Operating instructions

Always observe the opera ting 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

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.

c = "Off" rotary switch
d = "Heating" rotary switch
e = green LED lit "Operation"
f = rotary knob for room temperature (1 – 5, 4 ≈ 23 ˚C)
g = red LED lit, red LED blinking "Failure"

Switching on the Heating

Turn on gas cylinder and open quick-acting valve in the gas
supply line.
Adjust desired room temperature at rotary knob.
Switching the heating on:
Set the rotary switch to (d).

Switching on the Ventilation

Set the rotary switch to (b).

Switching off

Set the rotary switch (a) to the centre (c). If the appliance is
switched off after a heating phase, the fan can continue run-
ning in order to make use of the residual heat.
If the appliance is not used for a prolonged period of time,
close quick-acting valve in the gas supply line and turn off
gas cylinder.

Green LED "Operation"

(under rotary control knob)
When the appliance is switched on (heating or ventilation)
the green LED must be illuminated (the fan is running). If the
LED is not illuminated, possibly check the (main) switch. For
this purpose observe respective instructions of the vehicle
manufacturer.
During the heating operation, while the flame is burning, the
green LED lights up with twice the intensity. This also makes
it possible to determine the instantaneous switching point of
the room temperature.

Fuses

The device and control panel fuses are on the electronic con-
trol unit on the device.
Device fuse (F1):
3.15 AT – slow –
Control panel fuse (F3):
1.6 AT – slow –
The fine-wire fuse must only be replaced by a fuse of the
same design.

Red LED "Failure"

Should a failure occur, the red LED is illuminated permanently.
Possible causes for the failure can be e.g. no gas, insufficient
combustion air, heavily soiled fan, defective fuse etc.. Deacti-
vate by switching off and then switching on again.
Flash operation indicates that the operating voltage is
too low (charge battery, if necessary) or too high for the
appliance.

Maintenance

The unit must be checked annually for contamination (dust,
dirt, debris) by an expert and cleaned if necessary.
Servicing shall be carried out only by authorised
