Trumatic E 2800, E 2800 A E 4000, E 4000 A L.P.G. Heater with electronic control, built-in air distribution and thermostat lamp must be illuminated (the fan is running). If the indicator lamp is not illuminated, pos- sibly check the (main) switch. For this purpose observe re- spective instructions of the vehicle manufacturer. During the heating operation, while the flame is burning, the green indicator lamp lights up with twice the in- tensity. This also makes it possible to determine the in- stantaneous switching point of the room temperature. Fuses Fig. H4: The appliance fuse (F1) is located on the elec- tronic control PCB. Important note: The fine- wire fuse may only be re- placed by a fuse of identical design: 3.15 AT (slow-acting) EN 60127-2-3. Red indicator lamp „Failure“ Should a failure occur, the red indicator is illuminated per- manently. Possible causes for the failure can be e.g. no gas, insufficient combustion air, heavily soiled rotor, defec- tive fuse etc.. Deactivate by switching off and then switching on again. Flash operation indicates that the operating voltage is too low or too high for the appliance (charge battery, if necessary). In event of faults, in Germany, always contact the Truma Service Centre, Tel.: (089) 4617-142. For other countries please refer to the Interna- tional Service (page 57). Accessories Fig. H6:

1. In the event of the chimney

having been located in the vicinity of a window (or a hatch) which can be opened, especially directly beneath it, the window or hatch must re- main closed during operation (see warning plate).

2. The integrity and tight fit of

the exhaust gas double duct must be checked regularly, particularly at the end of long trips. Also check the mount- ing of the appliance and the cowl.

3. Following a blow-back

(misfire) always have the ex- haust gas system checked by an expert!

4. If appliances are assembled

on the outside of the vehicle, regularly check the flexible air ducts for damage. A damaged duct could lead to exhaust gas entering the vehicle.

5. Always keep the cowl for

conducting exhaust gas and supplying combustion air, free from contamination (slush, leaves etc.).

84. In other countries: The

technical and administrative regulations applicable in the particular country for the ap- proval and tightness test of liquid gas systems are to be respected. For your own safe- ty, it is essential that the en- tire gas installation, the de- vice itself and the exhaust gas duct, must be inspected regularly by an authorised specialist (at the most every two years). For further details on the rules and regulations in the respective country of desig- nation, please contact our agencies abroad (refer to the International Service, page 57).

5. Do not operate the ap-

pliance when refuelling the vehicle and when in the garage.

6. During the initial operation

of a brand new appliance (or after it has not been used for some time), a slight amount of fumes and smell may be noticed for a short while. This can be remedied by running the heater at maximum out- put and ensuring adequate room ventilation.

7. If the burner makes an un-

usual noise or if the flame lifts off, it is likely that the regula- tor is faulty and it is essential to have it checked.

8. Items sensitive to heat (e.g.

spray cans) must not be stored in the installation area, since excess temperatures may under certain circum- stances be incurred there. For the gas system, only gas pressure regulators with an over-pressure security device may be used. These are, for example, gas pressure regula- tors for leisure vehicles in ac- cordance with DIN 4811 or VP 306 with safety valves, and for commercial vehicles in accordance with BGV D 34, Art. 11, Para. 4 with protection against impermis- sibly high pressure increases. We recommend the Truma vehicle regulator, or, for the two-cylinder gas system in cylinder boxes which are only accessible from the outside, the Truma-Triomatic with au- tomatic reserve switchover. The Truma regulators have been specially designed for heavy duty use in caravans, boats and vehicles. In addi- tion to a safety valve they al- so have a pressure gauge with which you can check that the installation is gas- tight. Always connect the pressure regulators to the gas cylin- ders by hand, taking great care! For temperatures around 0°C and below, the regulators should be operated with a defroster system (Eis- Ex). Inspect regulator connec- tion hoses regularly for signs of weakness. For winter oper- ation only use special frost-re- sistant hoses. Gas cylinders must always be upright! If the pressure regulator is ex- posed to weather conditions - especially on trucks - always make sure to protect the reg- ulator using the Truma pro- tective cover (standard acces- sory in truck attachment kit).

