Safety Instructions - Truma DuoControl CS Gebrauchsanweisung Und Einbauanweisung

The national regulations must be observed if there is a possi-
bility of it being used in mobile homes. In Germany, its use in
mobile homes is prohibited.
An automatic PRV* safety device integrated in the
DuoControl CS 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 automatically after the pressure is reduced

Safety instructions

– The use of upright gas cylinders from which gas is ex-
tracted in the gas phase is mandatory when operating
the DuoControl CS 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 with hose rupture protection (HRP)
are essential for connecting the gas cylinders to the gas
pressure regulation system. Truma provides the necessary
high-pressure hoses with the most commonly-used connec-
tion variants for European gas cylinders (see Page 79).
– 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.

Operating the gas system while driving
– The device manufacturer's instructions must be followed
before 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-test-
ed liquid gas heater may be used in line with the afore-
mentioned 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**.
** 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 operat-
ing materials and not hazardous materials (ADR exemption
in accordance with sections 1.1.3.1 and 1.1.3.2 e).
