Can you advise me, regarding the maintenance of my water cooler?

I have a Hinckley & Schmitt Inc. water cooler, the kind where you place an inverted 5-gallon bottle on top, and you have two dispensing spigots for hot or cold water, and the thing works perfectly.

But, when I purchased it from my friend, it had no owner’s manual, so I don’t know how to clean the thing, how often it should be cleaned, nor what substances to use, when cleaning it.

If anyone can advise me about such things, I’d be grateful.

I don’t know if the company exists anymore; it’s my understanding that they were absorbed by some Japanese conglomerate.
