Instructions for use:

Step 1: Turn the a/c system on, and verify the unit is running. Connect ProSeal Mini Inject to the low side service port of the system. (This is generally the large line.) 

Step 2: Connect the manifold refrigerant hose to the refrigerant supply tank. Verify the manifold high & low side valves on the manifold are closed before proceeding. Purge the air from the low side.

Step 3: Open low side valve, watch for the tube to clear. (This will ONLY take a few seconds!) Turn off low side manifold valve as soon as the tube is clear. Turn off refrigerant gas. Verify the system is charged to manufacturer’s specifications. Disconnect low side hose from ProSeal Mini Inject. Install service port cap. Run the a/c unit at least one hour after installing ProSeal Mini Inject.

Note: Do Not use Enviro-Safe ProSeal Mini Inject in any manner it was not designed!
