Operating the fan
a - Control knob / scale for fan power (1-5)
b - Rotary switch / scale for operating modes.
A - Automatic - The electronics control the
necessary fan power and limits the speed.
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).
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 thermostat
setting of approx 4 for comfortable warm air
distribution and for reduction of condensation
on cold surfaces.
The exact thermostat setting must be
established corresponding with the
construction type of the vehicle and according
to the individual warmth requirement.
Note: The thermostat sensor is on the
bottom of the heating system. Please note
that the cold draughts caused by refrigera-
tor 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 satisfactory 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 ‘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
In Germany, the Truma Service Center is
generally to be notified in case of any faults;
the respective service partners are available
in other countries (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!
The electronics can be damaged by the
danger of electrostatic charge. Only experts
may carry out repair work!
Cleaning
(only with the device switched off!)
It is recommended 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
! WARNING: 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.
