Safety instructions for installation and
operation
Caution!
Safety instructions for installation and operation!
• Repairs by unauthorised third parties and / or not
using original spare parts are dangerous and
therefore not allowed. They result in expiry of the
type permit of the heater; consequently, when

the vehicle operating licence.
• The following measures are not allowed:
– Changes to components relevant to the heater.
– Use of third-party components not approved by
Eberspächer.
– Nonconformities in installation or operation from
the statutory regulations, safety instructions or
specifications relevant to safe operation as stated
in the installation instructions and operating
instructions. This applies in particular to the
electrical wiring, fuel supply, combustion air
system and exhaust system.
• Only original accessories and original spare parts
must be used during installation or repairs.
• When carrying out electric welding on the vehicle,
the plus pole cable at the battery should be
disconnected and placed at ground to protect the
controller.
• The heater must not be operated where there is a
risk of an accumulation of flammable vapours or
dust, for example close to
– fuel depot
– coal depot
– wood depot
– grain depots etc.
• The heater must be switched off when refuelling.
• When the heater is mounted in a safety housing
etc., the installation compartment of the heater is
not a stowage compartment and must be kept
clear. In particular fuel canisters, oil cans, spray
cans, gas cartridges, fire extinguishers, cleaning
rags, items of clothing, paper etc. must not be
stored or transported on or next to the heater.
• Defect fuses must only be replaced by fuses with the
prescribed rating.
• If fuel leaks from the heater fuel system, arrange for
the damage to be repaired immediately by a JE
service partner.
• After-running of the heater must not be interrupted
prematurely e.g. by pressing the battery
disconnecting switch, apart from in the case of an
emergency stop.

Installation3
Installation and location
The heater is suitable and certified for installation in
parts of vehicles used by persons.
Installation in the cab or passenger compartments of
coaches or buses with more than 9 seats is not
allowed.
When installing in compartments used by persons, the
exhaust, combustion air and fuel pipes in these areas
must not have any detachable connections and must
be routed splash-waterproof in the breakthroughs.
For this reason, the heater can be mounted with its
foot using the flange seal in the foot to the vehicle
floor or to an outer wall of the vehicle.
The electronic control is integrated in the heater
which makes wiring during installation much easier.
Please note!
• When installing the heater, always make sure there
is sufficient clearance left for intake of the heater air
and for dismantling the glow plug and controller.
• Observe the regulations and safety instructions for
this chapter, given on page 4 – 7.
