25)
5.7 Combination of Nano pressure reducer and solenoid
valve
IMPORTANT: If the Nano pressure reducer is fitted with a solenoid
valve for switching off the supply of CO
fit a hose with a compressive strength of at least 5 bar between the
pressure reducer and the solenoid valve. The black CO
suitable, as it is only able to withstand pressures of up to 3 bar.
We recommend the special Softflex CO
pressure-proof to 7 bar (art. no. 3060).
5.8 Information on CO Nano Flipper
2
The safe design of the collector ensures that the small quantities of
CO which are customary for nano aquaria are effectively dissolved,
2
while undesired large quantities of CO
via the waste gas vent.
While the CO bubbles rise in the Flipper, other gases which are na-
2
turally dissolved in the aquarium water penetrate into the bubbles.
These so-called waste gases are substantially lighter than the relati-
vely heavy CO and thus accumulate in the collector at the top. Here
2
they are discharged regularly via the special waste gas vent (slit).
The running-in period for the Flipper is approx. 2 days. Initially, the
individual CO bubbles combine to form larger bubbles. As soon as a
2
biological surface layer of microorganisms has formed, the bubbles
rise up to the collector.
