Fitting the Cistern to the Toilet Pan
Installing Push Button
With the flush valve and inlet valve fitted and adjusted the cistern
tank can be fitted to the pan.
Fit the push button to the cistern lid using the plastic fixing nut.
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.
Ensure the pins make contact with the flush buttons on the flush valve. To
adjust the length of the rods turn the nut clockwise and anti-clockwise.

MAKING PLUMBING CONNECTIONS
Connect a new WC Pan waste connector 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.
Do NOT use silicone around gaskets or rubber seals as this will impair
sealing of the rubber components. 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.
Care
DO NOT introduce caustic chemical substances (e.g. containing chlorine
compounds or similar). These can damage the valve components and
cause failure.
Water Level Adjustments
It is important that there is a minimum air gap between the outlet of the fill
valve and the top of the overflow of 30mm.
Also the water level in the tank must be between 25-32mm below the
overflow tube on the flush valve.
Check all connections are secure and a soil pipe is fitted before testing the
flush.
