Thank You Mr Food Scientist!
The link you gave me was very helpful.
It told me pretty much how to make sense
of things. Except one thing; I don't seem to
have a carbonator
Let me go over what I have again in a little more
detail, and let's see if it makes more sense now
So in the first Pic we have the front of the fountain
machine with the dispensing faucets and pumps/valves.
You can see the hosing feeding the dispensing Faucets
behind and beneath them. They lead into and out of
a cold plate chiller heat exchanger.
The second pic shows the inside of the ice bin body of the
fountain machine that cools the cold plate heat exchanger.
The third Pic shows the back of the machine, and the hoses
coming from the front of the cold plate chiller. There is
one hose for each of four types of syrup, one for carbonated
water, and one for plain water (I think)
The fourth Pic shows the hoses draped around to the front
of the machine. You can see that there are four syrup hoses
and two other hoses.
The fifth pic shows the syrup pumps sitting on top of the
soda fountain. I don't know where this would normally be
installed. It also shows the syrup hoses that would come
from the bag-in-a-box syrup containers. The hose on top
must the a CO2 hose that drives the syrup pumps.
The next pic shows the hoses that come from the back of
the machine again, and three regulators that came with the
machine. The main regulator has a sticker that says set to
100 PSI. another regulator says set to 55 lbs. The third
regulator has no label. I don't know how these were hooked
up, or where they were physically installed..
The next pic shows the two extra tubes from the back of the
fountain machine hooked up to two kegs. The small one is a
regular pinlock soda keg with a hose labelled 'plain water'
connected to the CO2 connection!!!
The larger keg has ball lock fittings and one of the extra hoses
goes to the Liquid ball lock fitting (the other extra hose from the
fountain goes to the pin lock soda keg) On the CO2 ball lock
fitting is a a CO2 gas hose with several fittings in the last picture.
The CO2 gas hose has one mainline that goes to a CO2 cylinder.
One line has to go to the syrup pumps on top (currently disconnected).
One line goes to the large keg. That leaves one unused offshoot???
Should that be connected the the pin lock keg instead of the hose
labelled 'plain water'???
The other thing is that if all the CO2 connections are connected to
this CO2 manifold, why are there three regulators, with at least
two of which are set to different pressures???
There's no sign of any carbonator, or any electrical components.
What do you think?
Thanks, Jim.
