authorised by the manufacturer according to the
instructions in this manual and possibly according to
special installation recommendations; the same
applies to any repairs to be carried out in the case of
repairs or guarantee claims.
• Repairs by non-authorised third-parties and / or with
non-original spare parts are dangerous and are
therefore not allowed. They result in expiry of the
type-approval of the heater; consequently, when
installed in motor vehicles they can cause expiry of
the vehicle’s operating licence.
• The following measures are not allowed:
– Changes to components relevant to the heater.
– Use of third-party components not approved by J.
Eberspächer GmbH & Co. KG.
– Installation or operation not conforming to the
statutory regulations, safety instructions or
specifications relevant for 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.
• Original accessories and original spare parts only may
be used for installation or repairs.
• Only the control units approved by Eberspächer may
be used to operate the heater. Use of other control
units can cause malfunctions.
• Before the heater is installed again in another
vehicle, rinse the heater parts carrying water with
clear water.
• When carrying out electric welding on the vehicle,
the positive cable at the battery should be disconnected and placed at ground to protect the control
box.
• The heater must not be operated where there is a
risk of an accumulation of flammable vapours or dust,
e.g. close to
– Fuel depot
– Coal depot
– Wood depot
– Grain depot, etc.
• The heater must be switched off when refuelling.
• If the heater is installed in a safety casing or similar,
its installation box must not be used as storage space
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.
• Defective fuses may be replaced by fuses with the
prescribed rating only.
• If fuel leaks from the heater fuel system, arrange for
the damage to be repaired immediately by a JE
service partner.
• When topping up the coolant, only use the coolant
permitted by the vehicle manufacturer, see the
vehicle operating manual. Any blending with
unapproved coolant can cause damage to the engine
and heater.
• The after-running of the heater must not be
prematurely interrupted e.g. by pressing the battery
isolating switch, except for an emergency stop.

Connection to the cooling water circuit
The heater is integrated in the cooling water circuit, in
the water flow hose from the vehicle engine to the heat
exchanger; for which there are four installation options.
The installation options are described on pages 19 –
21.
Danger!
Risk of injuries and burns!
It is possible for the coolant and components of the
coolant circuit to get very hot.
• Parts conveying water must be routed and fastened
in such a way that they pose no temperature risk to
man, animals or material sensitive to temperature
from radiation / direct contact.
• Before working on the coolant circuit, switch the
heater off and wait until all components have cooled
down completely, if necessary wear safety gloves.
Please note!
• When installing the heater, please note the direction
of flow of the cooling water circuit.
• Fill the heater and water hoses with coolant before
connecting them to the cooling water circuit; to do
this, open the vent screw on the heater.
• Route the water hoses without any kinks, and in a
rising position if possible.
• When routing the water pipes, maintain sufficient
clearance from hot vehicle parts.
• Protect all water hoses / water pipes from chafing
and from extreme temperatures.
• Secure all hose connections with hose clips
(tightening torque = 1.5 Nm).
• Re-tighten the hose clips after the vehicle has been
running for 2 hours or has travelled 100 km.
• The minimum water flow rate is only guaranteed if the
temperature difference of the heating medium does
not exceed 10 K between water inlet and water
outlet during heating.
• Only overpressure valves with an opening pressure of
min. 0.4 – max. 2 bar may be used in the coolant
circuit.
• The coolant liquid must contain at least 10 %
antifreeze all year round as corrosion protection.
• The cooling liquid must contain sufficient antifreeze
for low temperatures.
• Before commissioning the heater or after changing
the cooling liquid, the whole coolant circuit including
heater must be vented free of bubbles according to
the instructions issued by the vehicle manufacturer.
• Top up using only coolant approved by the vehicle
manufacturer.

Connection to the cooling water circuit
Integrate heater in the water flow hose from the
vehicle engine to the heat exchanger, “inline
connection”
Cut the water flow hose from the vehicle engine to the
vehicle’s heat exchanger. Use connectors and water
hoses to connect the heater to the water flow hose.
Integrate the heater and non-return valve in the
cooling water circuit
Cut the water flow hose from the vehicle engine to the
vehicle’s heat exchanger and insert the non-return
valve. Use water hoses to connect the heater to the
non-return valve.
Heating characteristics
If the heater is switched on, the heat is fed to the
vehicle’s own heat exchanger and to the vehicle’s
engine. After the cooling water has reached a temperature of approx. 30 °C – depends on the selected
blower setting – the vehicle blower switches on and
the heat is then also fed to the passenger
compartment.

