put the tap on pull the charge do a vac test(empty the evap barrel prior to the vac so no water gets sucked in)isolated the water lines in and out...after you have a good vac open the barrel drain and see if you have any vac within the barrel.swet on shradder/copper on the suction and discharge and revac this will give you a good working access to the system to further test.
