  • 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.
