Recharging AC Through HIGH Pressure Port?

Recharging AC Through HIGH Pressure Port?
I was attempting to recharge my 2002 Acura RL with R134a after changing the compressor using AC gauges and a can of refrigerant hooked up through the yellow hose. I noticed that next to no refrigerant came out of the can (I had it on a scale) but the pressure went up to 60 on the Low Port. I didn't open the high port to charge. The compressor didn't kick on and no more refrigerant came out of my can.
I then rechecked the Service Instructions I have an it says this:
Does this mean I should have tried adding refrigerant to the HIGH pressure port? Isn't that normally a no-no?
Any help is appreciated
I then rechecked the Service Instructions I have an it says this:
2. Open the high-pressure valve to charge the system
to the specified capacity, then close the supply
valve, and remove the charging system couplers.

Did you pull a vacuum after you changed the compressor?You can only fill thru the high port with the engine off.This is done at the factory and can be done with a reclaimer or even with a set of gauges.But once the compressor is running the high side valve should be closed as this area now has high pressure.The low side is also the suction side.Refrigerent can be added here till you have proper pressures or a clear sight glass o n the earlier models.
