    why do you need to charge it. geo units come charged and all you do is hook up the water

    weight the charge and add a few extra ounces to compensate for the refrigerant trapped in your hoses, those units are very anal about their charge, every time you hook your gauges to one of them,fill you hoses with refrigerant before you do it.
