USER MANUAL Combi D 6 Trumatic

The Combi D diesel heater is a warm-air heater with integrated hot water boiler (10 litres volume). The burner operates fan-supported, which ensures trouble-free function even when on the move.

In winter operation the heater can be used to heat the room and simultaneously warm water. If only warm water is required, select summer operation.

• In summer operation, the water contents are heated in the smallest burner stage. Once the water temperature is reached, the burner switches off.
  In winter operation, the unit automatically selects the required power setting according to the temperature difference between the temperature set on the control panel and the current room temperature. When the boiler is filled, the water is automatically heated as well. The water temperature depends on the selected operational mode and the heater output.

At a temperature of approximately 3^ at the automatic FrostControl safety/drain valve, the valve will open and drain the boiler.

An additional altitude kit (part no. 34610-01) is required for long periods of heater operation at altitudes of 1500 to 2750m .

Safety instructions

In the event of a leak in the heater or the exhaust duct:

• use the rotary switch to switch off heater,
  open windows and door,
• ask an expert to inspect the entire system!

Repairs may only be carried out by an expert!

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.

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^) and to make sure that the area is well ventilated.

The system must comply with the respective regulations of the country in which it is used. National regulations and rules must be followed.

Absolutely no objects (e.g. spray cans) or flammable liquids are to be stored in the installation room or on the heater unit, since they may be exposed to increased temperature levels under certain conditions.

The exhaust system must be inspected by a qualified technician at regular intervals, not exceeding two years.

No work must be carried out on the heater, the exhaust duct or in the vicinity of the chimney while the unit is in operation.

Do not inhale exhaust fumes.

Before performing any work on the heater or the exhaust duct, switch off the heater and allow all parts to cool completely.

The heater must not be used during fuelling, or in enclosed car parks, in garages, or on ferries.

Do not operate the heater anywhere where flammable vapours or dust can form, e.g. in the vicinity of a fuel, carbon, wood or cereal storage facility or similar.

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 exhaust gas double duct (exhaust gas silencer and suction pipe) must be inspected regularly, particularly following long journeys, to check for any damage and to ensure that the connection is sound; the same applies to the mounting of the heater and the cowl.

The cowl and the combustion air infeed must be kept free of dirt (e.g. snow sludge, ice, foliage, etc.) at all times.

The hot air outlets and circulating / exhaust air intake openings must be unobstructed, to ensure that the heater is not at risk of overheating. The built-in temperature limiter blocks off the fuel supply when the heater becomes excessively hot.

Even outside the season, the heater should be operated once a month for about ten minutes.

When operational, the fuel display in the fuel tank must not be allowed to drop to the "low fuel" mark.

In the event that the vehicle fuel tank runs empty, the opening of the fuel removal duct is roughly at the same height as the surface of the fuel. In this state, and in particular when the fuel in the vehicle fuel tank slops around due to vehicle movement, a large amount of air is sucked in. This leads to an irregular supply of fuel to the heater. The heater burner is unable to maintain clean combustion in this condition, leading to the formation of smoke and odours.

A diesel heating system always needs more power than a similar gas heating system. If there is a requirement for an autarky of the same length (service life without external power supply), Truma recommends investigating whether it is possible to retrofit a larger and / or second battery.

Fuel supply

Fuel quality

The heater requires diesel fuel for its operation, as per DIN EN 590. Operation with biodiesel is not permitted (PME, RME or AME).

Fuel at low temperatures

The refineries and filling stations will automatically perform the required adjustments for standard winter temperatures (winter diesel).

Temperatures below 0^ can create difficulties if the vehicle still has summer diesel in its fuel tank.

If no special diesel fuel is available for use in low temperatures, e.g. winter diesel, then petroleum or benzine should be mixed in with the fuel, in accordance with the instructions given by the vehicle manufacturer.

Temperature

0°C to -20°C Winter diesel

-20 °C to -30 °C Polar or Arctic diesel

Used oil should not be used in a fuel mixture!

To guarantee that all fuel lines of the heater unit are filled with winter diesel or another permitted mixture after fuelling, the heater must be operated for at least fifteen minutes.

