• JBL PROFLORA CO ADVANCED SET: With these systems, the pH control unit takes over the automatic maintenance of the desired pH value.
9. Note on the pressure displayed on the pressure regulator
In the CO pressurised gas cylinders, the CO gas is under high pressure. This pressure depends on the ambient temperature. At room temperature
(approx. 20 °C), the left pressure gauge of the pressure regulator shows a pressure of about 50 bar. This increases as the room temperature rises.
Thus at 30 °C, the pressure gauge shows about 70 bar. The pressure in the CO pressurised gas cylinder is not a measure of how full the cylinder is.
It will remain constant at the temperature-related value until shortly before the cylinder is empty. How much CO is in a CO pressurised gas cylinder
can only be determined by weighing it. The empty weight (tare) is stamped on the cylinder. The current weight minus the tare gives the available
amount of CO .
The pressure in the CO pressurised gas cylinder is regulated down to an easy-to-handle so-called „working pressure" by the pressure regulator. The
right-hand pressure gauge of the pressure regulator shows this working pressure. It is preset to approx. 2 bar in the JBL PROFLORA CO REGULA-
TOR BASIC pressure regulators. When changing the working pressure, it is important that a decrease in CO takes place, i.e. the adjustment screw
must not be closed, otherwise the new working pressure cannot regulate itself.
10. Changing cylinders
If the cylinder pressure on the left-hand pressure gauge falls below 30 bar, the refillable CO pressurised gas cylinder needs to be refilled within
the next 2 - 3 days. The disposable CO pressurised gas cylinder may only be changed when it no longer contains CO . This is when both pressure
gauges show 0 bar or no more CO bubbles rise in the aquarium.
Disposable CO pressurised gas cylinder:
Make sure that the disposable CO pressurised gas cylinder is completely empty. There should be no CO bubbles rising in the reactor or di user.
Disconnect the CO hose from the pressure regulator fitting and turn the pressure regulator counterclockwise o the Cylinder. Dispose of the empty
cylinder according to your local regulations. Connect a new cylinder as described in chap. 11.1.
Refillable CO pressurised gas cylinder:
Close the cylinder valve and disconnect the CO hose from the pressure regulator. Open the adjusting screw and release any pressure still present in
the pressure regulator until both pressure gauges indicate 0 bar. Loosen the connecting nut of the pressure regulator from the cylinder valve. Hand
over the reusable CO pressurised gas cylinder for refilling.
If there is no filled reusable CO pressurised gas cylinder available, you can also connect a disposable cylinder. Use the enclosed Allen key (size 6) to
remove the cylinder connection nut from the pressure regulator. The thread that comes free will fit the disposable CO cylinder.
Connect the filled reusable CO pressurised gas cylinder or the disposable CO pressurised gas cylinder as described in chap. 11.1.
