Maintenance
The water container used is
made of stainless steel, which
is foodstuff-compatible.
Use wine vinegar for descal-
ing the water heater, this
being introduced into the ap-
pliance via the water supply.
Allow the product to react
and then thoroughly flush
out the appliance with plenty
of fresh water. To sterilise
the water we recommend
„Certisil-Argento". Other
products, particularly those
containing chlorine are
unsuitable.
To avoid infestation by micro-
organisms, the boiler must
be heated to 70°C at regular
intervals (only possible in
winter operation).
Do not use the water as
drinking water!
Fuses 12 V
The 12 V fuses for the device
are located on the electronic
control unit (12).
The fine-wire fuse must only
be replaced by a fuse of the
same design.
F1: 6.3 A, slow-acting
F2: 1.6 A, slow-acting
Fuse 230 V
The fuses and power connec-
tion cables must always be
replaced by experts!
Disconnect all poles
of the unit from the
mains before opening the
housing containing the power
electronics.
The 230 V fuse of the unit is
in the power electronics (13)
on the unit.
This fine fuse must always be
replaced with a fuse of the
same type: 10 A, slow, inter-
rupting capacity „H".

Overheating
protection 230 V
The 230 V heating facility
has a mechanical overheat-
ing switch. If the 12 V power
supply is interrupted during
operation or during the after-
run period, for example, the
temperatures within the unit
could trigger the overheating
protection.
To reset the overheating pro-
tection, let the heater cool
down, slide cover on power
electronics (13) upwards and
push in the red button.
Important operating notes
Always use original Truma
spare parts for maintenance
and repair work.
1. If the cowl has been
placed near or directly be-
neath an opening window,
the device must be equipped
with an automatic shut-off
device in order to prevent
operation with the window
open.
2. 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 mount-
ing of the appliance and the
cowl.
3. Following a blow-back
(misfire) always have the ex-
haust gas system checked by
an expert!
4. Always keep the cowl for
the exhaust duct and com-
bustion air intake free of con-
tamination (slush, ice, leaves
etc.).
5. The liquid gas burner oper-
ates fan-supported, which
ensures trouble-free function
even when on the move.
National restrictions must
be observed with regard to
operation when on the move.
6. The installed temperature
limiter shuts off the gas sup-
ply if the appliance becomes
too hot. Therefore do not
shut the warm air outlets and
the opening for the returning
circulating air.
7. The installer or vehicle
owner must apply the yellow
sticker with the warning in-
formation, which is enclosed
with the appliance, 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.
8. Directive 2004/78/EC stipu-
lates that a safety shut-off
device is required if motor
homes are being heated
while driving. The safety
shut-off device is also recom-
mended for safety reasons
if caravans are being heated
while driving.
The Truma SecuMotion gas
pressure regulator meets this
requirement.
If no Truma SecuMotion
gas pressure regulator
is installed, the gas cylinder
must be closed whilst driving
and information signs must
be attached to the cylinder
cabinet and in the vicinity of
the control panel.
