question about osmolator

[220reef]

What is the voltage setting suppose to be on the transformer for the osmolator. I have had my tank down for a while and am in the process of setting back up and the switch is all the way to the left and I know this is wrong and I can't find my instructions. Your help would be greatly appreciated.

9V is recommended but 12V will work too. If you have the older 3150 I would use 12V as when the components get old they need more power. On a 3155 I would use 9V unless you have the Calcium Dispenser and need more power.
