u501, u502:
The left-hand pressure gauge now shows the bottle pressure of about 60 bar and the right-
hand pressure gauge shows the operating pressure of about 1.5 bar.
Close the adjusting screw by turning clockwise, if it is not already closed.
The m501, m502, m503, m2003 CO
Screw the connecting nut on the back of the pressure regulator (4, 6) onto the external
thread of the bottle valve on the m500 (1) or m2000 (2) refillable storage bottle. For the use
WITHOUT tools the connecting nut is designed as a knurled nut! Tighten it only by hand
without a tool. Close the adjusting screw by turning clockwise if it is not already closed.

u501, u504 kits:
6.
Slowly open the adjusting screw on the pressure regulator and set a bubble rate of 10
– 15 bubbles on 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, a bio-film will have formed on
the surface of the device, allowing the bubbles to rise freely upwards. After the running in
time, set the bubble count for your aquarium, as described in chapter 12.3.
The m501 kit:
Open the bottle valve of the refillable storage bottle all the way. The left-hand pressure
gauge now shows the bottle pressure of about 60 bar and the right-hand pressure gauge
shows the operating pressure of about 1.5 bar. Continue as described for kit u501.
The u502 and m502 CO
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 to the cable of the solenoid valve. For u502,
continue as described for u501, and for m502, as described for m501. After the required
number of bubbles have been set for your aquarium (chapter 12.3), connect the solenoid
valve to the power supply which is controlled by the time switch for the aquarium lighting.

Set up the pH computer, carrying out the calibrations required for initial start-up in ac-
cordance with the instructions for use enclosed separately. Make sure that the solenoid
valve of the pressure regulator is connected to the pH computer by the valve cable. Set
the integral solenoid valve to "man open": Menu key > select "Valve" > press OK > select
"man open"> press OK. For u503, continue as described for u501, and for m503 / m2003,
as described for m501. After the reactor has run in, set the control for the solenoid valve
to "auto": Menu key > select "Valve" > press OK > select "auto"> press OK. Then set the
optimum pH level for your aquarium and the required number of bubbles on the pH com-
puter as described in the instructions for use enclosed separately. The pH computer will
now automatically regulate the pH level and the CO
