Heating characteristics
When the heater is switched on, the heat flows throughthe vehicle heat exchanger and the vehicle engine.Once the cooling water has reached a temperature ofapprox. 30 °C, depending on the selected fan settingthe vehicle fan is switched on and the heat is alsoconveyed to the passenger compartment.
Connection to the cooling water circuit
Integrate the heater in the water feed pipe fromthe vehicle engine to the heat exchanger “inlineconnection”
Disconnect the water feed pipe from the vehicle engineto the vehicle heat exchanger. Connect up the heaterwith connection pieces and water hoses to the waterfeed pipe.
Integrate the heater in the cooling water circuitwith a non-return valve
Disconnect the water feed pipe from the vehicleengine to the vehicle heat exchanger and insert thenon-return valve. Connect up the heater to the non-return valve using the water hoses.
Heating characteristics
When the heater is switched on, the heat flows throughthe vehicle heat exchanger only to the vehicle engine.Once the cooling water has reached a temperature ofapprox. 30 °C, depending on the selected fan settingthe vehicle fan is switched on and the heat is alsoconveyed to the passenger compartment.
Advantage compared to “inline connection”cooling water circuitNo loss of efficiency in the vehicle heating when theheater is switched off.
Small coolant circuitFast heating of the passenger compartment. Initiallythe heat produced by the heater is only conveyed tothe heat exchanger up to a cooling water temperatureof approx. 70 °C. This heats the passengercompartment up quickly.Large cooling water circuitIf the cooling water temperature continues to increase,the thermostat slowly changes over to the large circuit(full change-over at approx. 75 °C). This heats thepassenger compartment up and also allows for enginepre-heating.
Connection to the cooling water circuit
Integrate the heater in the cooling water circuitwith a non-return valve, thermostat and T-piece(for HYDRONIC B 5 W SC / D 5 W SC only)
Disconnect the water feed pipe from the vehicleengine to the vehicle heat exchanger and insertthe non-return valve.Disconnect the water return pipe from the heatexchanger to the vehicle engine and insert theT-piece.Connect the heater and thermostat with water hosesto the non-return vale and T-piece as shown in thediagram.
Cooling water temperature < 70 °C –small coolant circuit:Connection no. 1 – open to the heaterConnection no. 2 – open to the T-pieceConnection no. 3 – closed to the non-return valve

Heating characteristics
Pre-heating mode – small coolant circuitFor the pre-heating mode, the heat is conveyed onlyto the vehicle heat exchanger so that the passengercompartment heats up quickly.
Extra heating function – partial circuitWhen the vehicle engine starts up – low speed – partof the heat is conveyed to the vehicle engine.Shortens the warming up phase for the engine andheats the passenger compartment.
Extra heating function – large coolant circuitAt higher engine speeds (approx. 200 rpm), the heatis distributed evenly between the heat exchanger andthe vehicle engine. Shortens the warming up phaseeven further and heats the passenger compartment.
Connection to the coolant circuit
Integrate heater in coolant circuit with thecombination valve
Combination valve with 5 connections
If the water feed pipe and water return pipe from thevehicle engine to the heat exchanger are installedseparately, the combination valve with 5 connectionsand an additional T-piece has to be used.

Fuel supply
Fuel quality for petrol heatersThe heater can run on commercially available fuelas per DIN EN 228, as used in the vehicle tank.
Fuel quality for diesel heatersThe heater can run on commercially available dieselfuel as per DIN EN 590 as used in the vehicle tank.
Fuel for special casesIn special cases (above 0 °C), the heater can also runon fuel oil EL or paraffin.
Fuel for low temperaturesRefineries and fuel service stations automaticallyadjust the fuel to normal winter temperatures (winterdiesel). This means that difficulties are only to beexpected for extreme drops in temperature, as alsoapply to the vehicle engine. Please also refer to thevehicle manual.
If the heater is run from a separate tank, pleasecomply with the following rules:For temperatures above 0 °C, any kind of diesel fuelas per DIN EN 590 can be used.
If no special diesel fuel is available for lowtemperatures, then paraffin or petrol should be mixedwith the fuel according to the following table:
Temperature Winterdiesel Addition 0 °C to –25 °C 100 % ––25 °C to –40 °C 50 %* 50 % paraffin
or petrol
* or 100 % special cold diesel fuel (Arctic diesel)
• Mixtures with used oil are not allowed!
• After refuelling with winter or cold diesel or the listedblends, the fuel pipes and the dosing pump must befilled with the new fuel by letting the heater run for15 mins.!
Operation with biodiesel (PME)The heater is not certified for operation with biodiesel.

