Safety Instructions - Truma DuoControl Gebrauchsanweisung

An automatic PRV* safety device integrated in the DuoControl
with limited flow protects the connected consumers against
impermissibly high pressure. As soon as an impermissibly
high pressure arises on the output side, the PRV opens and
blows out the overpressure into the air. The PRV closes auto-
matically after the pressure is reduced
* = Pressure Relief Valve

Safety instructions

– The use of upright gas cylinders from which gas is extracted
in the gas phase is mandatory when operating the DuoControl
gas pressure regulation system. Gas cylinders from which
gas is taken in the liquid phase (e.g. for fork lifts) must
not be used, since they would result in damage to the gas
system.
– High-pressure hoses are required for connecting the gas
cylinders to the gas pressure regulation system. Truma
provides the necessary high-pressure hoses with the most
commonly-used connection variants for European gas cylin-
ders (see Page 80).
Even though it is not always a mandatory requirement,
Truma always recommends the use of high-pressure
hoses with hose rupture protection (HRP).
– Pressure regulation devices and hoses must be replaced
with new ones no more than 10 years after their date of
manufacture (every 8 years if used commercially). The oper-
ator is responsible for this.

Notes on operating the gas system while driving:
– The device manufacturer's instructions must be followed be-
fore operating a liquid gas device while driving.
– For heating while driving, the regulation (EC) No. 661/2009
and the binding UN/ECE regulation R 122 stipulate a safety
shut-off device for motor homes and caravans.
The Truma DuoControl CS gas pressure regulation system
satisfies this requirement.
Installing a safety shut-off device such as the Truma
DuoControl CS gas pressure regulation system with appro-
priately configured gas installation means that a type-tested
liquid gas heater may be used in line with the aforemen-
tioned regulation while driving throughout Europe. National
regulations and rules must be followed.
– For vehicles manufactured before 01/2007 there are no re-
strictions for operating the gas system while driving**. The
enclosed stickers (close gas cylinders while driving) are not
used in this case.
** Except for France:
In France, operation of a gas system while driving is only
permitted in type-tested vehicles with first registration as of
01.01.2007. In older vehicles operation of the gas system
while driving is also not permitted in combination with a
safety shut-off device.
Gas cylinders that are not connected to the gas installation
must be closed at all times and provided with protection caps.
Connected gas cylinders are considered to be operating mate-
rials and not hazardous materials (ADR exemption in accord-
ance with sections 1.1.3.1 and 1.1.3.2 e).
