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.
• Connect the regulator knob or high-pressure hose to the
bottle carefully by hand (NB: 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.

Due to specic country regulations, the gas regulator in vehi-
cles exported to France and Great Britain is rmly mounted
on the ceiling 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.
