Installation
u001:
Screw the pressure regulator fitting with the reverse internal thread (b) briskly onto the external thread of the disposable
storage cylinder. After a few turns a brief hissing noise will be heard. Continue to turn briskly until resistance is felt. Then turn
about half a turn more until the fitting is hand-tight. The left-hand gauge (c) now shows the cylinder pressure of about 60 bar
and the right-hand gauge (d) shows the operating pressure of about 1.5 bar. Close the adjusting screw (f) clockwise if it is not
already closed.
Attach the CO
hose of your CO
system to the connection for a CO
hose (e) and adjust the amount of CO
as required

using the adjustment screw (f).
m001:
Screw the connecting nut on the bottom of the pressure regulator (a) to the external thread of the cylinder
valve on the disposable cylinder. Firmly tighten the connecting nut with a suitable spanner (SW 30).
Close the adjusting screw clockwise if it is not already closed. Open the cylinder valve of the refillable cylinder fully. The
left-hand gauge now shows the cylinder pressure of about 60 bar and the right-hand gauge shows the operating pressure
of about 1.5 bar. Continue as described for u001.
Operating pressure
The pressure in the storage cylinder is adjusted downwards by the pressure regulator to an easily manageable pressure,
known as the "operating pressure". The right-hand gauge (d) indicates this operating pressure. In the JBL pressure
regulator fittings u001 and m001 it is pre-set at about 1.5 bar. This is the optimum pressure for the CO
fertilization of
2
aquariums. If required, however, the operating pressure can be adjusted using the setting screw (g). When the operating
pressure is adjusted it is important that CO
is released i.e. the adjustment screw (f) should not be closed as this would

prevent adjustment of the pressure.
Changing cylinders
If the cylinder pressure (c) falls below 30 bar, the cylinder will need to be refilled (refillable cylinders) or changed (disposable
cylinders) in the next 2 – 3 days.
