Rack Defrost Timer Help

[GenesisRefrig]

I haven’t seen one of these in years. We just picked up a small grocery store, and these are the timers on their racks. I know nex to nothing about them. If anyone has documentation or a link, it would be greatly appreciated.

I am so ignorant about these that I don’t know how to set the number of defrosts, manually initiate a defrost, set defrost duration, wait a minute.... all I know how to do is take a picture.

And I thought Digital Rack Controllers were complicated. You could end up on the Moon by setting that thing.

We still have a couple out there. Hard to get parts for them now though.

If it ever craps out I think you can still get the Paragon version of that setup.

If you look under the top dial there is a black flipper that the cog hits to initiate defrost you can use a pen and push back it will initiate defrost without screwing with your time. Last I knew uri stocked them but they don’t seem to be as well built but beat the hell out of precision ones imho

I've never seen one of these and if staying in my present facility never will, but damn those are some complete explanations, diagrams and instructions!!
Interesting stuff.

We have a few places with those yet. Get all of the times set correctly. One dial is defrost frequency, the other is duration. As someone said, pushing the black flipper initiates a defrost.

Thanks everyone for the replies. Like I said, it’s been almost 30 years since I’ve seen one. I don’t think I’ve ever worked with one. As always, lots of good information here.

We have a customer with these as well, they drive me nuts.

Sliding pin on small wheel is your failsafe setting in minutes. Black plastic tabs on big wheel is when defrost initiates.

From what I remember precision sold them in banks and paragon had the module. You could replace or add 1 without getting a second mortgage.
