HELP with LG dual zone
Have a split system LG running R410A, my problem is that the unit when started up was pulling a vac on the suction side(no where to hook hi side gauge so i dont know whats happening there). i found that the only ***** in the system was what was added to the indoor units after install so i recovered etc.
recharged to factory specs and suction pressure shot up to 300 and wouldnt fall. i thought i overcharged so i evacuated but the system had only gas, the 4 pounds i charged seemed to dissappear.
I found the ***** by cracking the flare nut on the high side and it spewed oil/*****, meanwhile i can pull a vac on the suction side and spew ***** on the high side at the same time?
i normally work on air dryers not conditioners so if this is a really stupid problem cut me a little slack
