Truma Aventa Eco Air Conditioner System
The Truma Aventa Eco air conditioning system provides efficient
cooling, dehumidification, and air circulation for enhanced comfort
in your MDC XT12HR OGE trailer. The system operates via the
Truma CP Plus digital control panel and remote control, offering
multiple modes and adjustable fan speeds.
Safety Information
• Always switch OFF the A/C isolator switch and disconnect power before performing maintenance.
• Do not use the air conditioner in areas with flammable gases or liquids to avoid fire hazards.
• Never clean the unit with a pressure washer, steam cleaner, or hot water—use only a soft cloth with mild detergent.
• Ensure the air inlets and outlets are unobstructed to prevent overheating.
• Do not operate the Aventa Eco in cooling mode when the trailer is parked on a steep incline (above 8% or 4.5° tilt) to prevent
improper condensation drainage.
• Keep condensation drains clear to avoid water damage inside the vehicle.
• Use only AC power or the factory-installed Renogy power system when off-grid—unregulated power sources may damage
the unit.
