Operation manual ENG
For controlling the CO
2
supply in aquaria
The
Aqua Medic
M-ventil Eco
is a product of highest quality, safe and reliable for more pleasure with your
aquarium. A time dependant CO
2
supply can be realized using a timer together with this valve.
The solenoid valve may also be monitored via a pH controller to achieve a maximum degree of comfort with
ideal carbon dioxide provision at all times.

2. Operation with carbon dioxide (CO
2
)
Set-up:
The solenoid valve is pre-mounted and tested. It has only to be integrated into the CO
2
–system. On the body of
the valve, the direction of the flow is marked by No. 1.
At first, the hose is mounted on the
inlet (4):
1. Unscrew the knurled nut of the CO
2
connection (4).
2.
Push the knurled nut over the flexible pressure tube (6/4 mm, ¼“).
3.
Push the end of the tube over the nipple (4).
4.
Screw the knurled nut onto the nipple and tighten it.
5.
Mount the other end of the flexible tube onto the pressure outlet of the pressure reducer and tighten it.
6.
Now, a tube is mounted in the same way on the outlet (5). Here, you do not need to use a pressure tube,
you may use ordinary PVC-tube (6/4 mm, ¼“).
7.
The free end is connected to the bubble counter inlet or to the CO
2
–inlet.
8.
If you use a pressure regulator with adjustable operating pressure, set it to 1 bar.
Note:
Always use a non-return valve between the aquarium and solenoid valve. It prevents water from flowing
back from the aquarium into the regulator and the CO
2
–bottle and may cause damage. We recommend
to use the original Aqua Medic bubble counter with integrated non-return valve.
