ENERAL AFETY
The year of first operation must be permanently marked
on the identification label by removing the relevant
number of the year.
The heaters are cleared for heating the vehicle engine
and the passenger cabin. The use of the heater in
vehicles not subject to the EU Directive 70/156/EEC (e.g.
ships) is partly governed by regional regulations.
The heater may only be fitted in vehicles or in
independent heating systems with a minimum coolant
capacity of 10 liters for DBW 2010 and 15 liters for DBW
2020 and 300.
The heater must not be installed in the passenger or
driver compartments of vehicles. Should the heater
nevertheless be installed in such a compartment, the
installation box must be sealed tight against the vehicle
interior.
There must be sufficient ventilation of the installation box
from the exterior in order not to exceed a maximum
temperature of 85° C (185 °F) in the installation box.
Excessive temperatures may cause malfunctions.
WARNING: Due to the danger of
poisoning and suffocation the heater must
not be operated, not even with timed
operation, in enclosed areas such as
garages or workshops not equipped with
an exhaust venting facility.
WARNING: At filling stations and fuel
depots the heater must be switched off to
prevent explosions.
CAUTION: Where flammable fumes or
dust may build up (e.g. in the vicinity of
fuel, coal, wood, cereal depots, or similar
installations) the heater must be switched
off to prevent explosions.
The heater must not be operated near
flammable materials such as dry grass and
leaves, cardboard boxes, paper, etc.