vehicle interior
Initially, up to a cooling water temperature of approx.
67 °C, the heater’s heat is fed to the heat exchanger
only – fast heating of the inside of the vehicle.
Small cooling water circuit with heat discharge to the
vehicle engine
From a cooling water temperature of approx 67 °C,
part of the heater’s heat is also passed to the vehicle’s
engine. This causes slow heating of the engine circuit,
without rapid cooling of the “small cooling water circuit” for interior heating.
Heating characteristics in auxiliary heater mode
Large cooling water circuit
While the vehicle’s engine is running the heat is uniformly distributed between the heat exchanger and the
vehicle engine – further shortening of the heating up
phase and heating of the inside of the vehicle.
Install combination valve with 6 connections
Cut the water flow hose and the water return hose
from the vehicle engine to the vehicle’s heat exchanger
and insert the combination valve. Use water hoses to
connect the heater to the combination valve – as
shown in the sketch.

Exhaust system
(For exhaust system diagram see page 23)
Mounting the exhaust system
The universal installation kit includes a flexible exhaust
pipe, inner Ø 24 mm, 1000 mm long and an exhaust
silencer.
The flexible exhaust pipe can be shortened to 20 cm or
lengthened to max. 2 m, depending on the installation
conditions.
Fasten the exhaust silencer to a suitable position in the
vehicle.
Lay the flexible exhaust pipe from the heater to the
exhaust silencer and fasten with pipe clips.
Fix a short exhaust pipe end (with end sleeve) to the
exhaust silencer with a pipe clip.
Caution!
Safety instructions!
The whole exhaust system gets very hot while the
heater is running and immediately afterwards.
This is why the exhaust system must be routed according to these installation instructions.
• The exhaust outlet must end in the open air.
• The exhaust pipe may not protrude beyond the lateral
limits of the vehicle.
• Install the exhaust pipe sloping slightly downwards. If
necessary, make a drain hole with an approx. Ø of
5 mm at the lowest point as a condensation outlet.
• Important functional parts of the vehicle may not be
impaired (maintain sufficient clearance).
• Mount the exhaust pipe with sufficient clearance to
heat-sensitive parts. Pay particular attention to fuel
pipes (made of plastic or metal), electrical cables and
brake hoses etc.!
• Exhaust pipes must be securely fixed (recommended
clearance of 50 cm) to avoid damage due to
vibrations.
• Lay the exhaust system so that the outflowing
exhaust gases are not sucked in as combustion air.
• The mouth of the exhaust pipe must not become
clogged with dirt and snow.
• The mouth of the exhaust pipe must not point in the
direction of travel.
• Always fix the exhaust silencer to the vehicle.
Danger!
Risk of injuries and burns!
Every type of combustion produces high temperatures
and toxic exhaust fumes.
This is why the exhaust system must be routed according to these installation instructions.
• Do not perform any work on the exhaust system while
the heater is working.
• Before working on the exhaust system, switch off the
heater first and wait until all the parts have
completely cooled down, wear safety gloves if
necessary.
• Do not inhale exhaust fumes.
Please note!
• Comply with the regulations and safety instructions for
this chapter given on page 4 – 7.
• The exhaust pipe end should be much shorter than
the flexible exhaust pipe from the heater to the
exhaust silencer.

Combustion air system
Installing the combustion air system
The heater – as described in these installation instructions – is installed in the engine compartment. It is not
necessary to install a combustion air hose if the intake
connection for the combustion air is in an area in
which the combustion air does not get hotter than
25 °C and in which neither spray water or dust / dirt
are to be expected. Otherwise, a flexible combustion
air hose, inner Ø 20 mm up to 1.5 m long must be
installed in order to take the combustion air from an
area which fulfils the conditions named above.
Please note!
Comply with the regulations and safety instructions for
this chapter given on page 4 – 7.
Caution!
Safety instructions for the combustion air system!
• The combustion air opening must be free at all times.
• Lay the combustion air intake to ensure that exhaust
fumes cannot be sucked in as combustion air.
• Arrange the combustion air intake so that it is not
directed against the wind blast or airstream.
• Do not allow the combustion air intake to become
clogged with dirt and snow.
• Install the combustion air intake system sloping
slightly downwards. If necessary, make a drain hole
approx. Ø 5 mm at the lowest point to drain off
condensation.