Operating instructions

Always observe the operating 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.

Before using for the first time, it is essential to flush the entire water supply system through with clean 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!

Materials in the device which come into contact with water are suitable for use with drinking water (see manufacturer declaration: www.truma.com - Downloads - Manufacturer Declaration).

Room thermostat

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.

i

i = Room temperature sensor

The thermostat setting on the control panel (1 - 5) must be determined individually depending on the heating requirement and the type of vehicle. For an average room temperature of about 23^ , we recommend a thermostat setting of about 4.

FrostControl

(safety/drain valve)

FrostControl is a currentless safety/drain valve. When there is a danger of frost, it automatically drains the contents of the boiler through a drainage muff. If excessive pressure is present in the system, pressure will be automatically intermittently equalized through the pressure relief valve.

k = rotary switch position "Operation" m = push button position "Closed"
n = push button position "Drain"
o = drainage muff
(led outside through floor of vehicle)

Closing the drain valve

Check if the rotary switch is set to "Operation" (position k), meaning that it is parallel to the water connection and engaged.

Close the drain valve by activating the push button. The push button must engage in position (m) "closed".

Only when the temperature around the drain valve is over around 7^ can it to be closed manually with the press button ("m" position) and the boiler filled.

Truma supplies a heating element (part no. 70070-01) as an accessory, which is inserted into the FrostControl and fixed in place with a retaining bracket. This heating element heats the FrostControl to approx. 10^ when the Combi is switched on. This means that the boiler can be filled after a shorter time, irrespective of the temperature in the installation compartment.

Automatic opening of the drain valve

If the temperature around the drain valve is below about 3^ it will open automatically and the push button will disengage (outward movement) ("n" position). The water from the boiler will be released through the drainage muff (o).

Manual opening of the drain valve

Turn the rotary switch by 180^ until it engages, whereby the push button moves out (position n). The water in the boiler drains out through the drainage muff (o).

The FrostControl drainage muff (o) must be free of contamination (slush, ice, leaves, etc.) at all times so the water can drain out easily! There shall be no claims under guarantee for damage caused by frost!

Initial start-up

(or when the fuel tank has run empty)

Filling the fuel lines

The heater normally has to be started up several times to fill the fuel lines if an automatic filling unit is not being used.

Connect unit to control panel to do this. The unit automatically performs 2 start attempts (initial start and repeat) per switch-on procedure with a run time of 2 minutes in each case. If no flame is detected after the repeat start, the unit switches to fault and has to be switched off and on again at the control panel.

After a total of 15 unsuccessful starting attempts (initial and repeat start) without forming a flame, the equipment is blocked. To remove the block, please contact the Truma Service Centre (see Service Booklet or www.truma.com).

Check fuel lines and connections for leaks after filling the fuel lines.

Taking into operation

Heating operation is basically possible without restriction with or without water content.

Check to make sure the cowl is unobstructed. Remove any covers that may be present.

Summer operation

(boiler operation only)

Move the rotary switch on the control panel to position (c - summer operation) 40^ or 60^ . The green (b) and yellow (g) LEDs light up.

After reaching the set water temperature (40^ or 60^) the burner will switch off and the yellow LED (g) will be extinguished.

Winter operation

Heating with water temperature monitoring

Set the rotary switch to the operational setting "e".

Set the rotary switch (a) to the desired thermostat setting (1 - 5). The green LED (b) for operation is lit and simultaneously indicates the position of the selected room temperature. The yellow LED (g) indicates the water's heat-up phase.

The unit automatically selects the required power level according to the temperature difference between the setting on the control panel and the current room temperature. 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^ . The yellow LED (g) will be extinguished after the water temperature is reached.

The warm air fan can continue to run in order to cool the unit (after-run).

Heating without water temperature monitoring

Set the rotary switch to the operational setting "d".

