Safety instructions
The unit may only be operated using appropriate Truma
control panels.
The use of upright gas cylinders from which the
gas phase
is
taken is mandatory when operating gas pressure regulation
systems, gas devices and gas systems. 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.
If the gas system is leaking or if there is a smell of gas:
– extinguish all naked flames
– open windows and doors
– close all quick-acting valves and gas cylinders
– do not smoke
– do not operate any electric switches
– have the entire system inspected by an expert!
Repairs may only be carried out by an expert!
Guarantee claims, warranty claims and acceptance of liability
will be ruled out in the event of the following:
– modifications to the unit (including accessories),
– modifications to the exhaust duct and the cowl,
– failure to use original Truma parts as replacement parts and
accessories,
– failure to follow the installation and operating instructions.
It also becomes illegal to use the appliance, and in some
countries this also makes it illegal to use the vehicle.
The operating pressure of the gas supply (30 mbar) must
correspond with the operating pressure of the unit (see type
plate).
Liquid gas systems must comply with the technical and ad-
ministrative regulations of the respective country of use (e.g.
EN 1949 for vehicles in Europe). The national legislation and
regulations (e.g. DVGW Work Sheet G 607 for vehicles in
Germany) must be observed.
In Germany, the gas system must be retested every 2 years by
a liquid gas specialist (DVFG, TÜV, DEKRA). The test must be
confirmed on the respective test certificate (G 607).
The vehicle owner is always responsible for arranging the
inspection.
Liquid gas equipment must not be used during fuelling, or in
enclosed car parks, in garages, or on ferries.
During the initial operation of a brand new appliance (or after
it has not been used for some time), small quantities of fumes
and a slight odour may briefly occur. It is a good idea to heat
the device up several times in summer mode (60 °C) and en-
sure that the area is well ventilated.
Heat-sensitive objects such as spray cans or flammable liq-
uids may not be stored in the same compartment where the
heater is installed because, under certain conditions, this area
may be subject to elevated temperatures.
Only pressure regulating equipment that complies with
EN 12864 (in vehicles) with fixed output pressure of 30 mbar
may be used for the gas system. The flow rate of the pressure
control device must correspond to at least the maximum con-
sumption of all devices installed by the system manufacturer.
We recommend the Truma gas pressure regulation system
MonoControl CS for vehicles and the gas pressure regulation
systems Truma DuoComfort / DuoControl CS for dual-cylinder
gas systems.
At temperatures of around 0 °C and below, the gas pressure
regulation system or the changeover valve should be operated
with the EisEx regulator heater.
Controller connecting hoses that meet national regulations
must always be used in the respective country for which the
equipment is destined. These hoses must be checked regu-
larly for brittleness. Winter-proof special hoses must always
be used if the equipment is operated during the winter.
Pressure regulating devices and hoses must be replaced with
new ones no more than 10 years after their date of manufac-
ture (every 8 years if used commercially). This is the responsi-
bility of the operator.
Important operating notes
If the cowl has been placed near or directly beneath an open-
ing window, the device must be equipped with an automatic
shut-off device in order to prevent operation with the window
open.
The integrity and tight fit of the exhaust gas double duct must
be checked regularly, particularly at the end of long trips. Also
check the mounting of the unit and the cowl.
Following a blow-back (misfire) always have the exhaust duct
checked by an expert!
Keep the cowl for the exhaust duct and combustion air intake
free of contamination (slush, ice, leaves etc.) at all times.
The warm air outlets and the circulated air intake openings
must be clear so that the unit does not overheat. The inte-
grated temperature limiter blocks the gas supply when the
unit becomes too hot.
Directive 2004/78/EC stipulates that a safety shut-off device is
required if motor homes are being heated while driving.
The gas pressure regulation system MonoControl CS satisfies
these requirements.
If
no
safety shut-off device (e.g. as contained within the
Truma MonoControl CS gas pressure regulation system)
has been installed, the gas cylinder must be closed when
driving and
information signs
must be attached in the gas
cylinder protection box and in the vicinity of the control panel
The safety shut-off device is also recommended for safety
reasons if caravans are being heated while driving.
