Does anyone have a similar, quite old Retarder/Proofer for SinMag? I just got hld of it second hand and it does not have a manual. Most of It I have figured out. Over on the left of the picture there are two rotating controls to adjust the hydration. One seems to control how often the plumbed in water is sprayed in and the other is I think is for the length of the time the water should be sprayed. Both I assume are in seconds.
Anyone have an idea of how these should be used?
Thank you for reading.
