4. Setup and Installation
Follow these steps to install the Comap 3051 Cistern Adaptable Mechanism:
- Turn Off Water Supply: Locate the water shut-off valve for your toilet, usually found on the wall behind or near the toilet. Turn it clockwise until the water flow stops completely. Flush the toilet to empty the cistern.
- Remove Old Mechanism: Disconnect the flush chain or rod from the old mechanism. Unscrew any retaining nuts from the underside of the cistern that secure the old mechanism. Carefully lift and remove the old flush mechanism from the cistern. Clean any residue from the opening.
- Install New Mechanism: Insert the Comap 3051 mechanism into the opening at the bottom of the cistern. Ensure the rubber seal is correctly seated against the inside of the cistern. From the underside of the cistern, secure the mechanism with the provided retaining nut, tightening it firmly but without over-tightening to avoid cracking the ceramic.
- Connect Flush Lever/Button: Attach your existing flush lever or button to the new mechanism's operating arm. Adjust the chain or rod length to ensure proper operation without excessive slack or tension.
- Restore Water Supply: Slowly turn the water shut-off valve counter-clockwise to restore the water supply to the cistern. Allow the cistern to fill. Check for any leaks around the base of the mechanism and the water inlet connection.
- Test Operation: Flush the toilet several times to ensure the mechanism operates smoothly, the cistern fills correctly, and the flush is effective. Adjust the water level if necessary (refer to the Maintenance section).
5. Operating Instructions
The Comap 3051 mechanism operates as a standard toilet flush valve. To flush the toilet, depress the flush lever or button. This action lifts the internal seal, allowing water to flow from the cistern into the toilet bowl. Once the flush is complete, the seal will return to its closed position, and the cistern will begin to refill automatically.
6. Maintenance
- Regular Cleaning: Periodically inspect the mechanism for mineral deposits or debris. If necessary, turn off the water supply, drain the cistern, and gently clean the components with a soft brush and mild detergent. Avoid abrasive cleaners.
- Check for Leaks: Regularly check for any signs of water leakage from the cistern into the toilet bowl (a running toilet). If a leak is detected, inspect the rubber seal at the base of the mechanism for wear or obstruction.
- Adjusting Water Level: The water level in the cistern can typically be adjusted by manipulating the float mechanism. Refer to the specific design of your float for adjustment instructions. The water level should be below the overflow pipe to prevent continuous running.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet runs continuously | Flapper/seal not seating correctly; float level too high; debris under seal. | Check and clean the seal. Adjust the float arm to lower the water level. Ensure the flush chain/rod is not too tight. |
| Weak or incomplete flush | Insufficient water in cistern; flush chain/rod too loose. | Adjust the float to allow more water into the cistern. Shorten the flush chain/rod slightly. |
| No flush when lever is pressed | Flush chain/rod disconnected or broken. | Reconnect or replace the flush chain/rod. |
| Water leaking from cistern base | Mechanism not seated properly; retaining nut loose; damaged seal. | Turn off water, drain cistern, re-seat mechanism, tighten retaining nut, or replace the seal if damaged. |
