1. FUNCTIONAL TEST OF GAS PRESSURE
REDUCER
1. Screw the gas pressure reducer to the CO
2
cylinder
(not included in the pack). The connection is flat and
requires no additional sealing. If necessary, tighten the
hand wheel with a suitable wrench.
2. Close the shut-off valve (
A
, transverse to the direction
of flow).
3. Open the pressurised gas cylinder valve and close it
again (
C
).
4. Check for leaks.
5. Open the pressurised gas cylinder valve again (
B
).
6. Use the hexagonal regulator (
C
) to set the working
pressure to approx. 3.5 bar (
D
) – green mark.
7. Use the hexagonal regulator (
C
) to increase the pres-
sure to 7 bar – red mark (
D
).
8. Use the hexagonal regulator (
C
) to slowly increase the
pressure gradually until a slight blow-off begins.
9. Use the hexagonal regulator (
C
) to increase the pres-
sure further until the safety valve opens fully with a
loud noise. Observe the pressure gauge (
D
) this should
not exceed a value of approx. 7.7 bar.
10. Close the pressurised gas cylinder valve (
B
) immedi-
ately afterwards and turn the hexagonal regulator (
C
)
back to 0 bar to prevent icing.
11. Open the pressurised gas cylinder valve (B) again and
set to the right working pressure of 3.5 bar.
