You must have an injector tool to install this item. If you need an injector tool, we do have them available on this site. Look for #5055, #5060 or #5130.
If there is moisture in the system, you need to pull a vacuum or you can use the Enviro-Safe Prodry 8 oz concentrate.
The reason for the vacuum or the use of Enviro-Safe Prodry 8 oz concentrate is that it will eliminate moisture in the system. Moisture causes corrosion and nobody wants that in their system!
If the system will operate for at least 24 hours, Proseal 8 oz concentrate and Prodry 8 oz concentrate may seal the leak.
If using the Enviro-Safe Prodry 8 oz concentrate with the Proseal 8 oz concentrate, it is not necessary to pull a vacuum.
