Fitting the Cistern to the Toilet Pan
With the flush valve and inlet valve fitted and adjusted the cistern tank can be fitted to the pan.
Fit the gasket around the flush valve outlet on the underside of the cistern.
When fitting the cistern to the pan take care to ensure the gasket is properly aligned in the gasket location. Failing to do so could result in leakage.

MAKING PLUMBING CONNECTIONS
Connect the soil pipe and ensure it is adequately sealed around the toilet pan outlet to prevent leakage, using a suitable compound such as
Plumber’s Mait.
The inlet valve has a threaded connector. It is recommended that this thread is wrapped in PTFE tape before connecting the water supply. Do not overtighten the supply to the inlet valve as this could damage the inlet valve causing leakage.
After connecting the water supply to the inlet valve check that the inlet valve components do not touch the internal walls of the cistern and the float can move freely up and down.
Check all connections are secure and a soil pipe is fitted before testing the flush.
