Introduction:

This document is designed for customer service and technical staff to assist with inquiries, troubleshooting, and guidance on the Thetford SC250/C260 waste-holding tank mechanism. It provides detailed instructions for the replacement of the holding tank mechanism or its components.

Important Note:

For operations involving the C250 model and the replacement of the Holding Tank or the Holding Tank Mechanism (or the plate of the Holding Tank Mechanism), it is highly recommended to also replace the bowl retainer bracket to prevent leakage.

Tools Required:

No specific tools are listed for this operation, but standard plumbing tools may be required for the removal and installation of the tank mechanism.

Replacement Instructions:

• Identifying the Mechanism:

  • Upon inspection of the top of the tank, locate the sliding cover.
  • Notice an arrow on the disc, which points towards a solid dot on the main body of the toilet.

• Removing the Mechanism:

  • Remove the sliding cover by lifting it off the mechanism.
  • Re-insert the sliding cover from the opposite end of its original position.
  • Use the sliding cover as a lever to rotate the entire mechanism counterclockwise (anti-clockwise) until the arrow aligns with the second dot on the main body.
  • At this point, the complete disc and mechanism should be free to remove.

• Installing the New Mechanism:

  • To install the new mechanism, reverse the removal process.
  • Ensure the sliding cover is correctly positioned to allow the mechanism to lock into place when rotated clockwise.

Troubleshooting Tips:

• Leakage Issues:

  If experiencing leakage after replacing the holding tank mechanism, ensure that the bowl retainer bracket has also been replaced, especially for the C250 model. Check all seals and connections for proper fit.

• Mechanism Does Not Fit:

  Ensure that the mechanism is aligned correctly with the internal components of the tank. The arrow and dots on the mechanism and tank body are guides for correct alignment.
