Notes from the research
  • No Rocket-hosted manual exists for this model; every value comes from Rocket's own range manual rehosted by a retailer, so the basis is community by host.
  • Drip tray has a procedure but no frequency; group-head wipe, water-filter replacement, boiler water change and professional service are not stated.
  • s2 (the edition that names the Cronometro V/R) has a corrupted text layer (missing letters), so its identical maintenance chapter cannot be quoted; values are quoted from the 2019 edition (s1), which names the Mozzafiato Type V / Evoluzione R, not 'Cronometro'.
