±
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/flame detector are
designed either for 12-volt or 24-volt operation.
The digital timer*, temperature limiter and temperature sen-
sor are voltage-independent components.
* Presetting of heater operating times is not possible for
TRS-operation
Fuel for AT 3500/5000 B (Petrol):
The fuel specified by the vehicle manufacturer is suitable
as fuel for the heater.
Fuel for AT 3500/5000 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 conform-
s to the usual quality on the German market in accordance
