USER MANUAL E 4000 A Trumatic

Symbols used Symbol indicates a possible hazard. Comment including information and tips.16 Items sensitive to heat (e.g. spray cans) must not be stored in the installation area, since excess temperatures may under certain circumstances be incurred there. Only pressure control equipment that complies with EN 12864 (in vehicles) and EN ISO 10239 (for boats) with a fixed delivery pressure of 30 mbar must be used for the gas system. The flow rate of the pressure control device must correspond to at least the maximum consumption of all devices installed by the system manufacturer. We recommend the Truma gas pressure control systems SecuMotion / MonoControl CS for vehicles and the Truma gas pressure control systems DuoComfort / DuoControl CS for dual-cylinder gas systems. We recommend the gas pressure control systems Truma SecuMotion / MonoControl CS for vehicles and the gas pres- sure control systems Truma DuoComfort / DuoControl CS for dual-cylinder gas systems. At temperatures of around 0 °C or less the gas pressure regu- lator and the changeover valve must be operated using the EisEx de-icing system. Controller connecting hoses that meet national regulations must always be used in the respective country for which the equipment is destined. These hoses must be checked regu- larly for brittleness. Winter-proof special hoses must always be used if the equipment is operated during the winter. If the pressure regulator is exposed to weather conditions – especially on trucks – always make sure to protect the regula- tor using the Truma protective cover (standard accessory in truck attachment kit). Important operating notes If the cowl has been placed near or directly beneath an open- ing window, the device must be equipped with an automatic shut-off device in order to prevent operation with the window open. 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 mounting of the appliance and the cowl. Following a blow-back (misfire) always have the ex-haust gas system checked by an expert! 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. Always keep the cowl for conducting exhaust gas and supply- ing combustion air, free from contamination (slush, leaves etc.). The installed temperature limiter shuts off the gas supply if the appliance becomes too hot. Therefore do not shut the warm air outlets and the opening for the returning circulating air. 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! Directive 2004/78/EC stipulates that a safety shut-off device is required if motor homes are being heated while driving. The Truma gas pressure control systems SecuMotion / MonoControl CS satisfy these requirements. If no safety shut-off device (e.g. for the Truma gas pres- sure control system SecuMotion / MonoControl CS) has been installed, the gas cylinder needs to be closed when driv- ing and appropriate signs must be displayed in the cylinder cupboard and close to the operating part. The safety shut-off device is also recommended for safety reasons if caravans are being heated while driving. For conducting the exhaust gas under the floor, the vehicle 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.). Instructions for mobile heating appliances Truma mobile cargo-hold heating units have been approved by the professional associations. They are complete 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 external connections of any kind. Approval covers only original mobile cargo-hold heaters manufactured by Truma. Reproductions by third parties have not been approved! Truma refuses to give any guarantee of safety and correct functioning in respect of a reproduction mobile cargo-hold heater. The use of the appliance in vehicles used for the transport of hazardous goods is not permitted.17 Always observe the opera ting instructions and “Impor- tant operating notes“ prior to starting! The vehicle owner is responsible for the correct operation of the appliance! The installer or vehicle owner must apply the yellow sticker with the warning information, which is enclosed with the ap- pliance, to a place in the vehicle where it is clearly visible to all users (e.g. on the wardrobe door)! Ask Truma to send you stickers, if necessary. Control panel with slide switch

Switching the heating on: Control panel with slide switch Set the switch (a) to Heating and switch (b) to the desired output setting. Control panel with rotary switch Set the rotary switch to the desired output setting (c). If the outside temperature is low, switch to high setting. The Trumatic E heater has been tested and approved for operation, also when the vehicle is moving. The burner with fan assistance guarantees satisfactory operation, even under extremely windy conditions. It may be necessary to ob- serve respective, country-specific regulations for the operation of liquid gas appliances when the vehicle is moving.

