Yellow Jacket Refrigerant Recovery Step-by-Step

According to the U.S. Environmental Protection Agency's Clean Air Act, it is illegal for anyone who works with refrigerants to dispose of them in a way that allows them to enter the environment. Therefore, technicians use refrigerant recovery methods when disposing of refrigeration or air conditioning devices. There are three different refrigerant recovery methods. While the vapor recovery method is most commonly used, technicians also employ the push pull method and the liquid recovery method. All three methods can be used with Yellow Jacket refrigerant recovery products.

Vapor Recovery Method

Filter dryers should always be used with a refrigerant recovery unit.

Step 1

Lift the Yellow Jacket recovery cylinder onto the scale.

Step 2

Connect a hose to the HVAC system's service port. Connect the alternate end of the same hose to the manifold set's center port.

Step 3

Connect a separate hose to the manifold set's lower side. Connect the alternate end of this hose to the Yellow Jacket recovery equipment's suction area.

Step 4

Connect the last hose from the vapor port on the tank to the manifold set's high gauge.

Step 5

Close the manifold set's valves. Open the Yellow Jacket recovery cylinder's liquid and vapor valves.

Step 6

Start the Yellow Jacket recovery system. The unit will begin to recover the refrigerant. Once recovery is complete close all valves.

Step 7

Begin the purge cycle or disconnect the unit from the HVAC system.

Push Pull Recovery Method

Step 1

Connect a hose from the vapor port of the tank to the manifold set's port.

Step 2

Connect a hose from the manifold set's low side to the Yellow Jacket recovery unit's suction side

Step 3

Connect a hose from the Yellow Jacket recovery unit's discharge side to the service port's low side.

Step 4

Connect a hose from the service port's high side to the tank's liquid valve.

Step 5

Lift the tank onto the scale and open the Yellow Jacket recovery cylinder's valves.

Step 6

Start the machine and open the manifold set's low side valve.

Step 7

Watch the scale. Once the scale shows the tank's weight has stopped increasing, switch the device to vapor recovery.

Liquid Recovery Method

Step 1

Lift the Yellow Jacket recovery cylinder onto the scale.

Step 2

Connect a hose to the HVAC system's service port. Connect the alternate end of the same hose to the manifold set's center port.

Step 3

Connect a hose from the Yellow Jacket recovery unit's discharge side to the service port's high side.

Step 4

Connect the last hose from the vapor port on the tank to the manifold set's high gauge.

Step 5

Close the manifold set's valves. Open the Yellow Jacket recovery cylinder's liquid and vapor valves.

Step 6

Start the Yellow Jacket recovery system. The unit will begin to recover the refrigerant. Once recovery is complete, close all valves.

Step 7

Begin the purge cycle or disconnect the unit from the HVAC system.
