11. Replacing the washer in the pressure reducer
The self-locking, maintenance-free Longlife washer in the connection socket
of the pressure reducer will normally function effectively over many years.
Should you be unable to produce a connection which does not leak despite
screwing on the pressure reducer several times (without canting!), the was-
her is presumably worn out and should be replaced.
• For this purpose, insert a small screwdri-
19
ver or similar behind the washer from
the side and carefully lever the washer
out. Be careful not to damage the
connecting thread, the pressure pin or
the sealing surface! Be sure to verify
that no foreign matter (dust, dirt particles, metal chips, etc.) enters into
the opening of the pressure reducer!
• Blow air through the connection socket in order to clean it.
• Carefully press the new washer into position using a suitable, non-metal-
lic object. Be careful not to damage the washer and the connection
socket. Check that the washer is fitted correctly in place.
12. Examining the special CO check valve
2
The check valve protects your valuable pressure reducer from corrosion cau-
sed by back-flowing water. It will operate reliably over a very long period.
However, as dirt, paint and metal particles may collect on the sealing sur-
faces over the course of time, the check valve should be examined every 2
years at the latest and replaced if necessary.
Examination procedure:
• Close needle valve on CO pressure reducer.
2
• After 24 hours, unscrew the coupling ring on the side of the check valve
facing the pressure reducer.
• Pull off CO hose and check whether any water has entered into the
2
hose. If so: Replace check valve. If not: Reconnect hose to check valve.
• Reset number of bubbles.
Don't worry: An effectively functioning aquarium will normally have no pro-
blem coping without a CO supply for 24 hours
2
Important note: Use only check valves designed for use with CO
the special CO check valve from DENNERLE. Standard air check
2
valves may become brittle through contact with CO within only a short
2
space of time, resulting in leaks. This usually goes unnoticed.
13. Replacing the special CO indicator
2
Like most colouring agents, the indicator is subject to ageing as a result of
photochemical processes. In order to guarantee the quickest and most exact
colour response at all times, we thus recommend filling the test container
with fresh special CO indicator every 4 weeks.
2
For this purpose, open the test container and pour the old indicator down
the drain. Rinse test container with tap water and dry with a kitchen cloth
or similar before refilling.
14. Cleaning the CO long-term test
2
Use warm water and a soft sponge. Do not use any cleaning agents!
The test container can be dismantled for cleaning. If necessary, grease the
two O-rings slightly (!) with Vaseline (from a pharmacy, drugstore) before
re-assembling the test container.
18
IMPORTANT: Do not use any other lubricants, as these may lead to incorrect
colour indications.
15. Cleaning the CO Flipper
2
20 • Take CO FLIPPER out of the aquarium.
2
• Extract CO collector vertically.
2
• Place CO Flipper into your left hand, so
21
2
that the suction cups point towards the
right. The open side (which holds the
collector) points upwards.
• Slide front side wall of the Flipper
upward by approx. 2 cm.
• Remove the side wall.
22
• Remove the CO
• Now clean all components of the CO
Flipper with warm water and a soft
sponge. Do not use any detergents.
23
• Reassemble the Flipper in reverse order.
Attention: reinsert the CO
side wall so that the lower end is at the
very bottom of the reactor.