Fuel supply
Fuel quality for diesel heaters
The heater runs problem-free on standard commercial
quality fuel in accordance with DIN EN 590, which you
use to run your vehicle engine.
Fuel for special cases
In special cases the heater can also be run on heating
oil (above 0 °C) or kerosene / paraffin oil.
Fuel for low temperatures
Refineries and fuel service stations automatically adjust
the fuel to normal winter temperatures (winter diesel).
This means that difficulties can only arise if there is an
extreme drop in temperature, as is the case for the
vehicle engine too. Please also refer to the vehicle
manual.
If the heater is run from a separate tank, please comply
with the following rules: For temperatures above 0 °C,
any kind of diesel fuel as per DIN EN 590 can be used.
If no special diesel fuel is available for low temperatures, then paraffin or petrol should be mixed with the
fuel according to the following table:
Temperature Winter diesel Additive
0 °C to –25 °C 100 % –
–25 °C to –40 °C 50 %* 50 % kerosene
or petrol
* or 100 % special cold diesel fuel (Arctic diesel)
Please note!
• Additions of used oil are not allowed!
• After refuelling with winter or cold diesel or the listed
blends, the fuel lines and the metering pump must be
filled with the new fuel by letting the heater run for 15
minutes!
Operation with biodiesel
(FAME for diesel engines according to DIN EN 14 214)
Hydronic D 5 W SC – 24 volt
The heater is approved for operation with biodiesel up
to a temperature of –8° C (the flowability reduces at
temperatures below 0 °C).
Please note!
• When using 100 % biodiesel, the heater should be
operated twice a year with diesel fuel (in the middle
and at the end of a heating period) to burn off any
possibly accumulated biodiesel residues.
To do so, let the vehicle tank run almost empty and
fill with diesel fuel without adding any biodiesel. While
running on this tank filling, switch the heater on 2 to
3 times for 30 minutes at a time at the highest
temperature setting.
• When operating with diesel / biodiesel mixtures of up
to 50 % biodiesel, intermediate operation with pure
diesel fuel is not necessary.
Hydronic D 4 W SC – 12 volt and
Hydronic D 5 W SC – 12 volt
are not approved for running on biodiesel. The addition
of up to 10 % biodiesel is allowed.

Operating instructions
The heater is operated by a control unit. Detailed
operating instructions are supplied with the control
unit.
Please note!
You will be issued the operating instructions by the
installation workshop.
Important instructions for operation
Safety checks before starting up the heater
After a lengthy stoppage (summer months), check all
components for secure fit (tighten screws where
necessary).
Carry out a visual check of the fuel system for leaks.
Before switching on
Before switching on or pre-programming heating mode,
switch the vehicle’s heating lever to “WARM” (maximum
setting) and the blower to “slow level” (low electricity
consumption). In vehicles with automatic heating,
before switching off the ignition, switch the heating
lever to “MAX” and the required damper position to
“OPEN”.
Parking / cab ventilation with “heat / ventilate”
changeover switch
Parking / cab ventilation means: possible activation of
the vehicle blower directly via the heater’s preselection
timer or – even more useful – via the EasyStart R/R
radio remote control by bypassing heating mode, in
order to ventilate the often over-heated vehicle interior
with fresh air just before driving away (separate wiring).
Heating at high altitudes
When using the heater at high altitudes, please note:
• Heating at altitudes up to 1500 m:
• Unlimited heating possible.
• Heating at altitudes over 1500 m:
• You can use the heater at this altitude for short
periods (e.g. driving through a mountain pass or
taking a break in your journey).
– for longer stays, e.g. winter camping, it is
necessary to adjust the fuel supply to the altitude,
please contact a JE partner for further details and
advice.
Please note!
The installation of an altitude kit (Order No. 22 1000
33 22 00) enables diesel heaters to be operated at
altitudes over 1500 m, even for lengthy stays.
Initial commissioning of the heater
The following points are to be checked by the company
installing the heater during initial commissioning.
• After installation of the heater, the coolant circuit and
the whole fuel supply system must be vented carefully.
Comply with the instructions issued by the vehicle
manufacturer.
• Open the coolant circuit before the trial run (set the
temperature control to “WARM”).
• During the heater trial run, all water and fuel
connections must be checked for leaks and secure,
tight fit.
• If faults occur while the heater is running, use a
diagnostic unit to determine and correct the cause of
the fault.
Functional description
Switching on (parking heater mode)
When the heater is switched on, the operating display
in the control unit lights up. The water pump starts up.
After a defined program run, the combustion air fan,
glow plug and metering pump start and start up the
combustion. Once a stable flame has formed, the glow
plug switches off under time control.
Heating mode
Depending on the heat requirements, the heater runs
at the following levels:
HIGH – LOW – OFF (pause mode).
The temperature thresholds are permanently programmed in the electronic control box. If the heating
requirement in the “LOW” stage is so small that the
cooling water temperature reaches 85 °C, the heater
controls in pause mode. An after-run of approx. 120
seconds follows, the heater then switches off (pause
mode). The control lamp lights up and the water pump
continues running, even in pause mode.
Please note!
Depending on the connection, the heater can be operated as a parking heater or as a combined parking and
auxiliary heater to compensate for insufficient heat
output from the vehicle engine (for details of wiring, see
circuit diagram).

