Before installing, use a mixing valve with the NF standard that guarantees the quality of the product, its flow rate, its finish, its sealing system and its resistance to wear .
The mixing valve is usually delivered as a kit including all connecting accessories.

A set of flat keys.
A game of screwdriver.
Protective goggles (optional)
A cutter (optional)
A mixer tap (with or without hand shower).
Two olive fittings for cold and warm water (normally included in the kit)
A Teflon roll or joint paste .

The threaded rod : Locate the threaded rod and its fixing nut, which will be used to hold the mixing valve in place. Secure the threaded rod next to the hoses in the space. Secure it first manually and then with a suitable screwdriver.
Base gasket : Insert the gasket into the space under the mixer tap. This seal will prevent water infiltration.

Check that the mixing valve is correctly positioned , place the bracket on the protective shim and then screw the fixing nut with a pipe wrench. Connect the water supply hoses. Connect the water supply to the mixer