The following CE Product Ident. Number is available for EU countries: E 2800 (A): CE-0085AP0231 E 4000 (A): CE-0085AP0232 General design approval of the federal office for motor vehicles: E 2800 (A): S 140 E 4000 (A): S 139

6. The installed temperature

limiter shuts off the gas sup- ply if the appliance becomes too hot. Therefore do not shut the warm air outlets and the opening for the returning cir- culating air.

7. If the electronic control

p.c.b. is defective, return it well packed. If you fail to do so, guarantee claims shall no longer be valid. Only use original p.c.b. as a spare part!

8. In Germany, according to

Section 22a of StVZO, the

heat exchanger of heaters built into motor vehicles must be replaced with an original part by the manufacturer or authorised workshops, ten years after the year of first registration (this date must be scribed on the name plate). The heater is then to be fitted with a plate indicating the selling date of the heat ex- changer and the word „origi- nal spare part“ (if exhaust ducts are conducted through rooms frequented by people, these must also be replaced by original spare parts after 10 years). The vehicle own- er is the person responsi- ble for arranging the in- spection and the replacing of the parts.

9. For conducting the exhaust

gas under the floor, the vehi- cle floor must be sealed tight. There must also be three open sides beneath the vehi- cle floor to ensure unhindered escape of the exhaust gas (snow, aprons etc.).

10. Always mount the cover

cap for the wall cowl when the appliance is not being used. This applies in particu- lar when washing the vehicle and for boats. Instructions for mobile heating appliances Truma mobile cargo-hold heating units have been ap- proved by the professional associations. They are com- plete heating appliances which are simply placed in the cargo hold with the cargo as the need arises. The heaters are completely inde- pendent and require no exter- nal connections of any kind. Approval covers only original mobile cargo-hold heaters manufactured by Truma. Re- productions by third parties have not been approved! Tru- ma refuses to give any guar- antee of safety and correct functioning in respect of a re- production mobile cargo-hold heater. The use of the appliance in vehicles used for the trans- port of hazardous goods is not permitted. General safety notes If the gas system is leak- ing or if there is a smell of gas: - extinguish all naked flames! - do not smoke! - switch off the appliances! - shut off the gas cylinder! - open the windows! - do not actuate any electrical switches! - have the entire system checked by an expert! Repairs may only be carried out by an expert! Attention: A new O-ring must always be installed after dismantling the exhaust duct!

1. Any alteration to the appli-

ance (including exhaust duct and cowl) or the use of spare parts and accessories which are important to the function of the heater and which are not original Truma parts, as well as the non-observance of the installation and operating instructions, will lead to the cancelling of the guarantee and exclusion of liability claims. It also becomes illegal to use the appliance, and in some countries this even makes it illegal to use the ve- hicle.

2. The operating pressure

for the gas supply is 30 mbar (or 28 mbar bu- tane/37 mbar propane) or 50 mbar and must corre- spond to the operating pressure of the appliance (see name plate).

3. For Germany only:

Liquid gas systems for leisure vehicles must accord with the DVGW datasheet G 607 or G 608 for water sports vehicles. For vehicles for commercial use, the relevant accident prevention regulations issued by the professional associa- tions are to be respected (BGV D 34). The inspection of the gas system is to be repeated every two years by am ap- proved liquid gas specialist (DVFG, TÜV, DEKRA). This is to be confirmed on the corre- sponding inspection certifi- cate (G 607, G 608, or BGG 935). The keeper of the ve- hicle is responsible for ar- ranging the inspection. 9Installation instructions

