You kept a vacume until you added freon, right?1 can of freon will bring
the vacum up to about 10psi. Then start the moter and the low side will be
even less than that.Should be able to add more. When you get to the third
can , it can be very slow. Put the can in a bucket of very warm TAP  WATER
while charging . This will jet propelle the freon into your system.
