! Note containing information and tips.
Intended use
MonoControl is a pressure regulator for caravans and motor homes. The gas
pressure regulator ensures a uniform output pressure of 30 bar with a
permissible inlet pressure range of 0.3 – 16 bar.
The MonoControl gas pressure regulator 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 110 bar.
Using the MonoControl 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 into the MonoControl 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.

MonoControl 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 gas pressure regulator. Gas
cylinders from which gas is taken in the liquid phase (e.g. for forklifts)
must not be used, since they would result in damage to the gas system.
– A gas filter must be installed upstream of the gas pressure regulator 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 is mandatory for connecting the gas cylinder to the gas
pressure regulator or gas filter. For this, Trump provides the necessary high-
pressure hoses with the most commonly used connection variants for European
gas cylinders (see www.truma.com).
– In normal conditions of use, in order to ensure the correct operation of the
installation it is recommended that this device is changed within 10 years of
the date of manufacture. National regulations must be observed. The operator
is responsible for this.
– 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 materials and not hazardous materials (ADR
exemption in accordance with sections 1.1.3.1 and 1.1.3.2 e).
The gas system must not be used while driving.

Reset button
MonoControl has a reset button, the position of which indicates its status:
“ready for operation” position (Figure 2a) or “not ready for operation”
position (Figure 2b).
To reset, press the reset button (6) firmly and turn it anticlockwise as far
as it can go. Ensure that the reset button (6) remains in the position “ready
for operation” (Figure 2a).
The Torx T20 (10) from the screw aid (9) or a Torx screwdriver can be used to
assist with the turning movement.
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).
– If the reset button (6) is not pressed (“not ready for operation” position),
press the button.
Changing the gas cylinder
Use the included screw aid (9) to attach and remove the high-pressure hose
(3). It will help you generate the necessary tightening torque and will
prevent damage to the union that may otherwise result from using an improper
tool.
Residual gas: No smoking, no naked flames!
– Close the valve (1) of the empty gas cylinder (2).
– Remove the high-pressure hose (3) 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).
! After any intervention, check the hose connection to the cylinder valve
for leaks (see “Checking for leaks in the high-pressure section”).
Hose change
Use the included screw aid (9) to attach and remove the high-pressure hose
(3). It will help you generate the necessary tightening torque and will
prevent damage to the union that may otherwise result from using an improper
tool.
Residual gas: No smoking, no naked flames!
– Close the gas cylinder valve (1).
– Unscrew the high-pressure hose (3) from the gas cylinder (2 / or the clip-on
adapter) and from the gas filter / MonoControl inlet.
When changing the hose, ensure that the seal provided with the hose (hose
outlet – gas filter/gas pressure regulator inlet) is correctly installed and
is not damaged.
! We recommend that you replace the flat gasket G 13 (part no.
50020-76300) every time the hose is changed.
– Screw the country-specific high-pressure hose (3) to the gas filter (4) /
MonoControl inlet and to the cylinder (2 / or the clip-on adapter).
– Open the cylinder valve (1).
– After any intervention, check the hose connection on the cylinder valve and
at the gas filter / MonoControl inlet for leaks (see “Checking for leaks in
the high-pressure section”).
Checking for leaks in the high-pressure section
The screw joints of the high-pressure hose at the gas cylinder valve and on
the gas filter/MonoControl 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
bar) The test must be conducted by a technician.
The gas hose and gas cylinder must be connected.
– Turn off all consumers.
– Open stop valves and, if present, the gas remote switch.
– Use the Torx T20 (10) from the screw aid (9) to turn the reset button
clockwise to the “not ready for operation” position.
– Remove the screw cap (8) from the test connection and connect the test pump
with test hose to the test connection.

– Check for leaks (e.g in Germany in accordance with G 607).
– If there is a gas system leak, close the cylinder valve, have the gas system
repaired by an expert immediately, and do not open the valve in the meantime.
– Unscrew the pump from the test connection and screw the screw cap (8) back
onto the test connection.
– It is essential to reattach the screw cap (8) every time after it has been
removed.
– Reset the reset button.
To reset, press the reset button (6) firmly and turn it slightly
anticlockwise. Ensure that the reset button (6) remains in the position “ready
for operation” (Figure 2a).
! The Torx T20 (10) from the screw aid (9) can be used to assist the
turning movement.
Maintenance
The MonoControl gas pressure regulator is maintenance-free.
The vehicle owner must arrange for the gas system to be tested in accordance
with the relevant national regulations (e.g. in Germany every 2 years) by a
liquid gas expert. The test must be confirmed on the respective test
certificate (G 607).
In countries where testing is not mandatory, we recommend that the gas system
be tested every 2 years for your own safety.
The filter pad in the gas filter must be replaced every time the gas cylinder
is replaced (see gas filter operating instructions).
