Identify
Confirm your Thomas Dudley frame series — Miniflo 42mm plates only fit specific in-wall carriers. Look on the inspection window for the frame's date-stamp and part number.
Remove the old plate
Pull the Thomas Dudley Miniflo 42mm plate away from the wall (magnetic or clip-on). Disconnect the two flush levers or pneumatic tubes from the top of the cistern.
Fit the new plate
Adjust the Thomas Dudley Miniflo 42mm lever rods to length. Reconnect, refit the plate. Test full and reduced flush volumes (6 L / 3 L standard UK).
