Manufacturer schedules assume ideal operating conditions. Increase inspection frequency if your system experiences high cycle counts (>300/year), operates in extreme temperatures (>35℃emaw<0°C ambient), or has experienced any previous faults requiring repair. Additionally, systems that generate critical revenue (primary grid services) or support critical loads (hospital backup power) warrant more conservative inspection intervals than specifications require.