Please fold out page with diagrams! The installation and repair of the appliance is only to be carried out by an expert. Read the installation instruc- tions carefully prior to starting work and observe the instruc- tions! Intended use This appliance has been de- signed for installation in vehi- cles (mobile homes, caravans, boats, trucks). Other applica- tions are also possible follow- ing consultation with Truma. Approval Declaration of conformity: The Trumatic E heater has been tested and approved by the DVGW and complies with the EC guideline for gas appli- ances (90/396/EEC) as well as the associated EC guidelines. The following CE Product Ident. No. is avai-lable for EU countries: E 2800 (A): CE-0085AP0231 E 4000 (A): CE-0085AP0232 The heater is approved for in- stallation in rooms frequented by people (in motor vehicles) and for operation while the vehicle is moving. The appliance is not approved for installation inside busses. In Germany, for inspection or testing of the vehicle accord- ing to Sections 19, 20 and 21 of StVZO, the installation is also to be inspected. For subsequent installation pro- ceed as specified in Section 19 of StVZO. General Design Approval of the German Federal Of- fice for Motor Vehicles: E 2800 (A): S 140 E 4000 (A): S 139 Regulations Any alteration to the appliance (including exhaust duct and cowl) or the use of spare parts and accessories which are important for the functioning of the heater and which are not original Truma parts, as well as the non-observance of the installation and operating instructions, shall lead to the cancelling of the guarantee and exclusion of liability claims. It also becomes illegal to use the appliance, and in some countries this even makes it illegal to use the vehicle. The operating pressure for the gas supply is 30 mbar (or 28 mbar butane/37 mbar propane) or 50 mbar and must correspond to the oper- ating pressure of the appli- ance (see name plate). Take the nameplate from the operating instructions and installation instruc- tions and adhere to the ap- pliance at a place where it is clearly visible and pro- tected against damage. The year of initial opera- tion must be marked on the nameplate. When installing the appli- ance always observe the technical and administra- tive rules and regulations of the country in which the vehicle is to be regis- tered for the first time. In Germany, for example, gas appliances, cylinder mounts, the laying of lines, and accep- tance and tightness tests, must all accord with the DVGW datasheet G 607 for liquid gas systems in leisure vehicles, and G 608 for liquid gas systems in water sports vehicles respectively. For vehicles used for com- mercial purposes, the rele- vant accident prevention reg- ulations issued by the profes- sional associations are to be respected (BGV D 34). For further details on the rules and regulations in the respective country of desig- nation, please contact our agencies abroad (refer to the International Service). Exhaust gas lines and chim- neys must be laid in such a way that exhaust gases can- not penetrate into the interior of the vehicle. Operationally important parts of the vehicle must not be impaired in their function. The outlet of the ex- haust gas tube is to be posi- tioned upwards, to the side, or, in the event of the exhaust gas being laid beneath the vehicle floor, to a point in the vicinity of the side or rear de- limitation of the vehicle cab or of the vehicle itself. Hot air distribution: Hot air suction apertures must be arranged in such a way that no exhaust gases from the engine or the heating device can be drawn in. It must be ensured by means of con- struction design that the heating air introduced into the vehicle is not polluted (e.g. by oil vapour). This is achieved, for example, with air heaters with circulating air operation, both for interior in- stallations and for external in- stallations. (In heaters with fresh air operation the fresh air is not to come from the engine compartment or from the vicinity of the exhaust or the exhaust outlet of the heater). Notes on the installation in commercial vehicles The officially tested (TÜV) cylinder bracket (Art. no. 39741-00) - refer to Fig. J1 - is part of the General Design Approval of the German Fed- eral Office for Motor Vehicles, for the Trumatic E heaters, in compliance with Section 22a. of StVZO (Road Traffic Act). Here it is stated that 2 gas cylinders with a contents of max. 15 kg can be connected and used for operating the heaters while the vehicle is moving. For the protection of the cylinder valve and the gas pressure regulator, just the protective cover provided with the cylinder bracket is required. For protection against theft or for reasons of appearance, the gas cylinder can also be concealed using the lockable cylinder cabinet (Art. no. 39010-21100) - refer to Fig. J2. The cabinet is bolted with the cylinder bracket to the ve- hicle frame. When installing the heater in special vehicles (e.g. vehicles for transporting hazardous goods), the respective regula- tions for such vehicles must be observed. Notes on installation in driver's cab

1. For appliances with ex-

haust ducts under the vehicle floor, the exhaust cowl must extend into the area of the side or rear wall of the cab or vehicle, in order to make sure exhaust gas does not enter the inside of the vehicle.

