Technical Data
Unless tolerances are shown within the technical data
table, a tolerance of 10% applies at an ambient tempera-
ture of +20°C and at the rated voltage and conditions.
Electrical Components:
Control unit, motor, fuel metering pump, light bulb in the
digital timer* and pencil-type glow plug are designed either
for 12-volt or 24-volt operation.
The digital timer*, temperature limiter and flame detector
are voltage-independent components.
* Presetting of heater operating times is not possible for
ADR-operation
Fuel for AT 2000 S-B (Petrol):
The fuel specified by the vehicle manufacturer is suitable
as fuel for the heater.
Fuel for AT 2000 S-D (Diesel/Fuel Oil EL):
The Diesel fuel specified by the vehicle manufacturer is
suitable as fuel for the heater. Also EL class fuel oil – not,
however, L type fuel oil – can be used provided it conforms
to the usual quality on the German market in accordance
with DIN 51603.
Any negative effect caused by additives is not known.
When the fuel for the heater
is drawn from the vehicle’s fuel tank, the vehicle manufac-
turer’s specifications concerning additives are to be ob-
served.
When to changing to cold-resistant fuels, the heater must
be operated for approx. 15 minutes to ensure that the fuel
pump is filled with the new fuel.
Any addition of waste oil is not permitted.
