Regulators and valves
• Use only special vehicle regulators that have a safety valve.
In accordance with the German DVWG (German Associa-
tion of the Gas and Water Sector) Worksheet G 607, other
regulators are not permitted; they are not adequate for
handling the heavy strain.
• Pressure governors must have a xed pressure of 30 mbar.
The regulations of EN 12864, Appendix D apply accor-
dingly. The pressure governors must have a minimum ow
rate of 1.2 hx/h.
• Attach the high-pressure hose on the bottle carefully by
hand (note: left-handed thread). Do not use spanners,
pliers or similar tools.
• If the temperature is below 5°C use the de-frosting facility
(ice-ex*) for regulators.
Gas regulator for France and Great Britain *
Due to specic country regulations, the gas regulator in
vehicles exported to France and Great Britain is mounted on
the wall of the gas bottle container. The requires the use of a
high-pressure hose. Therefore, the low-pressure hoses that
are normally used may not be tted here.

This must be taken into account should it be necessary to
replace the hose.
Connections on gas pressure regulators are screwed on
counterclockwise.
