first you open the high side so the low side can go into a vacuum and purge out the air. next you add a small charge and close the system and let it circulate. next open the high side to dump the charge and let the high side sit open for a minute to make sure everything is purged. close the high side and add the factory charge to the low side as a gas, not a liquid.
