Safety instructions
In the event of a leak in the heater or the exhaust duct:
– use the rotary switch to switch off heater,
– open windows and door,
– 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.
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.
The system must comply with the respective regulations of
the country in which it is used. National regulations and rules
must be followed.
Absolutely no objects (e.g. spray cans) or flammable liquids
are to be stored in the installation room or on the heater unit,
since they may be exposed to increased temperature levels
under certain conditions.
The exhaust system must be inspected by a qualified techni-
cian at regular intervals, not exceeding two years.
No work must be carried out on the heater, the exhaust duct
or in the vicinity of the chimney while the unit is in operation.
Do not inhale exhaust fumes.
Before performing any work on the heater or the exhaust duct,
switch off the heater and allow all parts to cool completely.
The heater must not be used during fuelling, or in enclosed
car parks, in garages, or on ferries.
Do not operate the heater anywhere where flammable va-
pours or dust can form, e.g. in the vicinity of a fuel, carbon,
wood or cereal storage facility or similar.
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 exhaust gas double duct (exhaust gas silencer and suc-
tion pipe) must be inspected regularly, particularly following
long journeys, to check for any damage and to ensure that the
connection is sound; the same applies to the mounting of the
heater and the cowl.
The cowl and the combustion air infeed must be kept free of
dirt (e.g. snow sludge, ice, foliage, etc.) at all times.
The hot air outlets and circulating / exhaust air intake openings
must be unobstructed, to ensure that the heater is not at risk
of overheating. The built-in temperature limiter blocks off the
fuel supply when the heater becomes excessively hot.
Even outside the season, the heater should be operated once
a month for about ten minutes.
When operational, the fuel display in the fuel tank must
not be allowed to drop to the "low fuel" mark.
In the event that the vehicle fuel tank runs empty, the
opening of the fuel removal duct is roughly at the same
height as the surface of the fuel. In this state, and in par-
ticular when the fuel in the vehicle fuel tank slops around
due to vehicle movement, a large amount of air is sucked
in. This leads to an irregular supply of fuel to the heater.
The heater burner is unable to maintain clean combus-
tion in this condition, leading to the formation of smoke
and odours.
A diesel heating system always needs more power than a
similar gas heating system. If there is a requirement for an
autarky of the same length (service life without external power
supply), Truma recommends investigating whether it is pos-
sible to retrofit a larger and / or second battery.
Fuel supply
Fuel quality
The heater requires diesel fuel for its operation, as per
DIN EN 590. Operation with biodiesel is not permitted (PME,
RME or AME).
Fuel at low temperatures
The refineries and filling stations will automatically perform
the required adjustments for standard winter temperatures
(winter diesel).
Temperatures below 0 °C can create difficulties if the vehicle
still has summer diesel in its fuel tank.
If no special diesel fuel is available for use in low tempera-
tures, e.g. winter diesel, then petroleum or benzine should
be mixed in with the fuel, in accordance with the instructions
given by the vehicle manufacturer.
Temperature
0 °C to -20 °C Winter diesel
-20 °C to -30 °C Polar or Arctic diesel
Used oil should not be used in a fuel mixture!
To guarantee that all fuel lines of the heater unit are filled with
winter diesel or another permitted mixture after fuelling, the
heater must be operated for at least fifteen minutes.
