To be kept in the vehicle! Cold water connection Hot water connection Gas connection Hot air outlets Circulating air return line Waste gas discharge Combustion air infeed Electronic control unit Cover for connection cable 10 Water container (12 l) Function description The Trumatic C is a hot-air liquid-gas heating system with integrated hot water boiler (12 litres content). The burner operates fan-supported, which ensures troublefree function even when on the move. National restrictions must be observed with regard to operation when on the move. In winter operation (heating and hot water) the device automatically selects the output level required, depending on the temperature difference between the room temperature which has been set and the temperature at the particular time. The Type C 6002 operates at three output stages (2000, 4000, and 6000 W), and the Type C 3402 at two stages (2000 and 3400 W). With the boiler filled, the water will be automatically heated at the same time. The water temperature is dependent on the operating mode selected (with or

Igniter Burner Heat exchanger Overheating protector Temperature sensor 230 V heating collar for hot water (Trumatic C EL only) 17 Control panels 18 Room temperature sensor without hot water requirement) and on the heating output yield. Heating operation is basically possible without restriction with or without water content. In summer operation (hot water only), the heating of the water content takes place at the lowest burner stage. Once the water temperature has been reached, the burner switches off and the yellow monitor lamp goes out. Trumatic C EL units have an additional 230 V electric heating capability available as an option (450 W/2 A) for hot water. Important operating notes shut the warm air outlets and the opening for the returning circulating air.

1. 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.

6. According to § 22a of the

StVZO the heat exchangers of liquid gas heaters built into vehicles only have to be replaced after 30 years in Germany (the first year of use must be indelibly marked on the type 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 mounting of the appliance and the cowl. Always use original Truma spare parts for maintenance and repair work.

3. Following a blow-back

(misfire) always have the exhaust gas system checked by an expert!

4. Always keep the cowl for

the exhaust duct and combustion air intake free of contamination (slush, ice, leaves etc.).

5. The installed temperature

limiter shuts off the gas supply if the appliance becomes too hot. Therefore do not

Before using for the first time, it is essential to flush the entire water supply through with clean warm water. If the heater is not being used, always drain the water contents if there is a risk of frost. There shall be no claims under guarantee for damage caused by frost! Also drain the water prior to repair or maintenance work on the vehicle (in the workshop!) as the electrical safety/drain valve opens when the appliance is switched dead. Electrical safety/drain valve m= Control knob „closed“ n = Control knob „drain“ The safety/drain valve is held closed by a electrical coil. To save battery power, we recommend to open the valve if the vehicle is not in use for a prolonged period! If the temperature at the safety/drain valve is less than 4°C, the water contents may discharge on its own accord if the appliance is not in operation (also if there is a failure)! To avoid water loss, switch the device on (summer or winter operation) and close the safety/drain valve at the actuating button by raising it up (position m).

Filling the water heater

1. Close electrical safety/

drain valve at the control knob by lifting up (position m). At temperatures of around 8°C and less, switch on the heater or water heater first, to make sure the valve does not open again!

2. Switch on power for water

pump (main switch or pump switch).

3. Open hot water taps in

kitchen and bathroom, (set preselecting mixing taps or single-lever fittings to „hot“). Leave taps open until the water heater has forced out air and filled up with water and water is flowing out of the taps. If just the cold water system is being operated, without using the water heater, the heater tank also fills up with water. In order to avoid damage by frost, the water contents must be drained by operating the safety/drain valve, also when the water heater has not been used. As an alternative, two shutoff valves, resistant to hot water, can be fitted in front of the cold and hot water connection. When connecting to a central water supply (rural or city mains), a pressure reduction valve must always be installed to prevent pressures above 2.8 bar from developing in the water heater. Draining the water heater

1. Interrupt power for water

pump (main switch or pump switch).

2. Open hot water taps in

kitchen and bathroom.

3. Open electrical safety/drain

valve at control knob by pressing in (position n). Gas operation (heating and hot water) Trumatic C

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. The draining socket of the electrical safety/drain valve must always be kept clear (free from slush, ice, leaves etc.)! There shall be no claims under guarantee for damage caused by frost! The water heater content is now emptied to the outside through the safety/drain valve. Place a bucket beneath the outlet to check whether the water content has completely drained away (12 litres). There shall be no claims under guarantee for damage caused by frost!

Always observe the operating instructions and „Important operating notes“ prior to starting! The vehicle owner is responsible for the correct operation of the appliance. Without heater operation, the safety/drain valve can only be closed again at temperatures above 8°C!

Room thermostat

Taking into operation

1. Check that the cowl is not

obstructed. Always remove any covers, open deck cowl on boats. In winter, if a roof cowl is fitted, it is recommended that a cowl extension be fitted (see Accessories). This must be removed when the vehicle is on the move. To run the cowl through the roof on a caravan, a cowl extension piece is likewise used, which must be fixed to the roof with clamp rings (see Accessories).