2. Model-related assembly in-

structions can be obtained from Truma.

3. In Germany, for tank vehi-

cles carrying hazardous goods in the field of applica- tion covered by the ADR, the appliance is only approved with the Truma control unit. Installation instruc- tions for permanent heating appliances in cargo holds

1. It is preferable for heating

appliances to be installed in- side the location concerned. If there is a risk of water en- tering the heating appliance due to cleaning operations, install the heater types that are specially designed to be externally mounted (E 2800 A, E 4000 A).

2. If there is not enough room

in the cargo hold, a heating appliance with floor cowl should be installed on the front face. If underfloor heat- ing with wall cowl has been installed, a suitable means must be used to ensure that neither dirt nor dampness can enter the heater through the circuits for combustion prod- ucts or recirculating air.

3. Installation in vehicles used

for the transport of hazardous goods is not permitted. Notes on installation in boats For installation in boats, apply the installation instructions analogously. In this connection, also observe the following:

1. In Germany, the „Technical

specifications“ of the DVGW form G 608 must be observed for sports boats, and for com- mercial inland shipping the „guidelines for construction, fitting, testing and operation of liquid gas systems for do- mestic purposes on boats, within the scope of inland shipping“ (BGR 146) must be observed. According to these guidelines the liquid gas sys- tem is only to be installed by fitters recognised by the in- land shipping liability insur- ance association (Berufs- genossenschaft) and is only to be checked and tested by experts of this association. In other countries always ob- serve the respectively valid regulations.

2. It is not possible to install

heaters with floor cowl.

3. For further notes on instal-

lation, refer to the assembly instructions for the Trumatic E boat heater.

Choice of location Always install the appliance and its exhaust duct in such a way that it is always easily ac- cessible for service work and can be removed and in- stalled easily. For evenly distributed heat- ing, the installation of the ap- pliance should be as much in the centre of the vehicle as possible (or under the vehi- cle), and in such a way that the air distribution ducts can be routed with approximately the same length. The cowl must be placed in such a way that exhaust gas cannot find its way into the vehicle interior. For this rea- son, choose a location where there are no opening win- dows, skylights or ventilation openings directly above the cowl or for 30 cm on either side. If this is not possible, a warning plate must be placed on the inside of the window (or skylight) stating that it must be kept closed while the heater is operating. In this case refrigerator ventilation ducts must be tight-sealed from the interior of vehicle.

Exhaust duct Trumatic E 2800 (A) and E 4000 (A) heaters with wall or roof cowl must be installed only with Truma exhaust duct AA 3 (Art. no. 39320-00) - or Truma high-quality steel ex- haust duct AEM 3 (Art. no. 39360-00) for boats - and air intake duct ZR (Art. no. 39580-00), because the appli- ances have only been tested and approved with these ducts. Attention: New O-rings must installed each time the appli- ance has been dismantled. Permitted duct lengths

1. Inside installation with

wall cowl (see installation variant 1, page US 2): - Duct lengths up to max. 30 cm can be laid horizon- tally or with a downward slope up to 5 cm. - Duct lengths of up to max. 100 cm must be laid with an upward slope of at east 5 cm to the wall cowl.

2. Inside installation with

roof cowl (see installation variant 2, page US 2): - Duct lengths up to max. 200 cm must be routed upwards at an angle of at least 45 degrees.

3. Under floor installation

Secure the cowl grating (14), cowl section (11) and seal (10) with 4 screws (15) (Check correct installation po- sition - the word „Top” print- ed on the cowl section must be uppermost, and the drainage opening in the seal must be facing down). The upwardly projecting part seals the cap (16) and can be glued to the vehicle wall. Ap- plication of the adhesive is easier with the cap on. Double cowl duct connection to the heating appliance Fig. A1: First compress the exhaust duct (1) so that the coil windings are pressed against each other. Slide the clamp (4) over the exhaust duct (1). Slide the exhaust duct onto the connection fit- ting (2) over the O-ring. En- gage the clamp (4) and screw tight. Secure the air intake duct (5) on the connection fit- ting (6) with clamp (7).

