The other thing with reverse osmosis systems, is generally they don't remove 100% of the minerals. If you check with a TDS Meter (total dissolved solids) your incoming tds may be 300, and coming out of the RO may be 50.

Yeah, 50 would be the highest I'd like to see out of an RO system working properly, for scale reduction. Course, when you get really low, and you have exposed probes, they may not conduct.
I had a kettle at a place, they wouldn't replace it, even though it would blow it's water charge out every week or so through a pinhole at the bottom.
We always replaced the water with distilled, and after a few weeks, I couldn't get the silly thing to believe it had a proper water level in it. Added a pinch of salt, and they were good for another week. :)
Yes, that's the original linear acutuator, on the Gen *1* LOV's, in 2007 maybe?. Hey, I'm old. :) At that time, they had not been selling them to the general market yet.
They didn't have the gas ones ready then, I saw one in the test kitchen though. Looked like a real bear to work on.
Yeah, the rotory actuators are better.
I believe the AIF's are only McD. I've put in some JIB / ATO only units at burger kings, I think.
Great discussion here guys.
Also remember that distilled water is the only way to stop galvonic action in any body of water. So even a boiler with RO water feeding it will still have to have the corrosion inhibitor replaced as with any normal water supply.
If the water will conduct for the water level circuitry, it will conduct the naturally occuring galvonic currents. (Galvonic corrosion/electrolysis)
Boiler plate steel is not as weak as magnesium (corrosion inhibitor for most boilers), but its close. You'll have no scale but your boiler shell will still corode away.
Just no way around proper maintenance.
I'm afraid to see these LOV's in ten years. The only ones I've worked on are at Mcd's. Some of the ones at the busier restaurants filter a lot of times in a day, and will take out a pump/motor in under a year.
In my opinion the electronics are a little overcomplicated. I've worked on a couple of Henny Penny LOV's in Mcd's that where out of warranty. The Henny Pennys seemed easier to work on than the frymasters, and seem to be holding up pretty good.
Can't disagree. Those fryers up front doing french fries see a ton of filter cycles. The good thing for the pumps is that there's no chance of Frank-the-fry-filter-person leaving the drain valve and refill valve open, and taking a 20-minute break, with the pump just a chooglin away.
I've only worked on the older Henney Pennys at Wendys, and I loved how the contactors were right up front.
What does it mean check S C pump??? on a SCC102G Rational combi oven
There's a pump that periodically empties the steam generator of its water. It's called the self-cleaning (SC) pump. When the controller calls for that function, it monitors its water level with the water probe. If the controller doesn't sense the water level drop after adequate time, it shows the error code that the pump isn't working.
The usual cause of its failure is limescale jamming it up.
