Setup and Installation

Safety Precautions:

  • Ensure the water supply to the toilet is turned off before beginning installation.
  • Drain the cistern completely before removing any components.
  • Wear appropriate personal protective equipment (PPE) if necessary, such as gloves.

Tools Required:

  • Adjustable spanner or wrench
  • Screwdriver (if needed for existing components)
  • Towels or sponges for water absorption

Installation Steps:

  1. Step 1: Remove Existing Components

    Carefully disconnect the water supply pipe from the cistern. Unscrew and remove any existing bolts securing the cistern to the toilet pan. Lift the cistern away from the pan. Remove the old accelerator kit and flush cone from the cistern.

  2. Step 2: Install New Accelerator Kit

    Position the new internal rubber flush cone into the cistern outlet. Place the Nocturne Accelerator Kit over the flush cone, ensuring it is seated correctly and aligned with the cistern's internal structure.

  3. Step 3: Reattach Cistern and Back Plate Bolts

    Carefully lower the cistern back onto the toilet pan, aligning the outlet with the pan inlet. Insert the new back plate bolts through the designated holes in the cistern and pan. Secure the bolts with the provided washers and nuts, tightening them evenly to prevent stress on the ceramic. Do not overtighten.

  4. Step 4: Reconnect Water Supply and Test

    Reconnect the water supply pipe to the cistern inlet. Slowly turn on the water supply and allow the cistern to fill. Check for any leaks around the connections and the base of the cistern. Perform several test flushes to ensure the accelerator kit operates correctly and the flush is efficient.

Operation

The Twyford Nocturne Accelerator Kit is designed to enhance the flushing performance of your low-level close-coupled toilet. Once installed, the flush mechanism operates as standard. Pressing the flush button or lever activates the accelerator, providing an efficient and powerful flush by optimizing water flow from the cistern to the toilet pan.

Maintenance

To ensure the longevity and optimal performance of your Twyford Nocturne Accelerator Kit, follow these maintenance guidelines:

  • Regular Cleaning: Clean the toilet and cistern exterior regularly with mild, non-abrasive cleaners. Avoid harsh chemicals that could damage rubber components or the plastic accelerator unit.
  • Inspect for Leaks: Periodically check for any signs of water leaks around the cistern base or connections. Address any leaks promptly to prevent water waste and potential damage to your bathroom.
  • Check Flush Performance: If you notice a decrease in flush efficiency or unusual noises, inspect the internal components of the cistern. Ensure the flush cone is free from debris and the accelerator mechanism moves freely without obstruction.
  • Component Replacement: If any part of the kit becomes worn or damaged, replace it with genuine Twyford spare parts to maintain performance and compatibility.
