REPLACING CO
2
GAS BOTTLE
Safety instructions for using CO
2
gas cylinders.
Not following these instructions may lead to serious or fatal injuries!
Always connect the CO
2
cylinder to the
regulator. Never connect the cylinder
directly to the carbonator to avoid the
danger of bursting. Never unscrew
ttings from containers.
Always keep the cylinder away from
heat.
Only connect the CO
2
cylinder if:
• The gas cylinder location is sufciently
ventilated OR a CO
2
warning device
is installed. Always ventilate the area
after CO
2
leakage!
• The CO
2
cylinder is in an upright posi-
tion, secured well with the safety strap
and located at a safe distance (mini-
mum 50 cm) from any heat sources.
• It is proved that there is no liquid gas
escape.
• The required pressure regulator with
safety valve for the dispenser is avail-
able.
• The safety valve is sealed and fully
functional.
Danger! CO
2
is a colourless,
odourless gas. Danger of
suffocation.
• Observe the operating instructions
for handling CO
2
compressed gas
cylinders.
• Ensure that the CO
2
bottle size cal-
culated from the spatial volume of
the installation room is not exceed-
ed. Contact the customer service
in the case of questions about the
size of the CO
2
bottle
• In the case of a suspected increase
in CO
2
concentrations, do not
breathe in, exit the danger area
and sufciently ventilate the place
of installation.
• Dissipate the CO
2
in accordance
with the corresponding statutory
provisions.
• Always run hoses so that they
cannot come into contact with heat
sources, moisture, oil, sharp ob-
jects, sharp edges etc. Do not bend
or pinch hoses.
• Do not touch a frozen CO
2
bottle.
Danger to life from CO
2
bottle pressure! In the case of improper
handling, the pressure on the CO
2
bottle can lead to serious or even
fatal injuries. Before replacing the CO
2
bottle:
• Establish a pressureless state.
Also discharge residual energy.
• Always ensure that the unintended
escape of CO
2
is prevented.
• Have defective parts – to which
pressure would be applied during
normal operation – immediately
replaced by a trained person.
• Always secure CO
2
bottles in
an upright position and secure
against falling.
• Always observe the safety notes
on the CO
2
bottle.
12 steps to change the CO
2
cylinder safely:
1. CO
2
bottle is empty (check E2 for
the lling level of the CO
2
Bottle).
2. Close the CO
2
bottle valve A.
3. Release pressure from safety
valve D.
4. Release pressure regulator C by
unscrewing the connection nut
F (please keep in mind that it is
lefthand threaded).
5. Remove cylinder B. Secure it
upright.
6. Secure the new cylinder upright
with safety strap. Open protection
cap.
7. Open valve A once full to clear
outlet and close again.
8. Connect the pressure regulator C.
Make sure the sealing washer is
tted correctly.
9. Tighten nut F with spanner. En-
sure all connections are tightened.
Do not overtighten.
10. Close shut off valve G. Open valve
A. Close valve A. Check manom-
eter E2. The displayed pressure
gauge should stay stable when
you close valve A again.
11. Check for leakage with solution
of soapy water or an equivalent.
Appearing bubbles are a sign of
leakage. If leakage problem can
not be solved, contact the custom-
er service (see rear page). The
correct pressure applied to the de-
vice is 0.45 MPa / 4.5 bar (please
check manometer E1).
12. Open the CO
2
bottle valve A.
Open shut off valve G.
