Q: Which filters of the TRUMA Aventa comfort are washable and how to clean them?

The TRUMA Aventa comfort has washable air filters that need to be regularly maintained to keep cooling performance. Cleaning procedure Remove the front panel of the unit Take out the filter Wash it with lukewarm soapy water Let it dry completely before reinstalling Maintenance frequency Replace the filters at least every 12 months , depending on usage intensity. A clogged filter reduces airflow and limits cooling efficiency. Important point Never operate the air conditioning without a filter, as this can cause a loss of power. For a complete replacement, use the original filter set no. 40091-16800 (2 units).

Question 1

Where is the safety device or fuse for the TRUMA Ultraheat heater?

Accepted Answer

The TRUMA Ultraheat does not have an internal fuse accessible to the user. Electrical protection is provided at the external level, on two levels:

1. Protection of the camping connection

If your Ultraheat is powered via the 230V~ camping socket, the protective fuse or circuit breaker is located in the electrical panel of the camping site. The power must correspond to the site's fuse value:

500W: consumption 2.2A
1000W: consumption 4.5A
2000W: consumption 8.5A

2. Protection of the vehicle or caravan

If the device is installed in a vehicle or caravan, the residual current circuit breaker (RCCB) or fuse is located in the 230V distribution panel of the vehicle, usually near the battery or in the electrical compartment.

Important point

Warning: Any opening of the Ultraheat casing or internal manipulation is strictly reserved for qualified Truma personnel. Before any intervention, completely disconnect the device from the 230V network on all poles. Unauthorized modifications void the warranty and compliance.

If a safety device triggers regularly, contact a certified Truma installer for diagnosis.

Question 2

Which filters of the TRUMA Aventa comfort are washable and how to clean them?

Accepted Answer

The TRUMA Aventa comfort has washable air filters that need to be regularly maintained to keep cooling performance.

Cleaning procedure

Remove the front panel of the unit
Take out the filter
Wash it with lukewarm soapy water
Let it dry completely before reinstalling

Maintenance frequency

Replace the filters at least every 12 months, depending on usage intensity. A clogged filter reduces airflow and limits cooling efficiency.

Important point

Never operate the air conditioning without a filter, as this can cause a loss of power. For a complete replacement, use the original filter set no. 40091-16800 (2 units).

Question 3

Why is my TRUMA Aventa comfort not cooling sufficiently?

Accepted Answer

If your Truma Aventa comfort is not cooling sufficiently, first check these essential points:

Clogged filters – This is the main cause. Replace the filters according to usage, at least every 12 months. Operating without a filter significantly reduces airflow to 400 m³/h and cooling performance. Use filter set no. 40091-16800 (2 pieces).
Blocked airways – Check that the air inlets/outlets on the roof and facade are not blocked by foliage, dust, or debris. Clean the grilles and ducts regularly.
Suboptimal settings – Set the fan to maximum (not medium), adjust the front/rear distribution to the middle position, and the ceiling/floor to ceiling for better circulation. The target temperature should be between 16 and 31°C.
External air leaks – Close all doors and windows during cooling. Any influx of warm air from outside drastically reduces efficiency, especially in high heat.

Important operating points: Once the target temperature is reached, the compressor automatically stops to save energy – this is normal operation. The circulating air continues for ventilation. Cooling restarts if the temperature rises. After starting, the compressor takes up to 3 minutes to start.

Environmental conditions: The Aventa comfort operates between +4 °C and 40 °C. To optimize performance, park the vehicle in the shade, clean the roof regularly (a dirty roof heats up more), ventilate well before cooling to eliminate accumulated warm air, and do not use a steep incline (maximum 8%) in prolonged cooling mode.

If after these checks the performance remains insufficient, a refrigerant R407C charge fault or a compressor issue may be the cause. Contact an authorized Truma service center, as only the workshop is allowed to intervene on the sealed refrigeration circuit.

Question 4

Do I need to fill the water boiler to use only the heating on the TRUMA TIC C 6002?

Accepted Answer

No, it is not necessary to fill the boiler to use only the heating of the TRUMA TIC C 6002. According to the manufacturer's manual, the heating operates with full autonomy, with or without water in the boiler. Therefore, you can use the gas heating function without supplying water to the hot water circuit.

The boiler (12 liters) is an independent component intended solely for heating sanitary water. Its filling is not required for the operation of the heating system, which directly heats the ambient air by circulating warm air through the ducts of your caravan or motorhome.

Important for cold periods: If you do not fill the boiler, be aware that water may still accumulate in the boiler during operation or water refilling. To avoid freeze damage during winter (especially below 4°C), it is imperative to completely empty the boiler by pressing the "empty" control button (n) on the safety/vent valve. This draining should be done regularly if you are not using the hot water function.

In summary, you have the freedom to use gas heating exclusively without filling the boiler, which simplifies your use in winter. However, make sure to keep the boiler empty or protected against freezing to avoid any damage to the device.