Operating instructions Switching on the Ventilation Control panel with slide switch Set switch (a) to Ventilation and switch (b) to the desired output setting. Control panel with rotary switch Set the rotary switch to the desired output setting (e). Switching off Set the slide switch (a) or the rotary switch (d) to the centre. If the appliance is switched off after a heating phase, the fan can continue running in order to make use of the residual heat. If the appliance is not used for a prolonged period of time, mount the cowl cap, close quick-acting valve in the gas sup- ply line and turn off gas cylinder. Green LED “Operating” (under rotary control knob) When the device is switched on (heating or ventilation), the green LED must light up (the fan is operational). If the LED does not shine, check the (main) switch. For this purpose ob- serve respective instructions of the vehicle manufacturer. During the heating process whilst the flame is burning, the green LED shines twice as brightly. This also makes it possible to determine the instantaneous switching point of the room temperature. Fuses The device and control panel fuses are on the electronic con- trol unit on the device. Device fuse (F1):

3.15 AT – slow – (EN 60127-2-3)

Control panel fuse (F3):

The fine-wire fuse must only be replaced by a fuse of the same design. Red LED “Failure” In the event of a failure, the red LED shines. Possible causes for the failure can be e.g. no gas, insufficient combustion air, heavily soiled rotor, defective fuse etc.. Deactivate by switch- ing off and then switching on again. Opening a window to which a window switch is attached and closing it again is the equivalent of switching the equip- ment off and on again at the control panel (e.g. a fault reset)! Flash operation indicates that the operating voltage is too low or too high for the appliance (charge battery, if necessary). In Germany, always notify the Truma Service Centre if prob- lems are encountered; in other countries the relevant service partners should be contacted (see Truma Service Booklet or www.truma.com). Disposal The device must be disposed of in line with the administra- tive regulations of the respective country in which it is used. National regulations and laws (in Germany, for example, the End-of-life Vehicle Regulation) must be observed.18 Accessories 1 Control unit VG 2 for heaters of driver's cabs in tank vehicles, for the trans- portation of hazardous goods according to ADR (not to be used in combination with a time switch). 2 Outside switch AS for switching the heater on and off from the outside of the vehicle, e.g. for cargo space heaters (available with 4 m or 10 m connecting cables). 3 Acoustic signalling device ASM gives an acoustic signal in event of a failure. 4 Time switch ZUE for pre-programming 3 switch-on times within 7 days, in- cluding 4 m connecting cable (suitable for 12 V and 24 V vehicle electrical system). 5 Remote sensor monitors the room temperature independent of the position of the control panel (available with 4 m or 10 m connecting cable). 6 Multiple connector MSD for connecting several accessories (e.g. time switch and remote sensor).

The manufacturer grants a warranty for malfunctions in the appliance which are based on material or production 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 using components in the units that are not original Truma parts, for gas pressure regulation systems as a result of damage by foreign substances (e.g. oils, plasticisers) in the gas, as a consequence of failure to respect Truma instructions for installation and use, as a consequence of improper handling, as a consequence of improper transport packing.

2. Scope of warranty

The warranty is valid for malfunctions as stated under item 1, which occur within 24 months after conclusion of the purchase agreement between the seller and the final con- sumer. The manufacturers will make good such defects by subsequent fulfilment, i.e. at their discretion either by repair or replacement. In the event of manufacturers providing service under warranty, the term of the warranty shall not recom- mence anew with regard to the repaired or replaced parts; rather, the old warranty period shall continue to run. More ex- tensive 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 war- ranty – in particular transportation costs, travelling expenses, job and material costs, as long as the service is carried out in Germany. The warranty does not cover customer service work in other countries. Additional costs based on complicated removal and installa- tion conditions of the appliance (e.g. removal of furniture or parts of the vehicle body) do not come under warranty.

