Maintenance Tips
-
Run weekly exercise cycles: Use the App Connect / Energy Management or RDC2 controller to schedule weekly test runs — this keeps internal parts lubricated and ensures reliable starts when needed.
-
Change oil & filters regularly: Follow the service schedule (typically every ~100 hrs or annually) to replace engine oil, oil filter, and air filter to protect the Series 7000 V‑twin engine and prolong life.
-
Keep battery charged & terminals clean: A healthy starting battery is essential for automatic operation; clean and tighten terminals to prevent corrosion.
-
Inspect fuel lines & connections: Check for leaks or blockages in natural gas/propane supply to maintain steady power delivery.
-
Clear air intake & enclosure: Remove debris and dust from ventilation openings to support proper cooling and reduce noise.
-
Monitor via app alerts: Leverage the remote monitoring app to track status, exercise cycles, and maintenance reminders without on‑site checks.
-
Check transfer switch & wiring: Periodically verify that the automatic transfer switch and electrical connections are tight, corrosion‑free, and functioning correctly.
-
Annual professional service: Have a certified technician perform yearly comprehensive inspections and service to uphold warranty and performance.