Turn the rotary switch (a) to the desired thermostat setting (1 - 5). The green LED (b) for operation is lit and simultaneously indicates the position of the selected room temperature. The yellow LED (g - water's heat-up phase) will be lit only when the water temperature is below 5^

The unit automatically selects the required power level according to the temperature difference between the setting on the control panel and the current room temperature. After reaching the room temperature set on the control panel, the burner will switch off. The warm-air fan will continue to run at a low speed as long as the blow-out temperature (on the unit) is higher than 40^ .

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.

Heating with drained water system

Set the rotary switch to the operational setting "d".

Turn the rotary switch (a) to the desired thermostat setting (1 - 5). The green LED (b) for operation is lit and simultaneously indicates the position of the selected room temperature. The yellow LED (g) will be lit only when the temperature of the unit is below 5^

The unit automatically selects the required power level according to the temperature difference between the setting on the control panel and the current room temperature. After reaching the room temperature set on the control panel, the burner will switch off.

Switching off

Use the rotary switch to switch off heater (position f). The green LED (b) goes off.

If the green LED (b) blinks after switching off, then the unit's after-running is active in order to reduce the unit's temperature. This will end after a few minutes and the green LED (b) will go off.

Always drain water contents if there is a risk of frost!

Red / yellow LED "failure"

A failure is indicated when the red LED (h) shines or when the red (h) or yellow LED (g) flashes.

Please consult the Trouble-Shooting list for possible causes.

A reset (fault reset) is carried out by switching off, waiting until all LED's on the control panel have stopped flashing, and then switching the heater on again.

If the window, to which a window switch is mounted, is opened, the heating device stops operating and the yellow LED (g) flashes 3 times. The heater continues operating when the window is closed.

Filling the water heater

Check if the rotary switch for the drain valve (FrostControl) is set to "Operation", meaning that it is parallel to the water connection and engaged.

Close the drain valve by pushing the push button until it engages.

When the temperature at FrostControl is below about 7^ , first switch on the heater to warm the installation compartment and FrostControl. After a few minutes, if the temperature around the FrostControl is more than about 7^ the drain valve can be closed.

Switch on the power for the water pump (either by the main switch or the pump switch).

Open hot water taps in kitchen and bathroom, (set preselecting mixing taps or single-lever fittings to "hot"). Leave the fittings open for as long as it takes for the boiler to displace the air and fill up, and the water to flow without interruption.

If only the cold water system is operated, without the boiler, the boiler still fills with water. To avoid frost damage, the boiler must be drained through the drain valve, even if it was not operated.

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

Switch off the power for the water pump (either by the main switch or the pump switch).

Open hot water taps in kitchen and bathroom.

Turn the rotary switch on the drain valve (FrostControl) by 180^ until it engages, whereby the push button moves out and the drain valve opens.

The boiler is now drained directly to the outside via the drain valve. Place a bucket beneath the outlet to check whether the water content has completely drained away (10 litres). There shall be no claims under guarantee for damage caused by frost!

Maintenance

Only original Truma parts may be used for maintenance and repair work.

Biofilm, deposits and limescale must be removed using chemicals to protect the unit from infestation by microorganisms. Only chloride-free products must be used in order to prevent damage to the unit.

The effectiveness of the use of chemicals to combat microorganisms in the unit can be increased by heating the water in the boiler to 70^ at regular intervals.

To do this, turn the rotary switch on the control panel to the 60^ (c - summer mode) position. The green (b) and yellow (g) LEDs light up.

Once the water in the boiler has reached a temperature of 60^ , the burner will switch off and the yellow LED (g) will go out. The unit must stay switched on for at least 30 minutes and no warm water may be removed. The residual heat in the heat exchanger will heat the water up to 70^ .

Fuses

The fuses are located in the electronic control unit, beneath the connector cover. When replacing a fuse, be sure to use the same type.

Device fuse: 10 A - slow - (T 10 A)

Burner fuse: 20 A - slow - 6.3 x 32 mm

Disposal

The heater unit must be disposed of in accordance with the administrative regulations of the country in which it is in use. National regulations and laws (in Germany, for example, the Altfahrzeug-Verordnung [old vehicle directive]) must be observed.

In other countries, the relevant regulations must be observed.
