You add refrigerant at the low pressure port but you do not add Freon. You add R134/134a. If you are having to add refrigerant then you have a leak that needs to be repaired first.
How do I put freon in a 2002 Cadillac deville
Take it to the a auot shop. you can not add freon
The high/low pressure lines have valves (1 each) like a tire. You plug a can into each side to recharge. the can will have the fitting and a guage.
It contains no Freon. It contains R134a refrigerant and you add it to the low pressure port which is the larger pipe.
I had an additive put in my Lincoln ls. I bought the adapter needed to add freon. It was located on driver side in front of tire.
A General Electric dehumidifier uses a sealed unit that does not have any way for you to add Freon to the unit. If you want to add Freon, you have to first install saddle valves to the dehumidifier.
There is one valve that is used to add refrigrant. But you had better not add Freon. Freon is R12 and your vehicle's A/C system does not have Freon (R12) as a refrigrant. More than likely it uses R134a.

Connect guage & 134a freon to low pressure on the evaporator add 1lb at a time
on the low side only
You add the refrigerant through the low side service port.
