Step-by-Step Installation:
- Preparation: Turn off the water supply to your toilet and flush to empty the cistern. Remove the old flush mechanism. Clean the inside of the cistern thoroughly.
- Install the New Mechanism: Place the Neezra universal flush mechanism into the cistern. Ensure the base seal is correctly positioned to create a watertight connection with the toilet bowl. Secure the mechanism according to your toilet's design (usually by tightening a nut from underneath the cistern).
- Connect and Test: Reconnect the water supply line to the fill valve (not included with this flush mechanism). Install the dual flush button onto the cistern lid, ensuring it aligns with the mechanism. Turn on the water supply slowly and check for any leaks. Perform several test flushes to ensure proper operation of both small and large flush options.

4. Operating Instructions
The Neezra Universal WC Flush Mechanism features a dual-flush system designed to conserve water. This system provides two flushing options:
- Small Flush (Half Flush): Press the smaller button on the dual flush actuator. This option releases a reduced volume of water, ideal for liquid waste, significantly saving water with each use.
- Large Flush (Full Flush): Press the larger button on the dual flush actuator. This option releases the full volume of water for solid waste, ensuring effective and powerful evacuation.
Always ensure the cistern has refilled completely before attempting another flush to ensure optimal performance.

5. Care and Maintenance
The Neezra flush mechanism is built with high-quality materials for a durability of 15 years. Regular, simple maintenance can further extend its lifespan and ensure continued optimal performance:
- Regular Cleaning: Periodically clean the inside of the cistern and the flush mechanism components to prevent mineral buildup and ensure smooth operation. Use non-abrasive cleaners.
- Seal Inspection: Inspect the foam seal and flush seal annually for any signs of wear or damage. Replace them if necessary using the provided replacement kit to maintain a perfect seal and prevent leaks.
- Component Check: Ensure all moving parts, especially the flush button and internal levers, operate smoothly. The product features galvanized stainless steel screws and a high-quality button to resist corrosion and wear.
