Introduction
The COMAP Trombe AR 2001 is a hydropneumatic toilet flush mechanism designed for efficient and reliable operation in WCs and toilets. This mechanism utilizes compressed air from the water network to provide a powerful flush. It includes a stopcock and a non-return valve for optimal performance and safety.
Key benefits of the Trombe AR 2001 include:
- Space-saving design: Installs effectively in confined spaces.
- Flexible installation: Allows for the toilet seat to be installed flush against the wall.
- Tamper-proof: The mechanism is designed without external access, enhancing durability and security.
- Water saving: Engineered for water efficiency with each flush.
- Powerful flush: Delivers a strong flush due to its pressure-based system.

Setup and Installation
The Trombe AR 2001 is designed for straightforward installation, even in compact areas. Ensure that the installation environment meets the following requirements:
- Operating Pressure: The water network pressure must be between 3 and 6 bar.
- Capacity: The mechanism is designed for a capacity of 11.5 to 12 liters.
The compact design allows for flexible placement, including installations where the toilet seat can be positioned directly against the wall, optimizing space utilization in bathrooms or WCs.

Operating Instructions
The Trombe AR 2001 operates using a hydropneumatic system. When the flush handle is activated, compressed air from the water supply, located in the upper part of the mechanism, forces water into the toilet bowl, initiating the flush.
- Initiating a Flush: To flush, firmly press and hold the flush handle.
- Measured Flow Mechanism: The mechanism features a "measured flow" system. The water flow will stop automatically as soon as the flush handle is released. This allows for partial flushes and water conservation.
- Adjusting Flow: The flush flow rate can be adjusted to suit the specific water network pressure and the model of the toilet bowl. Refer to the installation guide or consult a professional for detailed adjustment procedures.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Trombe AR 2001 flush mechanism. Due to its tamper-proof design, internal access is limited, making professional servicing advisable for complex issues.
- Cleaning: Periodically clean external components with a mild, non-abrasive cleaner. Avoid harsh chemicals that could damage the finish or internal seals.
- Leak Detection: Monitor for any continuous water flow into the toilet bowl, which may indicate a seal issue.
- Repair Kits: COMAP offers specific repair kits for the Trombe AR 2001. If components like the handle spring require replacement, consider using official parts.
