4. Setup and Installation
Follow these steps for proper installation of your CORNAT SPK1115 Triton Cistern:
- Prepare the Installation Area: Ensure the wall surface is clean, dry, and structurally sound. Mark the desired mounting height for the cistern above the toilet bowl.
- Mount the Cistern: Using the provided mounting accessories, securely attach the cistern to the wall. Ensure it is level before tightening all fasteners.
- Connect the Water Supply: The cistern offers a 3-side connection option (left, right, or rear). If using a side connection, carefully create the necessary opening in the cistern body as indicated in the installation diagrams. Connect the chrome-plated corner valve to the water supply line. Then, connect the chrome-plated copper pipe (Ø 10 mm) from the corner valve to the cistern's fill valve inlet. Ensure all connections are sealed properly with the provided washers and tighten securely.
- Connect the Flush Pipe: Attach the flush pipe bend (Ø 50 x 44 mm; 210 x 200 mm) to the cistern's outlet. Connect the other end of the flush pipe to the toilet bowl's inlet using the flush pipe connector and ensure a tight seal.
- Check for Leaks: Slowly turn on the main water supply and allow the cistern to fill. Carefully inspect all connections for any signs of leakage. Tighten connections as needed.
- Adjust Flush Volume (Optional): The cistern supports adjustable flush volumes (6-9 liters for full flush, 3-4.5 liters for reduced flush). Refer to the internal mechanism instructions for specific adjustment procedures, typically involving a float or lever setting.
5. Operating Instructions
The CORNAT SPK1115 Triton Cistern features a dual-flush mechanism for water conservation:
- Reduced Flush (3-4.5 liters): Press the smaller button on the top of the cistern lid for a reduced water flush, suitable for liquid waste.
- Full Flush (6-9 liters): Press the larger button on the top of the cistern lid for a full water flush, suitable for solid waste.
The fill valve is designed for quiet operation (noise class 1) during refilling.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your cistern:
- Cleaning: Clean the exterior of the cistern with a soft cloth and mild, non-abrasive cleaning solution. Avoid harsh chemicals that can damage the plastic finish.
- Internal Inspection: Periodically remove the cistern lid and inspect the internal components (fill valve, flush mechanism, seals) for wear, debris, or mineral buildup.
- Fill Valve Maintenance: If the cistern fills slowly or makes excessive noise, the fill valve may need cleaning. Shut off the water supply, remove the fill valve, and rinse any debris from its components.
- Flush Valve Seal: If the toilet continuously runs, the flush valve seal may be worn or obstructed. Shut off the water, drain the cistern, and inspect or replace the seal as necessary.
- Leak Checks: Regularly check all water connections for drips or leaks. Tighten fittings or replace seals if leaks are detected.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cistern not filling | Water supply off; clogged fill valve; faulty fill valve | Ensure water supply is on; clean fill valve; replace fill valve |
| Cistern continuously runs | Worn or obstructed flush valve seal; fill valve set too high; faulty fill valve | Inspect/replace flush valve seal; adjust fill valve float; replace fill valve |
| Weak or incomplete flush | Low water level; obstructed flush pipe; faulty flush mechanism | Adjust water level; clear flush pipe; inspect/replace flush mechanism |
| Loud noise during filling | High water pressure; fill valve issue | Install a pressure reducer (if pressure is too high); inspect/replace fill valve |