3. Raising the case of warranty

The manufacturer‘s address is: Truma Gerätetechnik GmbH & Co. KG Wernher-von-Braun-Straße 12 85640 Putzbrunn, Germany Always notify the Truma Service Centre or one of our author- ised service partners if problems are encountered (see Truma Service book or www.truma.com). Please describe you com- plaint in detail and state the factory number of the device and the purchase date. In order for the manufacturer to be able to determine whether an incident subject to guarantee has occurred, the end user must, at his own risk, bring or send the device to the manu- facturer. If there is damage to heat exchangers, the gas pres- sure regulator must also be sent back to the factory. Air conditioners: To avoid transportation damage, the unit may only be sent to the Truma Service Centre Germany or one of our authorised service partners if agreed beforehand. Otherwise the sender bears the risk for any transportation damage. Please send all shipment to the factory as freight. In cases under guarantee, the works shall bear the transport costs or the costs of delivery and return. If the damage is deemed not to be a warranty case, the manufacturer shall notify the cus- tomer and shall specify repair costs which shall not be borne by the manufacturer; in this case, the customer shall also bear the shipping costs.

Check gas supply and open valves. Remove cowl cap. Inspect openings for contamination (slush, ice, leaves, etc.) and remove contamination if necessary.

After operating for a longer period of time, the heater switches to failure. Hot-air outlets blocked. Recirculated air intake blocked. Gas pressure regulator iced up.

If this does not solve the problem, please contact the Truma Service.21 The installation and repair of the appliance is only to be carried out by an expert. Read the installation instructions carefully prior to starting work and observe the instructions! Non-compliance with installation instructions or incorrect installation can result in endangerment of persons and property. Intended use This appliance has been designed for installation in vehicles (mobile homes, caravans, boats, trucks). Other applications are also possible following consul tation with Truma. Installation inside busses (vehicle classes M2 and M3) is not permitted. Vehicles for class EX/II and EX/III hazardous materials Combustion heaters for gaseous fuel are not permitted. Approval Directive 2004/78/EC stipulates that a safety shut-off device is required if motor homes are being heated while driving. The Truma gas pressure control systems SecuMotion / MonoControl CS satisfy these requirements. The installation of a safety shut-off device, such as e.g. the gas pressure control system Truma SecuMotion / MonoControl CS with the correct gas installation configura- tion, means that the operation of a type-approved liquid gas heating system when the vehicle is on the move is approved throughout Europe in accordance with the EC Directive 2001/56/EC. The safety shut-off device is also recommended for safety reasons if caravans are being heated while driving. The heater is approved for installation in motor vehicles for transporting passengers (motor caravans in vehicle class M1) that have no more than 8 seats excluding the driver’s seat, for trailers (caravans in vehicle class O) and for commercial vehi- cles (vehicle class N). The year when the equipment was first taken into oper- ation must be indicated with a check on the type plate. Installation instructions Regulations Guarantee claims, warranty claims and acceptance of liability will be ruled out in the event of the following: modifications to the unit (including accessories), modifications to the exhaust duct and the cowl, failure to use original Truma parts as replacement parts and accessories, failure to follow the installation and operating instructions. It also becomes illegal to use the appliance, and in some countries this even makes it illegal to use the vehicle. Installation in road vehicles must comply with the legal pro- visions of the country of use (e.g. for Europe EN 1949 for vehicles). National directives and regulations (e.g. DVGW worksheet G 607 for vehicles and G 608 for boats in Germany) must be complied with. In the case of vehicles used for commercial purposes, the respec- tive accident prevention regulations issued by the professional as- sociations are to be adhered to (e.g. for Germany BGV D 34). For further details on the rules and regulations in the respec- tive country of desig-nation, please contact our agencies abroad (see Truma Service Booklet or www.truma.com). Notes on the installation in commercial vehicles The TÜV-tested cylinder holder (part no. 39742-00) is a constituent of the type approval for Trumatic E heaters in accordance with heater directive 2001/56/EC. Here it is stated that 2 gas cylinders with a contents of max. 15 kg can be con- nected and used for operating the heaters while the vehicle is moving. For the protection of the cylinder valve and the gas pressure regula- tor, just the protective cover pro- vided with the cylinder bracket is required. For protection against theft or for reasons of appearance, the gas cylinder can also be concealed us- ing the lockable cylinder cabinet (part no. 39010-21100). The cabinet is bolted with the cylinder bracket to the vehicle frame. When installing the heater in special vehicles (e.g. vehicles for transporting hazardous goods), the respective regulations for such vehicles must be observed. Notes on installation in driver's cab In the case of heating systems where the waste gas is guided below the vehicle floor, the waste gas cowl outlet must be attached up to the side or rear edge of the driver‘s cab or the vehicle. Steps must be taken to ensure that no waste gases can enter the inside of the vehicle (e.g. from below through the vehicle floor). Model-related assembly instructions can be obtained from Truma. In Germany, for tank vehicles carrying hazardous goods in the field of application covered by the ADR, the appliance is only approved with the Truma control unit.

