Draining a Culligan Mark 89 Water conditioner

We live in Northern MN and would like to winterize our home for the winter. How do we drain the water out of our Culligan Mark 89 Water Softener system so it does not freeze? The owners manual does not address it.

A Mark 89 is an old model, so what was done in years past to prevent freezing?

That's what should be done now because you will have a difficult time pouring the water out of a softener; there is no drain on the bottom. And resin can not be allowed to dry out, that will ruin it. And you don't want resin packed up in the control valve.

A good idea is to disconnect it, pour some water out of it, just a gallon or two and take it where there is heat; like at home. Don't lay it down more than a 45* angle. You want the resin covered with water and not to get it up into the control.

You could use Recreational Vehicle antifreeze (not automotive type, it has to be for potable water use) IF you get the right amount into the tank.
