5 Care and maintenance

5.1 Replace the CO cylinder
2
• Empty cylinder: Close cylinder valve. Unscrew coupling ring
using 27 mm spanner and screw pressure reducer onto refilled
reusable CO cylinder. Open cylinder valve The bubble count
2
setting will be retained.
• Full cylinder: Close cylinder valve. Turn setting knob of pressure
reducer towards " + " as far as it will go, in order to release any
residual pressure in the pressure reducer (if a solenoid valve is
connected, it must be open for this purpose). Unscrew coupling
ring using 27 mm spanner and screw pressure reducer onto re-
filled reusable CO cylinder. Open cylinder valve Reset number
2
of bubbles.
• Always close the cylinder valve in order to shut down the CO
supply for a prolonged period. Unscrew the pressure reducer
when the cylinder is to remain out of use for a prolonged period.
5.2 Testing the CO backflow check valve
2
The check valve protects your valuable pressure reducer/solenoid
valve from corrosion caused by back-flowing water. As dirt particles
may collect on the sealing surfaces over the course of time, the back-
flow check valve should be checked at least once a year and replaced
every 2-3 years for safety's sake.
Tip: Install a transparent test hose temporarily between backflow
check valve and pressure reducer/solenoid valve and shut down the
CO supply for 24 hours (close pressure reducer/solenoid valve). If
2
there is water in the test hose after this 24-hour period, this indicates
a leak on the backflow check valve.
The opening of the check valve can only be tested with CO
nimum pressure of approx. 0.3 bar is required to open the valve. It
is not possible to "blow through" the valve with your mouth.
Important note: Use only check valves designed for use with CO
as the special CO check valve from Dennerle. Standard air check val-

5.3 Replacing the washer
6
• We recommend replacing the washer (art. no. 3056) in the adapter
7
for connection to reusable cylinders on a regular basis, in order
8
9
to rule out leaking cylinder connections at all times.
1
• There is a Longlife washer in the connection socket of the pressure
11
reducer. It is not normally necessary to replace this washer du-

ring the service life of the pressure reducer. The seal can only be
14
replaced using special tools: Please send in the pressure reducer
to Dennerle's Customer Service department.
5.4 Cleaning and recalibrating the needle valve
There is a factory-calibrated needle valve in the hose connector of the
pressure reducer.
Should no CO be supplied although the cylinder is full and the setting
2
knob is turned to fully open position, this indicates that the needle
valve is probably blocked. In this case:
• Open the valve by turning by one half-turn in anti-clockwise di-
rection using a fine screwdriver (blade format 2 – 2.5 x 0.5 mm),
then "flush" with CO
fully open position.
Important: Do not unscrew valve completely ©
• Close valve again by one half-turn.
• The valve is factory-set to approx. 120 bubbles per minute when
2
the setting knob is in fully open position. If necessary, it can be
recalibrated by carefully screwing it in or out in steps of approx.
1/8 of a turn.
5.5 Removing the CO

To remove the hose, it is best to lever it off using a small screwdriver.

this may cause damage to the hose connectors ©