–22 Assembly instructions for permanently mounted trunk compartment heating systems Please observe the Truma assembly instructions “Additional truck heating systems” and “Trunk compartment heating sys- tem E 4000 A” when using as a truck compartment heating system. In the case of vehicles used for commercial purposes, the respective accident prevention regulations issued by the pro- fessional associations are to be adhered to (e.g. for Germany BGV D 34). The assembly instructions “Trunk compartment heating sys- tem E 4000 A” includes a form for the required “Confirmation of installation by a specialist company”. Notes on installation in boats Installation in boats must comply with the legal provisions of the country of use (e.g. EN ISO 10239). National specifications and regulations (in Germany, for example, DVGW Worksheet G 608) must be respected. The “Guidelines for the Construction, Installation, Testing and Operation of Liquid Gas Systems for Household Purposes on In- land Waterways” (BGR 146) must be complied with in Germany. According to these guidelines the liquid gas system must be installed by an engineer who has been approved by the inland waterways employer’s liability associations and tested by experts belonging to these employer’s liability insurance associations. In other countries always observe the respectively valid regulations. For further notes on installation, refer to the assembly instruc- tions 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 accessible for service work and can be removed and installed easily. For evenly distributed heating, the installation of the appliance should be as much in the centre of the vehicle as possible (or under the vehicle), and in such a way that the air distribu- tion ducts can be routed with approximately the same length. Cowls must always be fitted to prevent any waste gases en- tering the inside of the vehicle. The waste gas must always be guided to at least a side wall. The wall cowl must be attached so that no tank supports or tank ventilation openings are found within 500 mm (R). In addition, no air discharge apertures for the living area or window openings may be located with 300 mm (R) of it.

When fitting the cowl within the marked area below or next to a window that must be open, an electrical window switch (part no. 34000-85800) must be installed. The gas unit must automatically switch itself off using the Truma automatic shut-off facility if the window is opened (Accessories, part no. 39050-00800). 300 mm 300 mm Notes on skylights With skylights (opening) the cowl top must project at least 10 cm above the opened window. If the cowl is located beside the window, it is important to ensure that, depending on the installation position (opening to the right or to the left), no exhaust gases can enter the open window (e.g. through wind) and that the cowl has sufficient draught air. If the cowl is installed in the vicinity of the skylight, the instal- lation of an electric window switch is compulsory (part no. 34000-85800). The gas unit must automatically switch itself off using the Truma automatic shut-off facility if the window is opened (Accessories, part no. 39050-00800). Notes on water supply When installing a water supply into the vehicle, please ensure that there is an adequate distance between the water hoses and the heat source (e.g. heater, warm air duct). A water hose may only be fitted at a clearance of 1.5 m to the heater on the warm air duct. The Truma hose clip SC (part no. 40712-01) can be used if this distance is observed. In the case of parallel installations, e.g. openings through a wall, a spacer element should also be attached (e.g. insulation) to prevent contact. Exhaust duct Trumatic E 4000 (A) heaters with wall or roof cowl must be installed only with Truma exhaust duct AA 3 (part no. 39320-00) – or Truma high-quality steel exhaust duct AEM 3 (part no. 39360-00) for boats – and air intake duct ZR (part no. 39580-00), because the appliances have only been tested and approved with these ducts. New O-rings must installed each time the appliance has been dismantled. Permitted duct lengths

1. Inside installation with wall cowl

(see installation variant 1, page 2): – Duct lengths up to max. 30 cm can be laid horizontally 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.

