Not worried about the frost was just stating it was frost and not ice as before. That usually stock this cooler with 16oz milk on the top then juice. They have are those M&M pie slices and fresh fruit in there. 85% is juice and milk.
With milk and fresh fruit, I'd still be looking for a cut out down in the low 30s.
You need to keep that product at the lowest temperature possible without freezing it.
Milk, fruit and juices have enough fats and sugars in them to lower their freezing point to below 32 degrees. I would not be afraid of a 30-32 degree cutout on that unit.
Thanks for the advice. I will try it and see what happens. Going to let this run over night with no product in it just to make sure the freezing up problem is taken care of.
Just wanted to thank everyone that helped out. Everyone had good advice.
This site is great and I'm glad I found it and will be here till it disappears.
On to the next project.
Just thowing this out there for the other guys.
I had a call bout five months ago,,, open case fresh case freezing product and bursting cans of energy drinks. Its a remote with a Carol electronic controller.
I arrive and the case is off. I restart it and observes operation. Verify that controller is set to southen specs. Deforst every hour, etc, etc.
I do make one change to the unit and raise the differential so that the box gets to 40 during the offcycle to make melts all ice off coil.
Oberve operation and make sure everything is gravy, manually defrost and record all temps to go with it.
Just this week I was replacing a dispensing valve on a fountain at said location and out of habit I walk around the store checking walkins and what not. On my way to the register I notice that the analog display on the case was reading 49 degrees. I whipped out pocket thermo to verify.... Its correct. I then notice that the walls on the case are frosted over. Hmmmmm. Remove the bottom cover to gain access to the electronic controler and it says that it is at 1 degree and currently in defrost. I can hear freon moving, its a remote so it's quiet under there. Give the suction line solenoid a love tap and it seals up and the the flow of freon stops. I verify on the top of the roof that the condensing unit has shut off and it has.
Four months ago I missed this cause the customer turned off the box and while i was there the problem never occured. I blamed the electronic controller and it's set points.
Needless to say contacted the company that sent me out and said I could not fix it cause the store did not issue a work order. I did defrost the box and restarted it and let the on duty manager know of the situation and what would be needed to fix it should it happen again.
Waiting for it to happen again.
And yes,,, it was a suction line not a liquid line solenoid.
