Safety Instructions
Repairs may only be carried out by an expert! To avoid transportation damage, the device may only be sent to the Truma Service Centre if agreed beforehand.
The power supply must be disconnected from the mains (all poles) before opening the housing.
The device fuses and connection cables must only be replaced by experts. The 230 V, T 6.3 A H (slow) device fuse can be found on the electronic control unit in the device and must always be replaced with an identical fuse.
Guarantee claims, warranty claims, and acceptance of liability will be ruled out in the event of:
- Changes to the device (including accessories).
- Failure to use original Truma parts as replacement parts and accessories.
- Failure to follow the installation and operating instructions.
Such changes or non-compliance also invalidate the device operating permit, which in many countries also denotes expiry of the vehicle operating permit.
The refrigerant circuit contains R 407C refrigerant and must only be opened in the factory.
The air inlets / outlets at the external unit and the air distributor must not be obstructed under any circumstances. This is essential in order to ensure that your device operates correctly.
To avoid damage to the compressor, do not drive on uphill or downhill slopes with an incline of more than 8% when the device is operated while driving (e.g., with generator or voltage converter).
Do not operate the device in cooling mode for long periods with the vehicle at an angle, as condensation may not be able to run away and may penetrate the vehicle if circumstances are unfavourable.
For problem-free operation and to avoid damage, the supply voltage must always come from a source with a sine wave curve (e.g., voltage converter, generator) and without voltage spikes.
When cleaning the vehicle, ensure no water gets into the device when spraying with a high-pressure cleaner (do not spray directly into the device openings).
Hot cleaners and steam cleaners must not be used.
Condensation traps must always be unobstructed.
Notes on Using Air Conditioning Systems
The air conditioning system is designed for a power consumption of up to 4.2 A. Check if the campsite has adequate fuse protection (min. 6 A) before starting.
Park the vehicle in the shade if possible.
Darkening with blinds reduces heat insolation.
Clean your roof at regular intervals; dirty roofs heat up more than clean roofs.
Ventilate your vehicle well before starting the equipment to remove accumulated warm air.
For a healthy room climate, keep the difference between inside and outside temperatures moderate. The recirculated air is cleaned and dried during operation. A pleasant room climate is produced by drying the moist air, even with small temperature differences.
Keep all doors and windows closed in cooling mode to prevent condensation buildup at the air distributor.
For faster cooling or heating:
- Set fan level to high.
- Set front / rear air distribution to the centre position.
- Set floor / ceiling air distribution to the ceiling.