Control and safety devices
• If the heater does not ignite within 90 seconds after
the fuel starts to pump, the start is repeated. If the
heater still does not ignite after another 90 seconds
of fuel being pumped, the heater is automatically shut
down. After an impermissible number of failed start
attempts, the controller is locked.*
• If the flame goes off by itself during operation, the
heater is restarted. If the heater still does not ignite
within 90 seconds after the fuel pump has been
restarted, or ignites and but goes off again within 15
minutes, a safety lock-out occurs. The shutdown on
faults can be cancelled by briefly switching off and on
again.
• In the event of overheating (e.g. water shortage,
poorly ventilated cooling water circuit), the
overheating sensor triggers, the fuel feed is
interrupted and the heater is automatically shut
down. Once the cause of the overheating has been
eliminated, the heater can be re-started by switching
it off and on again (provided that the heater has
sufficiently cooled, cooling water temperature
< 70 ° C). After the heater has been shut down due
to overheating an unacceptable number of times, the
control box is locked*.
• If the lower or upper voltage limit is reached, the
heater is automatically shut down.
• The heater does not start up if the glow plug is
defective or if the electric cable to the metering pump
is interrupted.
• The speed of the blower motor is continuously
monitored. If the blower motor does not start up, if it
is blocked or if the speed falls below 40 % of the
desired speed, the heater is automatically shut down
after 60 sec.
Please note!
Do not repeat the switching off / on routine more than
twice.
Emergency shutdown – EMERGENCY OFF
If an emergency shutdown – EMERGENCY OFF – is
necessary during operation, proceed as follows:
• Switch the heater off at the control unit or
• Remove the fuse or
• Disconnect the heater from the battery.
* Cancellation of the lock or reading out errors is
possible:
• with the module timer / EasyStart T timer
• with the radio remote control TP5 / EasyStart R+.
For other control units by connecting:
• the diagnostic unit
• the customer service program KD2000 / EDiTH.
For operation and fault list, please refer to the
enclosed operating instructions or the troubleshooting
and repair instructions for the heater.

Heater wiring
Caution!
Safety instructions!
The heater is to be connected up electrically according
to the EMC directives. EMC can be affected if the heater is not connected up correctly. For this reason, comply with the following instructions:
• Ensure that the insulation of electrical cables is not
damages. Avoid: chafing, kinking, jamming or
exposure to heat.
• Seal any connector chambers of watertight
connectors not in use with filler plugs to ensure they
are dirt-proof and water-proof.
• Electrical connections and ground connections must
be free of corrosion and firmly connected.
• Lubricate connections and ground connections
outside the heater interior with contact grease.
Please note!
Comply with the following when wiring the heater and
the control unit:
• Electrical leads, switch and control gear must be
positioned in the vehicle so that they can function
perfectly under normal operating conditions without
impairment (e.g. due to heat exposure, moisture,
etc.).
• The following cable cross sections are to be used
between the battery and heater. This ensures that
the max. permissible voltage drop in the cables does
not exceed 0.5 V for 12 V or 1 V for 24 V rated
voltage.
Cable cross-sections for a cable length (plus cable +
minus cable) of:
– up to 5 m = cable cross-section 4 mm
– from 5 m to 8 m = cable cross-section 6 mm
• If the positive cable is to be connected to the fuse
box (e.g. terminal 30), the vehicle’s cable from the
battery to the fuse box must also be included in the
calculation for the total cable length and redimensioned if necessary.
• Insulate unused cable ends.

Troubleshooting / maintenance / service

If any faults occur, please check the
following items
• If the heater does not start after being switched on:
– Switch the heater off and on again.
• If the heater still does not start, check whether:
– Fuel in the tank?
– The fuses are ok?
– The electrical cables, connections, terminals, are
ok?
– The hot air, combustion air or exhaust systems are
blocked?
Troubleshooting
If, after checking these items, the heater is still faulty or
another malfunction occurs in your heater, please
contact:
• If factory-installed, your contract workshop / garage.
• If subsequently installed, the workshop / garage
which installed the heater.
Please note!
Please note that guarantee claims can expire if the
heater is modified by a third party or if non-original
parts are installed.
Maintenance instructions
• Switch the heater on once a month for about 10
minutes, even outside the heating period.
• Before the heating period starts, the heater should
undergo a trial run. If thick, persistent smoke
develops, unusual burning noises or a clear fuel smell
occurs or if electric / electronic parts overheat, the
heater must be switched off and put out of service by
removing the fuse. In this case, the heater should not
be started up again until it has been checked by
qualified staff who have been trained on Eberspächer
heaters.
• Check the openings of the combustion air supply and
exhaust system after longer standstill periods, clean if
necessary!
