Technical data
Except where limit values are specified, these technical data refer to the
usual heater tolerances of
±
10% at an ambient temperature of +20°C
and at the rated voltage.
NOTE:
The assignment of circulating pumps to heaters must be made using the
water-side resistors.
14.1. Fuel
The diesel fuel specified by the manufacturer must be used. Heating oil
of class EL (not heating oil class L) can also be used as long as it of
standard German market quality.
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 fuel is extracted from a separate fuel tank, a winter diesel or equivalent
winter PME fuel must be used in temperatures below 0°C. Media to
improve the flow properties of the fuel may also be used.
If you change to low-temperature fuel, the heater must be operated for
approx. 15 minutes so that the fuel line, filter and fuel pump are filled
with the new fuel.
