Ive just put a pid on my isomac napolissima, works awesome, didnt realise the difference it would make, just to know the actual temp of the boiler and group head is a big bonus not to mention having control over it as well... The machine cost me $125 the pid $40 the ssr $40 to fit it etc... $50 total $255 and very happy.........

Re: pid isomac napolissima
All came from that other place, where you bid for things. The machine was $125, the pid $40, ssr $40 fitting $50. Total $255... and very happy, pulls an awesome shot of coffee, cant believe the difference, has a brass boiler bolted directly to the top of the group head, good stable arangement...
Also produces a great head of steam although takes about 30 secs to develop....

Re: pid isomac napolissima
Im really not sure about the 3 way valve thing, I think its a 6900 or 6910 thing...... maybe I need educating further on this matter myself... I can tell you that the steam and group head work separately... but has one boiler.

Re: pid isomac napolissima
Gday ray,
One way to tell if your machine has a 3-Way Valve, is when you pull a shot on the napo, does it exhaust the pressure away from the Group/PF immediately you turn the Brew Switch off so that you can immediately remove the PF or does the pressure remain built up in the Group for a while after switching off the Brew Switch?
If the former, then your machine does have a 3-Way Valve... If the latter, then your machine does NOT have a 3-Way Valve. The main purpose of the valve is to allow the user to immediately remove the PF after pulling a shot instead of having to wait until the pressure in the Group has dissipated. Sort of a time efficiency thing handed down from commercial machines.

Re: pid isomac napolissima
Thanks Mal, no it doesnt exhaust the group head pressure away, it has a very slight pressure build up when the group handle is removed unless you wait a few seconds for it to dissipate... having said that then I would say the answer to the question is "41" ha ha ha... (hitch hikers guide to the galaxy thing) that no it does not have a 3 way valve....

Adam, 58mm, 61mm would have been very nice though but for the $ its all good, I just love it. Am considering getting another one as a back up or a christmas present for someone... I would love to know who the destributor or importer is, it is made in italy, but someone must be getting them in.
