Using a set of a/c gauges put the blue hose on the low side (suction side) and the red hose on the high side (discharge side) and make sure that there is no freon in the system and if you have freon in the system then you will have to go to an automotive a/c shop and have them reclaim it for you..
Put the yellow hose on your vacuum pump and let it run for about 1 hour and then let it sit for 1 hour so that you can see if it will at least hold the vacuum pulled.
If so then let it run for an additional hour and then start the recharging process remembering to keep the low side readings between 30 to 40psi and the high side between 200 to 250psi depending on the outside temperature…………….
