Assembly instruction (fig. 2)
First shut the CO supply. Push on the suc-
2
tion cups (1.2) at the top and the bottom if
you wish to use them for installing the bubble
counter. Fill the sera flore CO bubble count-
2
er entirely with water (immerse in the water
vertically). The bubble counter (2.1) is in-
stalled into the CO supply setup behind the
2
pressure reducer (2.2), between the non-re-
turn valve (2.3) and the CO reactor (2.4). Cut
2
the CO hose with a pair of scissors and in-
2
sert the water-filled bubble counter to do so.
The nozzle (1.3) is located at the bottom end.
Cover the top end of the bubble counter with
your index finger as to prevent water running
out of the bubble counter during installation.
Push the CO hose on the bottom end. Then
2
push the hose on the top end.
Operation
You can open the CO supply again and
2
adjust the desired number of bubbles after
the sera flore CO bubble counter has been
2
installed into the CO system. A part of the
2
liquid can run from the bubble counter into
the CO hose after switching off the CO sup-
2 2
ply. This is not a malfunction. The water will
be pushed back into the bubble counter after
switching the CO supply back on, making it
2
function properly again.
A part of the water may have evaporated after
longer operation. In that case take out the bub-
ble counter, fill it with water and install it again.
