Heat Controller ductless mini-split

[mark7]

I have a problem that I cant figure.The suction line is in a vacuum as soon as the unit starts.I thought it must be low on refrigerant so I leak checked unit.Could not find anything,so I recovered the charge,weighed it and it was ok.I weighed in the correct amount again,and the suction goes into a vacuum again.(R-22 unit by the way)The nameplate says 11.7 amps and it draws only 5+The lineset isnt too long.It is a 110 volt unit.All the fans work.It is a Heat Controller model A-HMC12AS.Any thoughts or suggestions out there?I would really appreciate it.

Just one: Call a professional. No offense intended. But tinknocker's answer could have been provided by a recent trade school graduate, which means you should have been able to provide it as well.

Or,open the liquid service valve.

(but dont mention this to Irascible...)

I should of mentioned I checked the service valves.They are open.There isnt a expansion valve,it is a fixed orifice.Any other suggestions?

Did you forget to take the rubber plug out of the lines set before making connections. I have seen this before.
