Hello, send me a photo of your gauge hoses fit to the unit, that also shows the valves at that location... so far it sounds like you either have the valves closed, or that you did not evacuate the system properly (using a vacuum pump)

Use the paper clip icon at the right end of the tool bar or then 'attach files' link to the left of your send button to attach 3 or 4 pictures of those connections and valves.

Tell me if you used a vacuum pump or not.

We can go from there,