Inside installation with roof cowl set See installation variant 2 (page US 2). Install roof cowl on a surface which is as straight as possi- ble, with wind flow from all sides. From the appliance to the cowl it must be possible to have a direct duct route ris- ing over the entire duct length (max. 2 m)! Assembling the condensate trap A condensate trap has to be installed between the heater and the double duct to allow condensation water and rain water to drain away. Attention: The exhaust gas double duct must not sag - the condensate trap must be the lowest point! Fig. A3: Fully open the clamp (4) and slide over the O-ring onto the exhaust gas connec- tion fitting (2). Slide the ex- haust coupling (17) over the O-ring onto the exhaust gas connection fitting (2) (if the condensate trap is installed on a level with the heater, the drain (18) must be facing down). Engage the clamp (4) and screw tight. Tighten the drain (18). Assembling the roof cowl Fig. A3: Drill a hole with di- ameter 83 mm (any hollow compartments in the vicinity of the cowl hole should be lined with wood). Seal with rubber seal supplied (22). Coat textured surfaces with a plastic coachwork sealing agent (not silicon). If the roof cowl is relatively thick, first connect the ex- haust gas double duct from the outside onto the cowl. Slide the rubber seal (22) and clamp (4) onto the inner cowl section (23). First compress the exhaust duct (1) so that the coil windings are pressed against each other, then slide over the O-ring onto the con- nection fitting (24). Engage the clamp (4) and screw tight. Slide the air intake duct (5) onto the serrated connection fitting and secure with the black screw (25). Fasten the cowl section (23) with 6 bolts (26). Mount cowl roof (27) and secure using 2 bolts (28). Attention: The exhaust vents in the cowl roof must face at right-angles to the direction of travel. Always keep the cap (29) on when the heater is not operating. Double duct connection to the heating appliance Fig. A3: Press end of exhaust duct (1) together so that winding touches winding. Slide clamp (4) over exhaust duct (1). Pass the exhaust duct (1) via the O-ring and fit it to the exhaust coupling (17). Engage the exhaust duct tightener (4) onto the exhaust coupling (17) and secure. Take the connection fitting (19) with the wide side over the exhaust duct and slide it firm- ly onto the air connection fit- ting (6) on the heating unit. Line up the opening in the connection fitting (19) with the drain (18). Screw in and tighten connection fitting (20). Slide the air intake duct (5) firmly onto the connection fit- ting (19) and fasten with duct clamp (7). Drill a 10 mm diameter open- ing in the vehicle floor for the condensate hose (21). Fasten the condensate hose onto the connection fitting (20) and pass it through the opening. Attention: Due to the risk of frost in winter, the hose should not project more than 2 cm below the vehicle floor!

Under-floor assembly with wall cowl kit Refer to installation variant Fig. 5 (Page US 2). Install wall cowl on as flat a surface as possible on an out- side wall (vehicle apron) (refer to item 3 of interior installa- tion with wall cowl kit). Attention: If the wall cowl is installed using mounting brackets, or such, under the floor, the vehicle floor must be sealed tight (refer to item 6 of interior installation with floor cowl).

