1.The Introduction DBW 2010 / 2012 / 2020 / 2022 / 300 / 350
102
This heating device can only be mounted on motor
vehicles, of which the minimum amount of the cooling
liquid is 10 liters or on independent heating systems.
The heating device cannot be installed in the driver or
passenger cabin of the vehicles. In the case that the
heating device should be installed in such location at any
rate, the assembly box must be completely insulated in
the direction of the interior of the cabin of the vehicle. The
assembly box must have sufficient ventilation from
outside so that maximum 85
0
C will not be exceeded in
the box. Failures could be result in the case that this
temperature will be exceeded.
DANGER
The heating device should not be operated in closed
locations such as garage or workshop without the
suction system, not even as time programmed, due
to the danger of poisoning and suffocation.
The heating device must be shut off in places such
as gas stations or filling stations due to explosion
danger.
ATTENTION
The heating device should be shut off in places with
the possibility of the availability of combustible vapor
or dust such as near the fuel, coal, wood shavings,
wheat storage areas or similar places due the danger
of explosion.
The temperature of 110 0C (storage temperature) should
not be exceeded near the control device (for instance,
during painting tasks on the vehicle).Permanent damage
could be inflicted on the electronic parts if the
temperature limit is exceeded. The level of the cooling
liquid should be checked in accordance with the
instructions of the vehicle manufacturer. The water in the
heating circuit of the heating device should contain quality
anti-freeze material in a ratio of 10 % at minimum.
The admixtures in the heating circuit should not harm
metal, plastic or rubber parts and should not lead to
sedimentary formation.
The opening pressure in the vehicle cooling system –
which is normally indicated on the radiator cap – must be
between 0,4 and 2.0 bar positive working pressure (this
applies also for the separate heating circuits).
1.6 The Legal Provisions for the
Assembly
WARNING
The provisions of these directives are binding within
the validity area of the EU Directive 70/156/EEC and
should be taken into consideration in the countries,
in which particular regulations pertaining to this
issue are not available! (Citation from 2001/156/EU
Annex VII)
1.7.1. A conspicuous operation indicator within the
visual area of the operator should give information as to
whether or not the heater is working.
WARNING
Please refer to the assembly instructions for other
warnings and provisions related to the installation on the
vehicles.
The supply of the combustion air from within the vehicle
is prohibited. In the case that the mouth of the exhaust
pipe is upwards at the side or if the exhaust pipe passes
underneath the bottom of the vehicle, it should be brought
near the driver cabin or the lateral or back border lines of
the vehicle. The exhaust pipes must be laid in such way
that the exhaust gases cannot enter the interior part of
the vehicle. The parts that are important with respect to
the functioning of the vehicle should not be adversely
affected. The condensation water residues in the exhaust
pipe should be directly discharged and the permission will
be granted, if the need arises, for a hole to be drilled in
order to evacuate the condensation water.
The entrance clearance for the combustion air and the
exit clearance for the exhaust air must be manufactured
in such way that a ball of 16 mm cannot enter through
such holes.
The electrical lines and the circuit and control elements of
the heating device should be installed in such way on the
vehicle that perfect operation will not be adversely
affected under normal conditions.
The articles 45 and 46 of the German Traffic Regulation
for Land Roads must be taken into consideration for
laying the fuel lines and the installation of the additional
fuel tank. The most important articles of the Regulation
are:
• The fuel lines must be manufactured and
installed in such way that the torsion of the
vehicle, movements of the engine, etc. will not
have any adverse influence on the life time of the
lines. They must be protected against mechanical
damage. The fuel lines should be protected
against excessive heat that could spoil the work
and they should be installed in such way that the
collection of the dropping or vaporizing fuel or the
inflammation as a result of the heat or the parts
with electrical current will not be possible.
