Operating The Fan; Lighting; Room Thermostat; Switching Off - Truma S 3004 Gebrauchsanweisung

Should the flame go out during operation, immediate re-ig-
nition takes place within the closing time of the safety pilot
(approx. 30 seconds).
If a flame is not produced, the auto ignitor continues to work
until "0" is switched on the control knob (a).
If the gas supply line is filled with air, it can take up to two
minutes until the gas is ready to burn. Keep the control knob
pressed down during this time until the flame burns.
3. In order to achieve even and quick distribution of warm air
and reduction of the surface temperature at the outlet grill for
warm air, we recommend that the heating system is operated
with the Truma warmer running.

Operating the fan

a = Control knob / scale for fan power (1 – 5)
b = Rotary switch / scale for operating modes
A Automatic – The electronics regulate the
required fan output and limit the
speed to the set value.
0 OFF – Switch off fan.
M Manual – Set the required fan level.
Booster level – Set the fan power to the highest
value (for maximum air volume
current).

Lighting

The lighting (optional) for the panels is activated by a proxim-
ity switch. Touch from above on the middle of the cover. This
means that the lighting is switched on for approx. 20 seconds.
Each time the 12 V voltage supply is produced, the
sensor electronics calibrate the lighting. This can take
several seconds. Do not touch the cover during calibration.

Room thermostat

An average room temperature of approx. 22 °C is achieved
with a thermostat setting of approx. 3 without operating
the fan. We recommend operation with a fan and a thermo-
stat setting of approx. 4 for comfortable warm air distribution
and for reduction of condensation on cold surfaces.
The exact thermostat setting must be established correspond-
ing with the construction type of the vehicle and according to
the individual warmth requirement.

The thermostat sensor is on the bottom of the heating
system. Please note that the cold draughts caused by re-
frigerator ventilation, gaps in doors or a high pile carpet can
have a negative influence on the thermostat. Such sources of
disturbance are to be addressed in all cases otherwise a satis-
factory temperature control is not guaranteed.

Switching off

Set the control knob on the heating system to "0" (the auto
ignitor is simultaneously switched off).
Switch off fan (set rotary switch to "0").
If the device is not used for a longer period, close the quick-
acting valve in the gas supply line and gas cylinder.

Maintenance

Always notify the Truma Service Centre or one of our author-
ised service partners if problems are encountered (see Truma
Service book or www.truma.com).
Despite careful production, the heating system can
contain parts with sharp edges, therefore always wear
protective gloves for maintenance and cleaning work!
Observe the ESD-regulations!
There is a risk of damage to the electronics due to static
charge. Only experts may carry out repair work!

Cleaning (only with the device switched off!)

It is recommend to remove the dust that has collected on
the heater exchanger, floor plate and on the fan wheel on the
Truma warm air system at least once per year at the beginning
of the heating season. Carefully clean the fan wheel with a
paint brush or small brush.

Remove cover

Only remove the cover with the heating switched off
and cold.
By simultaneously pressing both closure levers (1) outwards,
the cover is unlocked. It can be pivoted out and lifted out of
the lower bearings.
