To put freon in an AC unit, you need to first locate the service valve on the unit. Then, attach a charging hose to the valve and connect it to a freon tank. Open the valve on the tank to allow freon to flow into the AC unit. Be sure to follow safety guidelines and regulations when handling freon.
Excessive freon may cause the compressor to"slug" (Seize)
Connect a freon gauge and the freon can to the low side ac port. With the ac running on high and the engine running, open the freon. Let it flow until the gauge shows that the system is full.
you need to put the freon in the low side, should be the smallest cap on the ac system
It takes R 134-a freon.
With the Freon and gauge connected to the low side ac port, start the engine. Turn ac on high, and add Freon till the gauge shows full.
Connect a freon gauge and freon can to the low side ac port. Start the engine and turn the ac on high. Open the valve to allow the freon to flow until the gauge reads full.
Using a gauge and the proper type of freon, connect to the low side ac port. Start the engine and turn the ac on high. Allow freon to flow to show a full reading on the gauge.
The freon has to be removed and the pressure released from the ac system. Then the valve can be removed and replaced. The system will need to have a vacuum pulled and freon put in again.
To put freon in an AC system, you need to first locate the service valves on the unit. Then, connect a hose from a freon tank to the low-pressure service valve. Open the valve on the tank to allow freon to flow into the system. Monitor the pressure gauge to ensure the correct amount of freon is added. Close the valve and disconnect the hose once the process is complete.
Connect a freon tank an gauge to the Astros low side ac port. Start the engine and open the ac to high. Open the freon tank and fill the system till the gauge shows full.
