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.

Gasket

Insert the cistern fitting bolts arranging the components as shown in
the diagram below.

Firmly tighten the nuts and wing nuts taking care not to overtighten as
this could damage the ceramic.

MAKING PLUMBING CONNECTIONS

Connect the soil pipe and ensure it is adequately sealed around the
toilet pan outlet to prevent leakage.

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.

valve.

OPERATION

Press the small button once for a small flush (4 litres factory setting)

CARE

DO NOT introduce caustic chemical substances (e.g. containing
chlorine compounds or similar). These can damage the valve
components and cause failure.