Ducts must also be protected against damage from flying stones.23 Inside installation with wall cowl set See installation variant Fig. 1 (page 2) Installation of wall cowl Install wall cowl (arrow pointing up) on an even surface around which wind can flow from all sides. Drill an opening of 83 mm diame ter (pack wood into any hol low spaces in the area of the cowl opening). Use the en closed rubber seal (8) for sealing. In the event of structured surfaces coat with plastic body seal- ant – do not use silicone! Slide clamp (7) over the ducts prior to passing the exhaust double duct through the opening. Slide rubber seal (8 – smooth side toward cowl, sealing lips toward wall) and clip (4) onto inner section of cowl (9). Press together end of exhaust duct (1) so that winding touch- es winding, and slide over O-ring (10) onto the connection fitting (11 – bend pointing up). Slide holes of clip (4) onto pins of muff (11 – screw facing downwards) and screw in place. Slide combustion air intake duct (5) on the serrated connection fitting (12). Fasten cowl inner part (9) with 6 self-tapping screws (14), mount cowl outer part (15) and fasten with 2 screws (16). Fasten combustion air intake duct with clamp (7), from the inside, on the connection fitting (12). Fasten cowl double duct to the wall with at least one clamp ZRS (17).

Slide the clamp (4) over the exhaust duct (1). Slide the exhaust duct onto the connection fitting (2) over the O-ring. Engage the clamp (4) and screw tight. Secure the air intake duct (5) on the connection fitting (6) with clamp (7). Inside installation with roof cowl set See installation variant Fig. 2 (page 2). Install roof cowl on a surface which is as straight as possible, with wind flow from all sides. From the appliance to the cowl it must be possible to have a direct duct route rising over the entire duct length (max. 2 m)! Assembling the condensate trap A condensate trap has to be in- stalled between the heater and the double duct to allow condensation water and rain water to drain away. The exhaust gas double duct must not sag – the conden- sate trap must be the lowest point! Fully open the clamp (4) and slide over the O-ring onto the exhaust gas connection fitting (2). Slide the exhaust coupling (17) over the O-ring onto the exhaust gas con- nection fitting (2 – if the conden- sate 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 Drill a hole (8) with diameter 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 exhaust 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 connection fitting (24). Engage the clamp (4) and screw tight. Slide the air intake duct (5) onto the serrated connection fit- ting 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). 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 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 fit- ting (19) with the wide side over the exhaust duct and slide it firmly onto the air connection fitting (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 fitting (19) and fasten with duct clamp (7). Drill a 10 mm diameter opening in the vehicle floor for the condensate hose (21). Fasten the condensate hose onto the connection fitting (20) and pass it through the opening. Due to the risk of frost in winter, the hose should not project more than 2 cm below the vehicle floor!24 Under-floor assembly with wall cowl kit Refer to installation variant Fig. 4 (page 2). Cowls must always be fitted to prevent any waste gases en- tering the inside of the vehicle. The waste gas must always be guided to at least a side wall (see “Choice of location”). Fastening the heating appliance Assemble with the aid of the asembly mount. Fasten both mounts (36) securely and firmly to the vehicle with through bolts not less than M5 in size. Fasten the U-beam (37) to the outside of the heater with the bolts supplied (38). Fasten the heater with 4 M6 x 10 bolts (39) and self-locking nuts. Fasten two protective caps (40) to the outside of the vehicle. In order to drain condensation water, drill a hole 8 mm in di- ameter at the lowest point in the heater casing some 20 mm from the edge. Ensure that the drill does not penetrate more than 10 mm in order to prevent damage to any internal com- ponents. Insert the rubber grommet (d) supplied (it extends about 4 cm downwards). Outside assembly with cowl pipes See installation variant Picture 3 (page 2) and the Truma as- sembly instructions “Additional truck heating systems” and “Trunk compartment heating system E 4000 A”. Fastening the heating appliance Inside installation with wall cowl or roof cowl Depending on the installation site, bolt the heating appli- ance securely with the fastening straps (a) or angle pieces (b) supplied. Warm air distribution and circulating air return with interior installation Warm air distribution Warm 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 construction 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 installations and for external installations. (In heaters with fresh air operation the fresh air is not to come from the engine compartment, from the vicinity of the exhaust or the exhaust outlet of the heater.) The warm air (W) is expelled from 2 vents, either directly or via a warm air duct VR 72 (diameter 72 mm). From the appliance to the first air outlet install only VR 72 duct (72 mm diameter) with a maximum length of approx. 1.5 m. To prevent overheating, the first air outlet must be non- sealable (swivelling vent SCW 2, end support EN-O). ÜR duct 65 mm diameter) can also be laid after the first air outlet. Hot air ducts whose surface temperature exceeds 80 °C (especially as far as the first air outlet in the case of the E 4000) must be protected from contact by cladding with a duct insulator (such as Truma l 80). Secure all duct connections with self-tapping screws. Fasten ducts with clamps. The warm air system is designed for each type of vehicle indi- vidually, on a modular basis. There is an extensive accessories program available (refer to brochure). Diagrams with optimum installation suggestions for warm air systems in all of the most popular motor home models can be requested free of charge via the Truma service centre. Circulating air return The circulating air (U) is sucked directly back into the appliance. If the heating appliance is installed in a stowage compartment or similar, make an appropriately sized opening (approx, 200 cm

