Technical Data
16. Technical Data
Except where limit values are specified, the technical data refer to the usual heater tolerances of
±
10% at an ambient
temperature of +20 °C (68 °F) and at the rated voltage and in rated conditions.
16.1 Electrical Components:
Control unit, motor, metering pump, lamp in the timer and ceramic glow pin / flame monitor are designed for either 12
V or 24 V.
The timer, overheating sensor and temperature sensor component are not dependent on voltage.
16.2 Fuel for Air Top 2000 ST B (Gasoline):
The fuel specified by the vehicle manufacturer must be used.
16.3 Fuel for Air Top 2000 ST D (Diesel/Heating Oil):
The diesel fuel specified by the vehicle manufacturer must be used. Heating oil may also be used as long as it complies
to the normal quality available on the North American market.
We know of no negative influences due to additives.
If fuel is extracted from the vehicle’s tank, follow the additive instructions issued by the vehicle manufacturer.
If you change to low-temperature fuel, the heater must be operated for approx. 15 minutes so that the fuel system is
filled with the new fuel.
The Air Top 2000 ST heater is also licensed for use with PME (bio-diesel), which complies with DIN EN 14214.
