Inspection of the gas facilities
• Hae the gas facilities checked by an expert
before the rst use.
• The gas facilities should be inspected by
an expert every two years. This inspection
should be documented on the inspection cer-
ticate in accordance with the German Asso-
ciation of Gas and Water Experts, worksheet
G 607, and EN 1949.
• Regulator knobs, hoses and waste gas out-
lets should also be inspected.
• We recommend that you replace the safety
regulator knob and hose pipes fter 10 years at
the latest.
• The owner/operator is responsible for arran-
ging the inspection. This also applies for ve-
hicles that are not licensed to drive on public
roads.
Installations and modications
• Installations and modications may only be
conducted by an expert.
• Only devices with a uniform inlet pressure of
30 mbar may be operated.

• Only use those regulator knobs custom-made
for vehicles, with a safety valve. Other regula-
tor knobs are not permissible in accordance
with the German Association of Gas and Wa-
ter Experts, worksheet G 607, and EN 1949.
They are not sufcient to tolerate the im-
mense strain.
• Pressure regulators must have a xed output
pressure of 30 mbar. The requirements of EN
12864, Appendix D, apply accordingly. The
regulator must have a rate of ow of 1.2 kg/h.
