A few weeks ago I posted a blog entry with a few images of the upgrades that we would be making to our October 2003 Cremina to bring it right up to date with the current model.

I can't remember whether I posted that my efforts to complete the addition of the 'u-bend' copper pipe to turn the p-stat up the 'correct way' were thwarted by discovering the wires connected to the p-stat were too short on my machine to allow me to raise the p-stat up the new position it now needs to be in.

Anyway, we obtained the longer wires as used on the current production model Cremina and finally had a chance to finish the mod today.

As usual the photos tell the story far more succinctly than words, so without further ado, here are the necessary images.

Before: (note that the adjustment screw is on the underside of the mater pressure stat in this image)

Bother!  (Wires too short to reposition)

Short red wires replaced with longer ones, allowing the pressure-stat to sit up the right way.  Note:  there is only 2mm between the pstat and the boiler and another 2mm between the other side of the pstat and the casing (when fitted) - so you need to get it positioned in exactly the right spot before you tighten up the olives on the brass pipe.

After: You can see clearly that it is a snug fit, so positioning is critical if you are to avoid the pstat to sitting against the boiler, yet be able to get the cowling back on.

As you can see from the before and after images it is now a lot easier to adjust the p-stat as we no longer need to remove the cowling, just the top plate.