Operating instructions
The heater is operated by a control unit.The control unit is accompanied by detailed operatinginstructions which you will receive from the companyinstalling the heater.
The control units (e.g. mini timer, module timer) aresupplied accompanied with operating instructionswhich will be handed over to you by the companyinstalling the heater).
Important instructions for operation
Safety checks before the startAfter a longer interval in operations (after the summermonths) the fuse must be put in position and / or theheater connected up to the battery. Check that allparts fit firmly (tighten screws where necessary).Check the fuel system visually for any leaks.
Before switching onBefore switching on or pre-programming the heater,adjust the heating control in the vehicle to “WARM”(maximum setting) and the fan to “SLOW” (low powerconsumption).In vehicles with automatic heating, adjust the heatingcontrol to “MAX” and open the heating vents beforeswitching the ignition off.
Pre-venting with change-over “heating / venting”Pre-venting means the possibility of starting thevehicle fan directly from the heater preselection timeror, even more convenient, from the radio remotecontrol TP4i or TP41i, thus bypassing the heatingmode, so that the passenger compartment, whichfrequently heats up considerably in summer weather,can be ventilated briefly with fresh air (separatewiring).
Heating at high altitudesWhen using the heater at high altitudes, please note:
• Heating at altitudes up to 1500 m:– Unlimited heating possible.
• Heating at altitudes over 1500 mm:– Heating is possible for short periods at this
altitude (e.g. driving over a mountain pass ortaking a break in a journey).
– In the event of a lengthy stay, e.g. wintercamping, it is necessary to adjust the fuel supplyto the altitude, please contact a JE partner forfurther information.
In diesel heaters, 12 volt, it is possible to install analtitude pump kit (Order No.: 24 0244 00 00 00),which allows the heater to be run at altitudes over1500 m and up to 2750 m, even during a lengthy stay.
Operation and function4
Initial commissioning
The following points are to be checked by thecompany installing the heater during initialcommissioning.
• After installation of the heater, the coolant circuitand the whole fuel supply system must be ventedcarefully. Comply with the instructions issued by thevehicle manufacturer.
• Open the coolant circuit before the trial run (se thetemperature control to “WARM”).
• During the trial run of the heater, check all water andfuel connections for leaks and firm fitting.
• If the heater shows a fault during operation, findand eliminate the cause of the fault using adiagnosis unit.
Description of functions
Switching on (pre-heating mode)When the heater is switched on, the control lamp inthe control unit (mini-timer, module timer) lights up.The water pump and the combustion air fan start up.After a certain programme with pre-rinsing and pre-heating, the glow plug and fuel dosing pump start thecombustion procedure. Once a stable flame hasformed, the glow plug switches off under time control.
Heating modeDepending on heating requirements, the heater isadjusted in the following stages:LARGE – SMALL – OFF (pause).The temperature limits are permanently programmed inthe electronic controller.If the heating requirements in the “SMALL” stage areso small that the cooling water temperature reaches85°C, the heater goes into the pause mode.The heater continues to run on for approx. 130seconds, then it switches off (pause mode).The control lamp lights up and the water pumpcontinues to run, even in the pause mode.
To compensate for the low heating requirementscoming from the vehicle engine, the heater can beoperated as pre-heater or combined pre-heater andextra heater, depending on the settings (wiring seecircuit diagram).

Operation and function4
Control and safety devices
• If the heater does not ignite within 90 secondsafter starting the fuel pump, the start is repeated.If the heater still does not ignite after another90 seconds, the heater is switched off. After anunacceptable number of failed start attempts, thecontroller is locked.*
• If the flame goes off by itself during operation, theheater is restarted.If the heater does not ignite within 90 secondsafter the fuel pump has started again, or it ignitesbut goes off again within 15 minutes, the heater isswitched off.This status can be remedied by briefly switchingoff and on again.
• In the case of overheating (e.g. lack of water,poorly vented coolant circuit), the overheatingsensor triggers, the fuel supply is interrupted andthe heater switched off.Once the cause of overheating has beeneliminated, the heater can be re-started byswitching off and on again (on condition that theheater has cooled down again sufficiently, coolingwater temperature < 70 °C).After the heater has been switched off foroverheating an unacceptable number of times,the controller is locked.*
• The heater is switched off if the upper or lowervoltage limit is reached.
• The heater does not start up when the glow plug isdefect or when the electric lead to the dosing pumpis interrupted.
• The speed of the fan motor is monitoredcontinuously.If the fan motor does not start up, if it is blockedor if the speed falls below 40 % of the nominalspeed, the heater is switched off after 60 sec.
* The controller can be enabled again and the faultsread off:• using the module timer• using the radio remote control TP5.For other controls:• by connecting up a diagnosis unit• using the customer service program KD 2000.For operation and fault list, please refer to theenclosed operating instructions or thetroubleshooting and repair instructions for theheater.
Do not switch the heater off and on again more thantwice.
Emergency shutdown – EMERGENCY OFFIf an emergency shutdown – EMERGENCY OFF –is necessary during operation, proceed as follows:• Switch the heater off with the control or• pull the fuse out or• disconnect the heater from the battery.
