Symbols used
The unit may only be installed and repaired by
an expert. Experts are persons who, based on
their specialist instruction and training, their
knowledge and experience with Truma products
and the relevant standards, can carry out the
necessary work properly and identify potential
hazards.
Symbol indicates possible hazards.
Note containing information and tips.
Intended use
MonoControl CS is a safety gas pressure regulator for caravans and mo-
tor homes. The gas pressure regulator ensures a uniform output pressure
of 30 mbar with a permissible inlet pressure range of 0.3 – 16bar.
The integrated crash sensor (CS) interrupts the flow of gas in the
event of an accident with directly acting deceleration of 4.0
g
± 1.0
g
.
The MonoControlCS gas pressure regulator with safety valve is a
single-stage gas pressure regulator. If the gas pressure regulator is
not working properly, for example due to dirt or other foreign material
on the valve, the safety valve opens and blows off to a pressure of
110mbar.
4EN
Using the MonoControl CS in closed rooms (e.g. at home), on boats
or in EX Zone 0 (e.g. tankers) is prohibited.
The national regulations must be observed if there is a possibility of it
being used in mobile homes. Its use in mobile homes is prohibited in
Germany.
An automatic PRV* safety device integrated in the MonoControl CS
with limited flow protects the connected consumers against imper-
missibly high pressure. As soon as an impermissibly high pressure
arises on the output side, the PRV opens and blows out the overpres-
sure into the air. The PRV closes automatically after the pressure is
reduced.
* = Pressure Relief Valve
MonoControlCS must not be used for commercial purposes.
Safety instructions
– Do not connect any electrical appliances or other potential ignition
sources if you can smell gas or if there is a leak in the gas system.
Close the cylinder valve, have the gas system repaired by an expert
immediately and do not open the valve in the meantime.
– The use of upright gas cylinders from which gas is extracted in
the gas phase is mandatory when operating the MonoControl CS
gas pressure regulator. 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.
5EN
– A gas filter must be installed upstream of the gas pressure regula-
tor inlet to provide reliable protection against dirt / oiling. A set of
operating and installation instructions is supplied with the gas filter.
– A high-pressure hose with hose rupture protection (HRP) is manda-
tory for connecting the gas cylinder to the gas pressure regulator or
gas filter. For this, Truma provides the necessary high-pressure hos-
es with the most commonly-used connection variants for European
gas cylinders (see www.truma.com).
– In normal conditions of use, in order to ensure correct operation of
the installation it is recommended that this device is changed with-
in 10 years of the date of manufacture. National regulations must
be observed. The operator is responsible for this.
Operating the gas system while driving:
– The appliance manufacturer’s instructions must be followed before
operating a liquid gas appliance 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 MonoControl CS gas pressure regulator satisfies this require-
ment.
Installing a safety shut-off device such as the MonoControl CS gas
pressure regulator with appropriately configured gas installation
means that a type-tested liquid gas heater may be used in line with
the aforementioned regulation while driving throughout Europe.
National regulations and rules must be followed.
6EN
– For vehicles manufactured before 01/2007 there are no restrictions
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 the operation of the gas system while driving is also
non-permissible 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. Connect-
ed gas cylinders are considered to be operating materials and not
hazardous materials (ADR exemption in accordance with sections
1.1.3.1 and 1.1.3.2 e).

Start-up
– Open the gas remote switch if present.
– Connect the gas cylinder (2) and ensure that the hose connection is
in perfect condition.
– Open the cylinder valve(1).
– Firmly press the hose rupture protection (figure1a–3) on the
high-pressure hose for about 5 seconds.
8EN
– If the yellow reset button (7) is not pressed (“not ready for opera-
tion” position), reset the crash sensor.
Crash sensor
The crash sensor has a reset button, the position of which indicates
its status: “Ready for operation” position (Figure2a) or “not ready for
operation” position (Figure2b).

Figure 2a Figure 2b
To reset, press the yellow reset button (7) firmly, turn it slightly clock-
wise, hold it for 5 seconds and ensure that it stays in the “ready for
operation” position (Figure 2a).
If the reset is not successful, use the Torx T20(12) on the screw aid (11)
to support the clockwise rotation.
Changing the gas cylinder
Use the included screw aid (11) to attach and remove the high-pres-
sure hose (4). It will help you generate the necessary tightening
torque and will prevent damage to the union that may otherwise re-
sult from using an improper tool.
Residual gas: No smoking, no naked flames!
9EN
– Close the valve (1) of the empty gas cylinder (2).
– Remove the high-pressure hose (4) from the gas cylinder (2) and
remove the clip-on adapter, if present.
– Attach the high-pressure hose to the full gas cylinder and fit the clip-
on adapter, if present. Change the filter pad of the gas filter.
– Open the full gas cylinder’s valve (1).
– Press the hose rupture protection (figure1a–3) and if necessary
the yellow reset button (7), turn it slightly clockwise and hold it for
5seconds.
After any intervention, check the hose connection to the cylin-
der valve for leaks (see “Checking for leaks in the high-pressure
section”).
Hose change
Use the included screw aid (11) to attach and remove the high-pres-
sure hose (4). It will help you generate the necessary tightening
torque and will prevent damage to the union that may otherwise re-
sult from using an improper tool.
Residual gas: No smoking, no naked flames!
– Close the gas cylinder valve (1).
– Unscrew the high-pressure hose (4) from the gas cylinder (2 / or the
clip-on adapter) and from the gas filter / MonoControl CS inlet.
10 EN
When changing the hose, ensure that the seal provided with
the hose (hose outlet – gas filter / regulator inlet) is correctly
installed and not damaged.
We recommend that the flat gasket G 13 (part no. 50020-76300)
be replaced every time the hose is changed.
– Screw the country-specific high-pressure hose (4) to the gas filter(5)/
MonoControl CS inlet and to the cylinder (2 / or the clip-on adapter).
– Open the cylinder valve(1).
– Press the hose rupture protection (figure1a–3) and if necessary
the yellow reset button (7), turn it slightly clockwise and hold it for
5seconds.
– After any intervention, check the hose connection on the cylinder
valve and at the gas filter / MonoControlCS inlet for leaks (see
“Checking for leaks in the high-pressure section”).
Checking for leaks in the high-pressure section
The screw joint of the high-pressure hose at the gas cylinder valve
and on the gas filter / MonoControl CS must be checked for leaks
using suitable means such as a leak-finder spray in accordance with
EN 14291. The operator is responsible for this.
Checking for leaks in the low-pressure section
(maximum test pressure 150 mbar)
