Assembly

Assemble the float valve by screwing on both the valve and the float ball to the threaded rod. Tighten the lock nuts to secure the assembly.
Fit the 50/40 full thread reducer to your tank inlet.
Fit one 40/20mm reducer to the front of your 50/40mm full thread reducer on the outside of the water tank.
Fit the float valve to the other 40/20mm reducer, and fit the entire assembly to the inside of your 50/40mm reducer on the inside of the water tank.

Adjustment:

The shut-off height of the float valve can be adjusted by loosening the wingnut on the arm of the valve and angling it to the desired point.

Connection:

If you want to fill your water tank using a hose pipe, fit the 20mm male hose connector to the front of your 40/20mm reducer.
If you are connecting directly to your plumbing line, omit the use of the 20mm male hose connector and connect your plumbing line directly to the 40/20mm reducer.

Optional Hush Pipe:

If required, fit the optional hush pipe to the outlet at the bottom of the float valve.
