    Fuel quality for petrol heaters

    The heater can run on commercially available fuelas per DIN EN 228, as used in the vehicle tank.

    Fuel quality for diesel heaters

    In special cases (above 0C), the heater can alsorun on 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 be

    expected 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 0C, 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 bis 25 C 100 % 25 C bis 40 C 50 %* 50 % paraffin

    or petrol

    * or 100% special cold diesel fuel (Arctic diesel)

    Please note!

    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 notcertified for operation with biodiesel.

    Operation and function4

    Operating instructions

    If the vehicle engine is not providing enough heat inthe warming-up phase, in city traffic or in trafficcongestion, the heater switches on automatically andsupports the vehicle's own heating system.

    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.

    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)

    Heating is not possible for longer periods at thisaltitude (e.g. winter camping).

    Initial commissioning

    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 open).

    During the trial run of the heater, check all water and

    fuel 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 (additional heating mode)After a certain program sequence, the heater startsthe combustion air fan, glow plug and fuel dosingpump. Once a stable flame has formed in thecombustion chamber, the glow plug switches offagain 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 reaches

    85C, 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.

    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, the heater isswitched off.The fault shutdown can be cancelled by switchingoff and on again briefly (ignition ON / OFF).

    In the case of overheating (e.g. lack of water, poorlyvented coolant circuit), the overheating sensortriggers, the fuel supply is interrupted and the heaterswitched off.Once the cause of overheating has been eliminated,the heater can be started by switching off and onagain (ignition ON / OFF), on condition that theheater has cooled down again sufficiently, coolingwater temperature

    Electrical system5

    Heater wiring

    Caution!

    Safety instructions for wiring the heater!The heater is to be connected up electricallyaccording to the EMC directives.EMC can be affected if the heater is not connected upcorrectly. For this reason, comply with the followinginstructions:

    Ensure that the insulation of electrical cables is notdamaged. Avoid: chafing, kinking, jamming orexposure to heat.

    In waterproof connectors, seal any connector

    chambers not in use with filler plugs to ensure theyare dirt-proof and water-proof.

    Electrical connections and ground connections mustbe free of corrosion and firmly connected.

    Lubricate connections and ground connectionsoutside the heater interior with contact grease.

    Comply with the following when wiring the heater and thecontrol element: Electrical leads, switchgear and controllers must be

    arranged in the vehicle so that they can functionperfectly under normal operating conditions(e.g.heat exposure, moisture etc.).

    The following cable cross sections are to be usedbetween the battery and heater. This ensures thatthe max. tolerable voltage loss in the cables doesnot exceed 0.5 V for 12 V or 1 V for 24 V ratedvoltage.

    Cable cross sections for a cable length of up to 5 m (plus cable + minus cable) = cable cross section 4 mm from 5 to 8 m (plus cable + minus cable) = cable cross section 6 mm

    If the plus cable is to be connected to the fuse box(e.g. terminal 30), the vehicle cable from the batteryto the fuse box must be included in rating the overallcable length and possibly re-dimensioned ifnecessary.

    Insulate unused cable ends.

    Guarantee conditions8

    Guarantee

    We guarantee the assured characteristics and free-dom from faults in conformity with the current state ofthe art. Changes in design which we execute infulfilment of an order are not an entitlement for com-plaint.

    The guarantee covers a period of 24 months; forretrofitting the period commences with the date whenthe heater was installed; for serial installation theperiod commences with the date of acceptance of thevehicle with the heater. This presupposes that thecompleted guarantee card is immediately returnedafter the heater has been installed.

    We are entitled to choose within the guarantee

    whether an objected product is to be repaired orreplaced. Replaced parts become our property andmust be forwarded to us, together with the guaranteeapplication, by way of the servicing workshop.With heaters the objected part must be immediatelybrought in the installed state to the servicing work-shop so that the fault can be remedied and a writtenguarantee claim can be submitted. If visiting theservicing workshop involves unjustifiable expenses(e.g. with building machinery), then the nearest servic-ing workshop must be informed, and the objected partmust be kept in readiness for assessment.

    Furthermore, we bear the dismantling and installingcosts for parts that are built into vehicles or station-ary equipment. However, this presupposes that thework is completed by us or a workshop authorised byus. In the event of unusual dismantling and installingconditions, e.g. due to the peculiarities of the givenvehicle, we will only bear the expenses to acommensurate extent. If the repair work is completedat the ordering party, then the ordering party mustbear the cost of travel time and travel expenses.There is no right to claim rescission or a reduction,except if we are unable to remedy the fault. Theguarantee obligation becomes null and void if thedelivered object is changed by a third party or byincorporating parts of alien origin, except if the fault isnot in a causal connection with the change. It alsobecomes null and void if mounting and operating ruleshave not been observed. Natural wear and damageresulting from improper treatment or overloading areexempted from the guarantee. Moreover, we cannotbe held liable for the changed state or manner ofoperation of our products due to improper storage aswell as climatic or other influences. The guaranteedoes not cover faults resulting from constructionalpeculiarities or the selection of unsuitable materials

    or inappropriate installation in a vehicle which theordering party has stipulated contrary to our previousinformation. The guarantee obligation is not extendedor renewed as a result of the repair or replacement.

    Liability

    In so far as there are no alternative provisions inthese conditions, claims for compensation, particularlyas a result of a positive contract violation andviolation of mutual confidence in the preparation ofa contract, are excluded to the legally permissibleextent. If action based on law that is not modifiable istaken against the ordering party on account of faultliability vis--vis a third party, then we will support theordering party to the same extent as the orderingparty would be directly liable.The principles of 254 BGB (German Civil Code) areapplicable to compensation for damage between theordering party and us. This also appliesin the event that we directly assert a claim.

    Place of jurisdiction

    The place of jurisdiction is the competent court forEsslingen or, according to our choice, the competentcourt for the domicile of the workshop that executedthe order, provided that: The customer is a merchant who has been entered

    as such in the Commercial Register; The customer does not have a general inland place

    of jurisdiction, or after the contract was concluded, the customer

    moves his domicile or customary whereabouts awayabroad, or if the customer's domicile or customarywhereabouts is unknown when a suitis filed.

    We are also entitled to file a suit with the court thatis competent for the seat or branch of the orderingparty.
