Installation Instructions
YOUR TOILET is just one part of a system. Correct
installation of the whole system is essential if you want the
toilet to perform properly, operate reliably and safely, and give
satisfactory length of life. The toilet is delivered assembled
for right-handed operation. If you wish, both Regular and
Compact Bowl models may be re-assembled with the pump
on the left hand side. The seat and lid is delivered boxed and
unfitted for its protection.
NB: Key numbers, e.g. ('Key 31'), are references to the
exploded view diagram on the back page.
1. Re-assembly for left hand use
If you wish to change the pump mounting from right to left
hand, do so before installing the toilet.
• Pull off the hose (key 4) that runs from the pump to the
bowl.
• Remove the 4 screws (key 31) that secure the pump
assembly to the base.
• Lift off the pump assembly and leave the base valve
gasket (key 16) on its 3 locating pegs.
