Installation Instruction:

1	Before Installing the valves, clean and remove any objests from the pipes
2	Ensure both connection pipes either side of valves and aligned
3	Ensure that two sections of the pipe match, and the valves until will not accept any
	gaps, any distroy in the pipes may affect the tighting of the connection, The work
	of the vales and can even casue a rupture. To be sure, place the kit in position to
	ensure the assembling will work
4	Before starting the fittings, ensure the threads and tappings are clean
5	If secton of pipes have not their final support in that place, They can be temporatily
	fixed, In order to avoid unnecessary strain on the valves
6	The theoretical lenghts gived by ISO7/1 for the tapping are typically longer than
	required, The length of the thread should be limited, and check that the end of tube
	does not press right up to the head of the thread
7	For the sealing assembly valves pipes, it is essential to use products that are