Interior installation with floor cowl Refer to installation variant Fig. 2 (Page US 2). When using the floor cowl al- ways observe any restric- tions given in the country- specific regulations. The appliance is only to be assembled in upright position. In vehicles designed for residential purposes or in vehicles with areas fre- quented by persons on a short-term basis, the vehi- cle floor must be sealed tight and is to have no openings to the interior, e.g. vent openings for refrig- erators, unsealed pedal open- ings, ventilation valves, hol- low double floors. The ventila- tion opening for the gas cylin- der box is not to be in the floor, it must be routed to the side, directly above the floor, through the outer wall. The floor cowl is not to lie within the splash range of the wheels (apply splash guard, if necessary) and it must be free-standing so as to prevent supports, axles, cross arms and such from impairing the correct operation. In addition, at least three sides beneath the vehicle floor must be open in order to ensure unhindered escape of the exhaust gas. Assembly of the floor cowl Fig. B1: The rectangular opening for the exhaust gas outlet (30) must be right-an- gles to the direction of travel. Attention: No modifications must be carried out to the floor cowl! Drill an 83 diameter opening in the vehicle floor. Coat the space between the cowl and the vehicle floor with plastic coachwork sealing agent (31) - do not use silicone! - Secure the floor cowl (32) with 4 screws (33).

Outside installation with floor cowl Refer to installation variant Fig. 4 (Page US 2). The appliance is only to be assembled with cowl connec- tion fitting pointing vertically down. The appliance can be installed on the outside of the vehicle, on a perpendicular wall (e.g. on the cab rear wall or on the body fire wall of a truck). In articulated vehicles always pay attention to suffi- cient spacing between the cab rear wall and the semi- trailer (observe rotary and ar- ticulation movements). Assembly of the floor cowl Fig. C: Slide the cowl (32) over the O-ring onto the ex- haust gas connection fitting (35) on the heating unit. The side-facing rectangular open- ings (30) must be at right-an- gles to the direction of travel. Apply four flange borings to the heater casing, drill through them with a short drill 2.5 mm in diameter and fasten the cowl with 4 screws (33)

Fastening the heating appliance Inside installation with wall cowl or roof cowl Fig. D: Depending on the in- stallation site, bolt the heating appliance securely with the fastening straps (a) or angle pieces (b) supplied. Inside installation with floor cowl Where a floor cowl is used, place the appliance on the cowl opening and screw tight with 4 angle pieces (see Fig.B2). Outside installation Fig. E: Assemble with the aid of the asembly mount. Fasten both mounts (36) securely and firmly to the vehicle with through bolts not less than M 5 in size. Fasten the U- beam (37) to the outside of the heater with the bolts sup- plied (38). Fasten the heater with 4 M 6 x 10 bolts (39) and self-locking nuts. Fasten two protective caps (40) to the outside of the vehicle. In order to drain condensa- tion water, drill a hole 8 mm in diameter at the lowest point in the heater casing some 20 mm from the edge. Ensure that the drill does not pene- trate more than 10 mm in or- der to prevent damage to any internal components. Fit the rubber connection fitting sup- plied (it projects about 4 cm downward). (Fig. C + E:d)

Warm air distribution and circulating air return with interior installation Warm air distribution Fig. F: The hot air (W) is ex- pelled from 2 vents, either di- rectly or via a hot air duct VR (diameter 72 mm). From the appliance to the first air outlet install only VR duct (72 mm diameter) with a maximum length of approx.

1.5 m. To prevent overheat-

ing, the first air outlet must be non-sealable (swivelling vent SCW 2, end support ENE). ÜR duct (65 mm diam- eter) can also be laid after the first air outlet. Hot air ducts whose surface temperature exceeds 80 degrees C (espe- cially as far as the first air out- let in the case of the E 4000) must be protected from con- tact by cladding with a duct insulator (such as Truma l 80). Secure all duct connections with self-tapping screws. Fas- ten ducts with clamps. The warm air system is de- signed for each type of vehi- cle individually, on a modular basis.

Circulating air return Fig. F: The circulating air (U) is sucked directly back into the appliance. If the heating appliance is in- stalled in a stowage compart- ment or similar, make an ap- propriately sized opening (ap- prox, 200 mm

) for circulating air feedback. Attention: Do not block air ducts to heating appliance.