for circulating air feedback. Do not block air ducts to heating appliance! Warm air supply and circulating air return with outside assembly Refer to installation variants Fig. 3 + 4 (Page 2). The warm air duct and recirculating air duct between the heater and the vehicle – especially 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 weather conditions and simultaneously serves as insulation.25 Drill two openings with a diameter of 100 mm. Apply sealing agent to flange of both connector fit- tings (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 vehicle wall. Thread LFS wire clamps (42) onto the air ducts (43). Slide the air ducts over the heater connection fittings (44) and the con- nector fittings (41) and fasten them with the LFS wire clamps (42). Seal the joints with silicon paste. 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 diameter into the openings. The warm air can be extended inside the vehicle using LI air duct (diameter 106 mm). To connect the air duct, fasten another connec- tion fitting (41) into the opening. The two connector fittings can be bolted together through the wall. If you wish the warm air to be diffused inside the vehicle, an air diffuser (46) can be fitted over the warm air duct (W) with 4 bolts. Do not close off or restrict the opening for the recircu- lating air duct! The air diffuser (46) has 2 connections for VR 72 duct (72 mm diameter), neither of which must be closed off. The protective metal sheet supplied (48) acts as a heat shield and must be securely fastened over the air diffuser (46). Stowage protec- tion can be provided in the form of another protective metal sheet (49) fastened over the opening for the recirculating air duct (Accessory, part no. 39010-11500). The warm air system is designed for each type of vehicle indi- vidually, on a modular basis. There is an extensive accessories program available (refer to brochure). Diagrams with optimum installation suggestions for warm air systems in all of the most popular motor home models can be requested free of charge via the Truma service centre. Fitting the control panel When using control panels which are specific to the vehicle or manufacturer, the electrical connection must be effected in accordance with Truma interface specifications. Any modification made to the Truma components pertaining to this will lead to the cancellation of the guarantee and to the exclusion of any claims for liability. The installer (manufacturer) is responsible for providing operating 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 cable 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 (Accessories). Installing the control panel with rotary switch If flush mounting is not possible, Truma will supply an on-surface frame (1 – part no. 40000-52600) as an acces- sory on request. Drill a hole 55 mm in diameter. Plug the control panel cable (2) into the control panel (3) and then fit the rear cover cap (4) as a stress-relieving device. Push the cable through to the rear and lay it to the electronic control unit. Ø 55 mm
