How to safely handling and replace a Pressure switch in an air conditioning system on Nissan 240sx?

The compressed refrigerant in the air conditioning system expands into the atmosphere at a temperature of -2°F or lower, which can freeze any surface it contacts, including eyes, and decomposes into a poisonous gas in the presence of a flame. Begin by discharging the air conditioning system. Next, disconnect the electrical connector from the switch. Use a flare nut and backup wrench to loosen the air conditioning pipe fittings and remove the switch/line assembly, or just the switch from the receiver dryer assembly, depending on the application. Installation follows the reverse order of removal, ensuring that new O-rings are used. Finally, evacuate, recharge, and conduct a leak test.
