Always observe the operating instructions and “Impor-
tant operating notes” prior to starting!
The vehicle owner
is responsible for the correct operation of the appliance.
The installer or vehicle owner must apply the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, to a place in the vehicle where it is clearly visible to
all users (e.g. on the wardrobe door)! Ask Truma to send you
stickers, if necessary.
Before using for the first time, it is essential to flush the
entire water supply system through with clean water. If
the heater is not being used, always drain the water contents
if there is a risk of frost.
There shall be no claims under
guarantee for damage caused by frost!
Materials in the device which come into contact with water
are suitable for use with drinking water (see manufacturer
declaration: www.truma.com – Manufacturer Declaration).

a = Power selection rotary switch
b = Electric operation 230 V, 1800 W
c = Electric operation 230 V, 900 W
d = Gas operation
e = Mixed operation* (900 W gas and electrical operation)
f = Mixed operation* (1800 W gas and electrical operation)
g = Yellow LED on = “Electrical operation”
* Winter mode only!
In summer mode the unit automatically selects electric opera-
tion at the preselected electrical power of 900 W or 1800 W.
Switching on the electric heating elements as well
does not increase the maximum heating power.

Operating instructions
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 gas pressure regulation system MonoControl CS satisfies
these requirements.
If
no
safety shut-off device (e.g. enclosed like in the gas
pressure regulation system Truma MonoControl CS) has
been installed, the gas cylinder needs to be closed when driv-
ing and
appropriate signs
must be displayed in the gas cylin-
der 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.
