npc spawn on server startup


I tried to make a simple NPC wich executes a code if you press E on it.
After I failed with my own code I downloadet this:

It works perfectly,
but I want to make it spawn automaticly on server startup.
And spawn on a PRESET POSITION.

I tried to add
ENT:SetPos(Vector(837, 434, 95))
to the code, or
function ENT:Initialize()

but it spawns always on my aim position.
I am a LUA beginner, could anyone please help me with my issue ?

Thank you for all your help.
