Product description
4.2.1 Heating and hot water mode
All 3 energy options of the heater can be used�
In heating and hot water mode, the appliance auto-
•
matically selects the necessary operating level�
In electrical mode, 900 W (3�9 A) or 1800 W (7�8 A)
•
power can be selected manually in accordance with
the fuse protection at the campsite�
If more power is required (e�g� for heating up or at
•
low outside temperatures), select diesel or mixed
mode so that sufficient heating power is always
available�
In mixed mode, 230 V electrical mode is preferred
•
if the power requirement is low (e�g� for maintain-
ing the room temperature)� The diesel burner only
switches on when more power is required and is
the first to switch off when heating is in progress� If
no 230 V line power is available in mixed mode, the
control panel issues a warning and switches over to
diesel mode�
Avoid prolonged operation at the lowest level�
If possible, avoid continuous operation with low
room temperature requirements for a longer period
(longer than 10 days) in diesel mode, and use elec-
tric mode instead�
If it is not possible to switch to electric mode, the
heater should be briefly heated up once a day so
that condensation can evaporate and clean combus-
tion is possible�
Drain the water and switch off the heating during
longer periods of not using the heater, especially
during periods of frost�
4.2.2 Hot water mode (only with water container
filled)
Diesel or electrical mode is used to heat water�
 Mixed mode cannot be used to heat water� If mixed
mode is selected, the applianceautomatically selects
electrical mode� The diesel burner is not switched on�
Depending on the installed control panel, the tempera-
ture can be set to 40 °C, 60 °C or 70 °C� If you require a
lot of hot water, set the water temperature higher�
In electrical mode, 900 W (3�9 A) or 1800 W (7�8 A)
power can be selected manually in accordance with the
fuse protection of the line power connection�

4.3.2 Fuel at low temperatures
The refineries and filling stations will automatically per-
form the required adjustments for the usual winter tem-
peratures (winter diesel)�
Difficulties can occur at temperatures below 0 °C if the
vehicle still has summer diesel in its fuel tank�
Consider spare canisters with summer diesel�
At temperatures below -20 °C, check the suitability
of the winter diesel for this temperature range before
starting the heater�
Blends of waste oil, rapeseed oil, spirit or petrol are not
allowed�
To guarantee that all fuel lines of the heater unit are
filled with winter diesel or another permitted mixture
