Hi Pegg,
We're glad to help! To fill with e-liquid, simply grip the top cap, and unscrew. You will notice that the chimney and coil will come out as one solid unit, leaving behind just the "cup"-like tank and base. Grab your favorite e-juice and fill to the MAX line designated on the outside of the tank. Please do not overfill. Now take the top piece, insert it back into the tank and screw back securely. You are ready to vape!
Best regards,
Brad
