I was using a fridge compressor to evacuate it - they only go to about 26 inHG. And it stayed there, so there is no leak, or at least a leak is not the problem.

The pressure is still there this morning but it's dropped a little, I guess because of the drop in temperature in the morning. Pressure is now 70PSI -that's enough to switch on the compressor isn't it?

I just realized I may have put a little too much ES-12 in - I put in just under 3 of the 6 oz cans, which they say is the equivalent of about 18oz a can. So that's 3lb 6oz and the 240D is only supposed to have 2lb 9 oz right? So that's quite a bit over.

However, that wouldn't stop the compressor switching on, especially since I had it switched on after the first can and it never came on. Time to jump the clutch...
