Service Port HVAC: Description and Operation
Fig 4 A/C Service Ports
The refrigerant system service ports are used to charge,recover/recycle, evacuate, and test the air conditioning refrigerant system. Unique service port
fitting sizes are used on the R-134a system, to ensure that the refrigerant system is not accidentally contaminated by the use of the wrong refrigerant
(R-12), or refrigerant system service equipment.
After servicing the refrigerant system, always reinstall the service port caps.
