Hi, will the 40-189 automatic door closer gently close an internal house door weighing approx 13kg/kilograms or will it slam the door shut even at its lowest tension setting?

Thanks for posting. The 40-189 door closer can support storm doors that weigh up to 150 lbs. (or 68kg). With that in mind, I think a 13kg. door would be fine.
