FINAL INSTALLATION CHECK LIST:
Check all moving components operate freely and the inlet valve shuts off correctly.
If overflowing or poor flushing subsequently occurs, check that the float and arm move freely up and down and that the water level is correct.
Check all joints are tightened correctly.
Check carefully for leaks.
Hold the inlet valve float down, causing the cistern to internally overflow. Ensure the overflow pipe is capable of discharging all incoming water
without the cistern overflowing. If water overflows the cistern make sure that the flow restrictor is fitted. If overflowing persists contact:
WARNING: No sealing compound, paste, flux or solvent to be used in contact with plastic or rubber surfaces to avoid damage. Rubber washers
or ‘O’ rings should provide an adequate seal. PTFE tape may be used on threads. Do not over tighten plastic nuts.
No chemical block or additive is to be used in this cistern.