2. Turn on gas cylinder and

open quick-acting valve in the gas supply line. Heating operation is basically possible without restriction with or without water content. Summer operation (hot water only) Set the rotary switch to Summer operation (c), 40°C or 60°C. Once the water temperature which has been set (40°C or 60°C) has been reached, the burner will switch off and the yellow monitor lamp (g) will go out. Winter operation Heating with hot water requirement

1. Set the rotary switch (a) to

the desired thermostat setting (1 – 9). When the system is switched on, the green monitor lamp (b) will light up, and shows the setting for the room temperature. i = Room temperature sensor To measure the room temperature, an external room temperature sensor (i) is located in the vehicle. The location of the sensor is determined individually by the vehicle manufacturer, depending on the vehicle type; consult the operating instructions for your vehicle for further details. The thermostat setting on the control panel (1 – 9) must be determined individually depending on the heating requirement and the type of vehicle. For an average room temperature of about 23°C, we recommend a thermostat setting of about 6 – 8.

2. Set the rotary switch to the

operational setting „e“. The device automatically selects the output stage required, depending on the temperature difference between the room temperature which has been set and the temperature at the particular time. Once the room temperature set on the control panel has been reached, the burner switches back to the lowest stage, and heats the water content to 60°C. The yellow monitor lamp (g) indicates the heating-up phase is in progress, and goes out once the appropriate water temperature has been reached. Heating without hot water requirement

1. Turn the rotary switch (a)

to the desired thermostat setting (1 – 9). When the system is switched on, the green monitor lamp (b) will light up, and shows the setting for the room temperature.

2. Set the rotary switch to the

operational setting „d“. The device automatically selects the output stage required, depending on the temperature difference between the room temperature which has been set and the temperature at the particular time. Once the room temperature set on the control panel has been reached, the heating will switch off (regardless of the water temperature). If the boiler is filled, the water will automatically be heated at the same time. The water temperature is then dependent on the heating output being given off, and the duration of heating required to reach the desired room temperature. In this operational mode, the yellow monitor lamp (g – Boiler Heat-up Phase) only lights up if the water temperature is below 5°C. Heating operation is basically possible without restriction with or without water content. Switching off „Gas operation“ Switch heating system off at the rotary switch (f). Always drain water contents if there is a risk of frost! If the appliance is not to be used for a prolonged period, close the quick-acting valve in the gas supply line and turn off the gas cylinder. Red indicator lamp „Failure“ In the event of a fault, the red monitor lamp (h) will light up. Please consult the TroubleShooting list for possible causes. Release is effected by switching the system off and then on again. Opening the window switch and closing it again is the equivalent to switching off/on at the control panel (e.g. performing a fault reset)! 230 V electrical operation (450 W/2 A) – Trumatic C EL only – (hot water only) Trumatic C EL

230 V ~ j = Rocker switch „On“ k = Rocker switch „Off“ Switch boiler on at the operating point (j). The indicator lamp indicates that the device is in operation. When using vehicle-specific switches: refer to operating instructions of vehicle manufacturer. The water temperature cannot be selected, automatic temperature limitation at approx. 60°C! For a faster heating up period the appliance can be simultaneously operated with gas and electrical power. Maintenance The water container used is made of stainless steel, which is foodstuff-compatible. Use wine vinegar for descaling the water heater, this being introduced into the appliance via the water supply. Allow the product to react and then thoroughly flush out the appliance with plenty of fresh water. To sterilise the water we recommend „Certisil-Argento“. Other products, particularly those containing chlorine are unsuitable. To avoid infestation by microorganisms, the boiler must be heated to 70°C at regular intervals (only possible in winter operation). The water can be heated to up to 70°C depending on the heating power that is required to achieve the room temperature. Do not use the water as drinking water! Fuses The fuse for the device is located on the electronic control unit. The fine-wire fuse must only be replaced by a fuse of the same design. C 3402: 4 AT – slow-acting – C 6002: 6,3 AT – slow-acting – General safety notes 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!

1. Any alteration to the appliance (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 vehicle.

2. 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 operating pressure of the appliance (see name plate).

3. Liquid gas systems must

comply with the technical and administrative regulations of the respective country of use (e.g. EN 1949 for vehicles or EN ISO 10239 for boats in Europe). National directives and regulations (e.g. DVGW worksheet G 607 for vehicles and G 608 for boats in Germany) must be complied with. The testing of the gas system must be repeated every two years by a qualified specialist and, if appropriate, confirmed on the inspection certificate (in Germany, f. ex. DVGW Worksheet G 607 for motor vehicles or G 608 for boats). The vehicle owner is always responsible for arranging the inspection.

4. Liquid gas equipment must

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

5. 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. It is a good idea to heat the device up several times in summer operation (60°C) and to make sure that the area is well ventilated.

6. 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.

7. 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.

8. 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 (or 50 mbar in older systems) 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. For vehicles we recommend the Truma caravan regulator and the Duomatic Plus gas pressure regulator kit for the two-bottle system. Truma regulators have been specially developed for the harsh stress conditions in caravans and vehicles. As well as a safety valve that provides protection against overpressure, they also have a pressure gauge that can be used to check the tightness of the gas system. The pressure control equipment should be operated with a de-icing system (Eis-Ex) at temperatures around 0°C and below. 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.