Warm air supply and circulating air return with outside assembly Refer to installation vari- ants 4 + 5 (Page US 2). The warm air duct and recir- culating air duct between the heater and the vehicle - espe- cially in the area prone to stone demage - must be made from flexible LF air ducting or, in the protection zone, from LI air ducting (106 mm in diameter) A protective casing over the entire heater system protects it against damage and wea- ther conditions and simulta- neously serves as insulation. Fig. G1: Drill two openings with a diameter of 100 mm. Apply sealing agent to flange of both connector fittings (41) and bolt to the openings on the outside. Place the grid (47) in the recirculating air duct between the suction connection fitting and the ve- hicle wall. Thread LFS wire clamps (42) onto the air ducts (43). Slide the air ducts over the heater connection fittings (44) and the connector fit- tings (41) and fasten them with the LFS wire clamps (42). Seal the joints with sili- con paste. Fig. G2: Seal hollow double walls around the air duct by putting two rolled sheet metal strips (45) or lengths of pipe between 97 an 100 mm in di- ameter into the openings. Fig. G3: The warm air can be extended inside the vehicle using LI air duct (diameter 106 mm). To connect the air duct, fasten another conec- tion fitting (81) into the open- ing. The two connector fit- tings can be bolted together through the wall. Fig.G1: If you wish the warm air to be diffused inside the vehicle, an air diffuser (82) can be fitted over the warm air duct with 4 bolts. Attention: Do not close off or restrict the opening for the recirculating air duct! The air diffuser (46) has 2 con- nections for VR duct (72 mm diameter), neither of which must be closed off. The pro- tective metal sheet supplied (48) acts as a heat shield and must be securely fastened over the air diffuser (46). Stowage protection can be provided in the form of anoth- 12er protective metal sheet (49) fastened over the opening for the recirculating air duct (Accessory: Art. no. 39010- 11500). The warm air system is de- signed for each type of vehi- cle individually, on a modular basis. There is an extensive accessories program available (refer to brochure).

Fitting the Control panel Attention: When using Con- trol panels which are specific to the vehicle or manufactur- er, the electrical connection must be effected in accor- dance with Truma interface specifications. Any modifica- tion made to the Truma com- ponents pertaining to this will lead to the cancellation of the guarantee and to the exclusion of any claims for liability. The installer (manufacturer) is re- sponsible for providing oper- ating instructions for the user as well as for the labelling of the Control panels. When selecting the location, take note that the Control panels must not be subjected to any direct radiant heat. Length of the connection ca- ble 4 m or 10 m. If installation is only possible behind curtains or in similar locations with temperature fluctuations, a remote sensor for the ambient temperature must be used (special acces- sory). Installing the flush- fitted Control panel (available from 08/2002) Note: If it is not possible to instal the Control panel in a location flush with the sur- face, Truma can provide, on request, a surface-mounting frame (1) (Art. no. 40000- 52600) as a special accessory.

If installation flush with the surface is not possible, Truma can provide a surface mount- ing frame (15) (Art. no. 39050-11600) as a special accessory.

Fitting the electronic control unit

1. Fig. H4: Unscrew the cov-

er of the control unit. Attention: The plug on the electronic control unit should only be withdrawn or plugged in if the supply voltage had been disconnected before- hand. Pull the plug out straight.

2. Insert the plug on the Con-

trol panel cable (1) as shown in the diagram onto the red terminal strip of the control unit. Note: If a timer switch or a fine sensor is fitted, its plug is to be inserted on the red ter- minal strip. If several acces- sory components are being used at the same time, con- nection is effected via the multiple socket (Fig. H6: 6).

3. Secure the lower part with

two screws at an easily ac- cessible location, protected against moisture (must not be heated to above 65°C).

4. Screw the cover of the

control unit into place. If the appliance is assembled on the outside of the vehicle, the electronic control unit must be installed inside the vehicle, where it is protected against moisture and dam- age. Drill an opening of 25 mm diameter in the floor or wall, disconnect connector (Fig. H4: 2) of 20-pin cable form the control unit and pass through the opening. Seal with cable grommet. Re- insert connector. In special cases, the electron- ic control unit can be as-sem- bled on the outside of the ve- hicle, in a protective box, for the electronics on the outside (special equipment Art. no. 39950-00).

