4. Setup and Installation
4.1 Tools Required (Not Included)
- Adjustable wrench
- Screwdriver (Phillips or flathead, depending on screws)
- Drill (if new mounting holes are required)
- Level
- Pencil
- Sealant tape (PTFE tape)
4.2 Installation Steps
- Prepare the Area: Turn off the main water supply to the toilet. Flush the toilet to empty the existing tank. Disconnect and remove the old cistern if applicable. Clean the mounting surface.
- Mount the Cistern: Position the new Cornat Pontos cistern on the toilet bowl or wall mounting points. Use the provided mounting hardware to secure it firmly. Ensure the cistern is level before tightening all fasteners.
- Connect Water Supply: Connect the water supply line to the fill valve inlet on the cistern. Use sealant tape on threaded connections to ensure a watertight seal. Hand-tighten, then use a wrench for a final quarter-turn. Do not overtighten.
- Connect to Toilet Bowl (if applicable): If the cistern mounts directly to the toilet bowl, ensure the rubber gasket is correctly seated between the cistern and the bowl, and tighten the bolts evenly to prevent leaks.
- Adjust Fill Valve: Once water supply is reconnected and turned on, the cistern will begin to fill. Adjust the fill valve float mechanism to set the desired water level. The water level should be below the overflow pipe.
- Adjust Flush Volume: The Cornat Pontos cistern features adjustable dual-flush volumes. Refer to the internal mechanism for specific adjustment points. Typically, a small adjustment lever or screw allows switching between 6/9 litre and 3/4.5 litre flush options. Test both flush options to ensure proper operation.
- Leak Check: After installation, turn on the main water supply slowly and check all connections for leaks. Tighten any leaking connections gently.
5. Operating Instructions
The Cornat Pontos SPK1200 cistern is equipped with a 2-volume dual-flush system, allowing you to choose between a full flush and a reduced flush for water conservation.
- Full Flush (6 or 9 litres): Press and hold the larger flush button (or push the lever fully down) for a complete flush. This is typically used for solid waste. The exact volume (6 or 9 litres) depends on the internal adjustment made during installation.
- Reduced Flush (3 or 4.5 litres): Press the smaller flush button (or push the lever partially down and release) for a water-saving flush. This is ideal for liquid waste. The exact volume (3 or 4.5 litres) depends on the internal adjustment made during installation.
Ensure the flush buttons or lever operate smoothly and return to their original position after each flush.
6. Maintenance
6.1 Cleaning
- Clean the exterior of the cistern with a soft cloth and mild, non-abrasive cleaning solution.
- Do not use harsh chemicals, abrasive pads, or solvents, as these can damage the surface finish.
- For internal cleaning, turn off the water supply, flush the cistern to empty it, and then wipe down accessible surfaces.
6.2 Regular Checks
- Periodically check for leaks around the base of the cistern and all water connections.
- Ensure the fill valve is operating correctly and the water level is maintained below the overflow pipe.
- Inspect the flush mechanism for any signs of wear or obstruction.
