Safety Instructions; Important Operating Notes - Truma Combi 4 Gebrauchsanweisung

Safety instructions

The use of upright gas cylinders from which gas is taken in
the gas phase is mandatory for the operation of gas regula-
tors, gas equipment 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 open flames
– open windows and door
– close all quick-acting valves and gas cylinders
– do not smoke
– do not activate any electric switches
– ask an expert to inspect the entire system!
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 even makes it illegal to use the vehicle.
The gas supply's operating pressure (30 mbar) must be the
same as the unit's operating pressure (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 may not be used when refueling, in
multi-storey 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), a slight amount of fumes
and smell may be noticed for a short while. It is a good idea to
heat the device up several times in summer operation (60 °C)
and to make sure that the area is well ventilated.
Heat-sensitive objects such as spray cans or flammable liquids
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 gas pressure control systems Truma
SecuMotion / MonoControl CS for vehicles and the gas pres-
sure control systems Truma DuoComfort / DuoControl CS for
dual-cylinder gas systems.
At temperatures of around 0 °C or less the gas pressure regu-
lator and the changeover valve should be operated using 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 equipment and hoses must be replaced
with new ones no more than 10 years after the date of
manufacture (every 8 years if used commercially). This is the
responsibility 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 appliance and the cowl.
Following a blow-back (misfire) always have the exhaust gas
system checked by an expert!
Always keep the cowl for the exhaust duct and combustion air
intake free of contamination (slush, ice, leaves etc.).
The hot air outlets and the recirculated air intake openings
must be free so that the unit does not overheat. The integrat-
ed 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 Truma gas pressure control systems SecuMotion /
MonoControl CS satisfy these requirements.
If no safety shut-off device (e.g. for the gas pressure
control system Truma SecuMotion / MonoControl CS)
has been installed, the gas cylinder needs to be closed when
driving and appropriate signs must be displayed in the gas
cylinder protection box and close to the control panel.
The safety shut-off device is also recommended for safety
reasons if caravans are being heated while driving.
