Purge Megane Refrigeration System 1.9 dt year 99

Hello!!
I would like to know if someone can help me and explain how the refrigeration circuit is purged, I have tried several times and I can't do it correctly.

The first thing I do is remove the expansion vessel plug and remove the screw from the thermostatic box, antifreeze filling through the expansion vessel until it comes out to the jet through the hole of the thermostatic box, donkey I put the screw of the thermostatic and filling the maximum the expansion To the thermostat several times and the biggest problem is that there are times that I do not have liquid in the expansion vessel and other times it is up to the expansion vessel, what do I do badly? Or what is the solution?
Thanks in advance and greetings

Thanks for the help, I'm going to try so if it works for me since it has me head.

Estimated Carlos when I have to purge a megane I always do it with the cold engine, I purge it through the the thermostatic box plug until the vessel level of expansion stops out then completely completely than the same that regulates the pressure of the water circuit. As the name of the deposit says, it is an expansion vessel where the flutua water level according to the operation pressure, before the thermostat opens the water or refrigerant liquid tends to rise level because the pressure increases up to 1 bar or 1kg then when it opens the low liquid. The extent control is done with the engine in cold.

Hello: I have problems with my megane 1.9 DTI Model 1999. Yesterday the cooling circuit disarms to clean it, with the radiator too and take out all the chips. I put together again, fill the refrigerant. He walked perfect. The next day when I am going to start it, I find it with the electro who was turned on all night, how much km of the dashboard and the clutch of the compressor of the air conditioning activated (all this without being in contact) can you guide me about what the failure can be?
