Safety instructions

The use of upright gas cylinders from which gas is taken in the gas phase is mandatory for the operation of gas regulators, gas equipment and gas systems. Gas cylinders from which gas is taken in the liquid phase (e.g. for fork lifts) must not be used, since they would result in damage to the gas system.

If the gas system is leaking 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 windows and door
  – do not actuate any electrical switches
  – have the entire system checked by an expert!

Repairs may only be carried out by an expert!

A new O-ring must always be installed after dismantling the exhaust duct!

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.

The gas supply's operating pressure (30 mbar) must be the same as the unit's operating pressure (see type plate).

Liquid gas systems must comply with the legal provisions of the country in which they are put to use (e.g. for Europe EN 1949 for vehicles and EN ISO 10239 for boats). 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 respective accident prevention regulations issued by the professional associations are to be adhered to (e.g. for Germany BGV D 34).

The inspection of the gas system is to be repeated every two years by am approved liquid gas specialist (DVFG, TÜV, DEKRA). This is to be confirmed on the corresponding inspection certificate (G 607, G 608, or BGG 935).

The vehicle owner is always responsible for arranging the inspection.

Pressure regulating devices and hoses must be replaced with new ones no more than 10 years after their date of manufacture (every 8 years if used commercially). This is the responsibility of the operator.

Liquid gas equipment must not be used when refuelling, in multi-storey car parks, in garages or on ferries.

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 output and ensuring adequate room ventilation.

If the burner makes an unusual noise or if the flame lifts off, it is likely that the regulator is faulty and it is essential to have it checked.

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 pressure control systems Truma DuoComfort / DuoControl CS for dual-cylinder gas systems.

At temperatures of around 0 °C or less the gas pressure regulator 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 regularly 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 regulator 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 opening 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 supplying 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 pressure control system SecuMotion / MonoControl CS) has been installed, the gas cylinder needs to be closed when driving 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 independent 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.

Operating instructions

Always observe the opera ting instructions and "Important 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 appliance, 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.

• Adjust desired room temperature at rotary knob.
  – 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 observe respective, country-specific regulations for the operation of liquid gas appliances when the vehicle is moving.

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 supply 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 observe 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 control unit on the device.

Device fuse (F1):

3.15 AT - slow - (EN 60127-2-3)

Control panel fuse (F3):

1.6 AT - slow -

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 switching 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 equipment 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 problems 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 administrative 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.

Manufacturer's terms of warranty

1. Case of warranty

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 consumer. 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 recommence anew with regard to the repaired or replaced parts; rather, the old warranty period shall continue 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, 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 installation 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:

The “Guidelines for the Construction, Installation, Testing and Operation of Liquid Gas Systems for Household Purposes on Inland 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 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 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 distribution ducts can be routed with approximately the same length.

Cowls must always be fitted to prevent any waste gases entering the inside of the vehicle. The waste gas must always be guided to at least a side wall.

Technical line drawing of a vehicle wheel assembly with a close-up view of the internal components (no text or symbols)

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 installation 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.

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).

Technical diagram of a mechanical device with labeled components U and W, showing internal wiring and shafts.

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). UR 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 I 80). Secure all duct connections with self-tapping screws. Fasten ducts with clamps.

The warm air system is designed for each type of vehicle individually, 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 ^4 ) 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 damage – 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.

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 vehicle wall. Thread LFS wire clamps (42) onto the air ducts (43). Slide the air ducts over the heater connection fittings (44) and the connector 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.

W 45 W U

The warm air can be extended inside the vehicle using LI air duct (diameter 106 mm). To connect the air duct, fasten another connection 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 recirculating 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 protection 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 individually, 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).

If a timer switch or a fine sensor is fitted, its plug is to be inserted on the red terminal strip. If several accessory components are being used at the same time, connection is effected via the multiple socket (Accessory).

Secure the lower part with two screws at an easily accessible location, protected against moisture (must not be heated to above 65 °C).

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 damage. Drill an opening of 25 mm diameter in the floor or wall, disconnect connector (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 electronic control unit can be assembled on the outside of the vehicle, in a protective box, for the electronics on the outside (accessory, part 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 conditions. All cables leading to the outside must be splash proof at the leadthrough opening.

Prior to working on electric components the appliance must be disconnected from the power supply. Switching off at the control panel is not sufficient!

When carrying out electric welding work on the body the appliance connection must be disconnected from the vehicle electrical system.

If the connections are transposed there is a risk of cable burning. This also rules out any guarantee or liability s!

The red cable is positive, the blue cable is negative!

Connect the appliance to the fused vehicle electrical system (central electrical system 5 – 10 A) using the 2 x 1.5 mm ^2 cable, for lengths over 6 m use 2 x 2.5 mm ^2 cable. Negative cable to central ground. For direct connection to the battery the positive and negative cable must be fused. Connections in Faston terminals, fully insulated (motor vehicle flat connector system, 6.3 mm).

Do not connect any other consumers to the supply line!

When power packs or power supply units are being used, note that the output voltage is between 11 V and 15 V the alternating current ripple is < 1.2 Vpp. We recommend the automatic chargers from Truma for the different options. Please ask your dealer. Other chargers may be used with a 12 V battery as a buffer.

Gas connection

The gas supply's operating pressure (30 mbar) must be the same as the unit's operating pressure (see type

The 8 mm diameter gas supply pipe must be attached to the connecting piece with a cutting ring connection. Carefully counterhold with another spanner when tightening!

The gas connecti on fitting on the appliance is not to be shortened or bent.

Prior to connecting the appliance make sure that the gas lines are free from dirt, chips and such!

Choose to route the pipes in a way that will facilitate removing the unit for service tasks.

Keep the number of parting connections in the gas supply line in rooms frequented by people to a technically feasible minimum.

The gas system must accord with the technical and administrative provisions of the individual country of use (in Europe, for example, EN 1949 for motor vehicles or EN ISO 10239 for boats). National regulations and rulings (in Germany, for example, the DVGW worksheet G 607 for motor vehicles or G 608 for boats) must be respected.

Function check

After installation, the gas feed line must be tested for tightness by the pressure-drop method. A test certificate (in Germany, for example, in accordance with DVGW Worksheet G 607 for motor vehicles or G 608 for boats) is to be issued.

All equipment functions must be tested in accordance with the user manual after installation.

The operating instructions must be handed to the owner of the vehicle.

Remove the type plate from the operating and installation instructions and affix it at a position on the heater which arly visible and well protected against damage. The year tial operation must be marked on the type plate.
