I was just wondering what is the best temperature to keep the soda machines at? When I got mine, it was running every 20 minutes for 9 minutes. I dialed the cutler hammer down and now it runs every hour for about 9 minutes. The inside temp of the product that comes out is 49-50. It tastes cool enough to me but was wondering if I should dial it down cooler?

I just installed a Coinco 3340-s mech into my Dixie Narco 240/138-6 Pepsi machine. I replaced the Coinco S-75 9800 that was in it because it only excepted quarters and wasn't giving the correct change. The coinco 3340-s was rebuilt and works great. It also has a plug for a bill validator. Now this machine is used for my own home use only so I don't mind if it doesn't take the new $5's and I don't want to spend a lot of money on the validator itself but I was wondering what would be a good compatible validator to get that would work with the coinco 3340-s?

Also I have qustions about installing it as well. There is no slot for it so I would assume I would have to cut a slot or can I buy a part with the validator slot already cut in it? Is there some kind of mounting bracket I would need to get or does it validator self clamp to the door? The validators I seen look like they also get power from the 8 pin jones plug. How can I plug both the validator and mech into one jones plug?
