Installation & Compatibility Notes
Cistern Model Verification: This plate is designed specifically for Schwab UP 182 cisterns. It is NOT compatible with Schwab UP 189, UP 192, UP 199, or cistern models from Geberit, Grohe, or Tece.
Actuating Rod Adjustment: Secure the mounting counter-frame squarely to the inspection tunnel. Set the threaded mechanical actuating rods so they make light contact with the valve levers without pressing down on them; setting rods under tension will hold the valve seal off its seat and cause constant weeping into the pan.
Compatible Replacement Spares
- Matching Cistern Range: Schwab / Fluidmaster UP 182 concealed cisterns
- Internal Flush Valve: Schwab UP 182 dual-flush discharge valve assembly
- Mounting Hardware: Supplied complete with backing counter-frame, threaded actuating rods, and fixing screws
