I'm working on a city multi PURY-P300YGM-A. Its cooling fine but not heating at all.
When I began work on the unit I noticed a few things. Firstly the unit seemed to be grossly overcharged. Additional charge labelled was 28kg. Recovered gas, replaced high pressure ball valve (which was partially seized) and re-charged with 14kg additional charge.
I also relplaced the HP sensor, which was reading way out of calibration.
The site is one we have just inherited. It looks like this particular unit has some history as the four way valve looks like it has been previously replaced.
I haven't checked the BC box LEVs yet. That's one for the morning. In the mean time can any of you throw an eye over the attached service checker readings and see if I'm missing something obvious?
