with the long pipe in the bubble counter. Open the bubble counter by a quarter turn (bayonet)
and fill with water to up the mark before closing again. The non-return valve (9) absolutely
must be installed before the bubble counter in the CO2 supply hose in the direction of flow
of the gas i.e. between the pressure reducer or, as applicable, the pH control and the bubble
counter. If this is not done, the water in the bubble counter may be sucked into the valuable
appliances and damage them.
For units u403, m603, m1003:
Select a suitable place to position the pH computer (7) where it can be easily observed.
Install the CO hose according to the illustration on the hose connection of the pH computer.

More details are to be found on the instructions for use enclosed separately.
5. For the CO storage cylinder select place with a stable base and out of the reach of children

(e.g. bottom cupboard of aquarium). Place the m500 (1) refillable storage cylinder onto the
stand. The m2000 (2) refillable storage cylinder and the disposable u500 (3) storage cylinder
are free-standing. Place the cylinder in the position selected.
6. Attach the pressure regulator fitting (for u402 and m602 with fitted solenoid valve) to the
storage cylinder:
Sets u401, u402, u403: Screw the pressure regulator fitting (5,6) with the reverse internal
thread briskly onto the external thread of the disposable storage cylinder (3). 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 now shows the
cylinder pressure of about 60 bar and the right-hand gauge shows the operating pressure of
about 1.5 bar. Close the adjusting screw clockwise if it is not already closed.
Sets m601, m602, m603, m1003: screw the connecting nut on the bottom of the pressure
regulator (4, 6) to the external thread of the cylinder valve on the m500 (1) and m2000 (2)
disposable cylinders. Firmly tighten the connecting nut with the enclosed spanner. Close the
adjusting screw clockwise if it is not already closed. Storage cylinders should lie flat or
upside-down when in use!! This may damage the pressure regulator!!
7. Attach the CO

valve (6).
8. Set u401:
Slowly open the adjusting screw on the pressure regulator and set a bubble rate of 10 – 15
bubbles in the bubble counter (approx. 15 – 20 bubbles in the reactor). At first the bubbles
will flow intermittently through the reactor, collecting at times into large bubbles. The device
needs approx. 48 hours to run in! After this time a bio-film will have formed on the surface
of the device, allowing the bubbles to rise freely upwards. After the necessary running in
time, set the bubble count for your aquarium, as described in Chapter 13.
Set m601:
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 set u401.
Sets u402 and m602:
First connect the power supply unit of the solenoid valve to a mains socket and connect the
12 V cable of the power supply unit with the cable of the solenoid valve. For u402 continue
as for u401 and for m602, as for m601. After the required number of bubbles have been
set for your aquarium (Chapter 13), connect the solenoid valve to the power supply which
is controlled by the time switch for the aquarium lighting. In this way the CO
