Always charge by specs. We are so far from the retrofit pressure charts at this point, IMO.

I asked the other day if it was a preset thermostat. The rotary dial, when turned completely clockwise, will not cycle.

These systems typically require a specific amount of refrigerant. Check the instructions or contact them for the current capacity. Does this system have a preset thermostat? Is the probe inserted correctly to the proper depth?

Sorry for the late response. If you can build a #12 suction line. That would be best overall. In many cases, they use a #10 due to the availability of fittings.

Thank you for the support.

Cheap Hose.
It looks like the extruder failed the last process to me.

What are you apologizing for?
Best to make a custom hose in situations like this.

The way I read your post. You ended up charging the system back up without it in a vacuum? If that is the case, the system needs to be charged into a vacuum.

Amen.
