4 Technical Data
4.1 Thermo Top E
Where no threshold values are specified technical data in
the table are understood to include standard tolerances
for heater units of ± 10 % at an ambient temperature of
+ 20° C.
All electrical components are selected for a nominal
voltage of 12 Volts.
Propellant for Thermo Top E (Fuel):
The proper fuel is the fuel specified by the vehicle
manufacturer.
Propellant for Thermo Top E (Diesel):
The proper Diesel fuel is the one specified by the vehicle
manufacturer. When switching to low temperature
propellants the heater must be operated for at least
15 minutes to prime the fuel pipe and pump with the new
type of fuel.
A persistent influence by additives is not known.
*) Operation only permitted with mixture Diesel/PME with PME quantity < 50 %.