Electrical connection 12 V/24 V Electric cables, switching units and control units for heaters must be arranged in the vehicle in such a way that their satisfactory operation cannot be adversely affected under normal operating con- ditions. All cables leading to the outside must be splash proof at the leadthrough opening. Prior to working on elec- tric components the appli- ance must be disconnect- ed from the power supply. Switching off at the con- trol panel is not sufficient! When carrying out electric welding work on the body the appliance connection must be disconnected from the ve- hicle electrical system. Attention: If the connec- tions are transposed there is a risk of cable burning. This also rules out any guarantee or liability claims! The red cable is positive, the blue cable is negative! Connect the appliance to the fused vehicle electrical sys- tem (central electrical system

Do not connect any other consumers to the supply line! When using power packs, please observe that the appli- ance is only to be operated with safety extra-low voltage in accordance with EN 60742! Note: When connecting sev- eral appliances we recom- mend using the electronically controlled Truma Power Pack NT (230/12 V, 6 A, Art. no. 39900-01, or 230/24 V, 3 A, Art. no. 39900-02 Fig. H5). The Truma power pack is also suitable for trickle charging of lead-acid batteries (not for gel batteries!) Other chargers are only to be used with a car battery acting as buffer. When calculating the power requirement always consider the starting currents. The peak perform-ance of power packs can differ. A ripple con- tent U

≤ 1 V with load is still possible. Tip: For saving the battery we recommend using solar col- lectors. Please ask for infor- mation from your dealer.

Gas connection The gas supply line, diameter 8 mm, is connected to the connection fitting with olive couplings. Carefully hold in place with a second wrench when tightening! Attention: The gas connec- tion fitting on the appliance is not to be shortened or bent. Prior to connecting the appli- ance make sure that the gas lines are free from dirt, chips and such! Route the pipes in such a way that the appliance can be re- moved again for servicing. Keep the number of parting connections in the gas supply line in rooms frequented by people to a technically feasi- ble minimum. The gas system

must comply with the techni- cal and administrative rules and regulations of the respec- tive country of destination.

Function check After installation, check the gas supply line for leaks ac- cording to the pressure drop method. Then check all func- tions of the appliance, as specified in the operating in- structions. The operating in- structions are to be handed to the user, together with the completed warranty card. Take the nameplate of the operating instructions and installation instructions and adhere to a place on the appliance which is clearly visible and protect- ed against damage. The year of initial operation must be marked on the nameplate.

The manufacturer grants a warranty for malfunctions in the appliance which are based on material or produc- tion faults. In addition to this, the statutory warranty claims against the seller remain valid. A claim under warranty shall not pertain: - for parts subject to wear and in cases of natural wear and tear, - as a result of not original Truma parts being used in the appliance and as a result of unsuitable gas pressure regulators being used, - as a consequence of failure to respect Truma instruc- tions for installation and use, - as a consequence of im- proper handling, - as a consequence of im- proper transport packing, not arranged by Truma.

2. Scope of warranty

The warranty is valid for mal- functions as stated under item 1, which occur within 24 months after conclusion of the purchase agreement bet- ween the seller and the final consumer. The manufacturers will make good such defects by subsequent fulfilment, i.e. at their discretion either by re- pair or replacement. In the event of manufacturers pro- viding service under warranty, the term of the warranty shall not recommence anew with regard to the repaired or re- placed parts; rather, the old warranty period shall contin- ue to run. More extensive claims, in particular claims for compensatory damages by purchasers or third parties, shall be excluded. This does not affect the rules of the product liability law. The manufacturer shall bear the cost of employing the Truma customer service for the removal of a malfunction under warranty - in particular transportation costs, travel- ling expenses, job and materi- al costs, as long as the ser- vice is carried out in Ger- many. Customer service car- ried out abroad is not covered by the warranty. Additional costs based on complicated removal and in- stallation conditions of the appliance (e.g. removal of fur- niture or parts of the vehicle body) do not come under warranty.
