In the vicinity of the coolant heater, a temperature of
85 °C (185 °F) must not be exceeded under any
circumstances (e.g. during body paint work). A violation of
this temperature limit may cause permanent damage to the
electronics.
When checking the coolant level, proceed in accordance
with the vehicle manufacturer’s instructions.
The coolant in the heating circuit of the heater must
contain a minimum of 10% of a quality brand glycol based
anti-freeze.
Extracting combustion air from the vehicle interior is not
permissible under any circumstance.
The exhaust pipe outlet is to be positioned below the
vehicle floor, to the nearest possible location of the
vehicle’s left or right side.
Exhaust pipes must be routed so that exhaust fumes will
not penetrate into the vehicle’s interior. Condensation
accumulation in the exhaust pipe must be directly drained.
A condensation drain hole may be provided as required.
Do not route exhaust pipes and components within
100mm (4 inches) of flammable materials such as
polyurethane or similar foam insulation, styrene sheet
insulation, fuel tanks and containers, glycol reservoirs,
coolant lines, wood and paper products, carpet, tires,
electrical wiring, brake and air lines or any materials
deemed to be flammable or heat sensitive.
Do not terminate exhaust above flammable materials such
as polyurethane or similar foam, insulation, styrene sheet
insulation, fuel tanks and containers, glycol reservoirs,
coolant lines, wood and paper products, carpet, tires,
electrical wiring, brake and air lines or any materials
deemed to be flammable or heat sensitive.
Electrical lines, switch gear, and control gear of the heater
must be located in the vehicle so that their proper function
cannot be impaired under normal operating conditions.
The function of any parts vital for vehicle operation must
not be impaired.
The operational state of the heater, i.e. an indication
“on” or “off”, must be clearly visible to the operator.
The coolant heater may only be operated within the
specified operating voltage range designated by type.
The coolant heater may only be operated with the specified
fuel as recommended by the vehicle manufacturer.
For the routing of fuel lines, the following important
regulations must be adhered to:
•
Fuel lines are to be installed in such a way that they
remain unaffected by torsional stresses created by
vehicle and engine movement. They must be
protected against mechanical damage. Fuel lines
must be securely fastened to the vehicle every 12
inches (30 cm.) or less along the total length from
heater to fuel tank. Fuel-carrying parts are to be
protected against excessive heat and are to be
installed so that any dripping or evaporating fuel can
neither accumulate nor be ignited by hot components
or electrical equipment.
•
In buses, fuel lines are not to be located in the
passenger area or in the driver’s compartment.
Fuel supply must not be by means of gravity or
pressurization of the fuel tank.
•
The fuel tank must either be equipped with a vent
cap or be ventilated in another way (ventilation line).
•
The operational state of the heater, i.e. an indication
“on” or “off”, must be clearly visible to the operator.
