Here’s a checklist:
Maintenance records: Keep a record of maintenance activities to track the air curtain’s performance and plan future maintenance.

Motor and fan inspection: Check for signs of wear, misalignment, or damage. Lubricate moving parts if necessary.
Electrical connections: Verify secure connections and inspect for signs of wear or damage.
Airflow direction: Ensure the air curtain is blowing air downwards to prevent heat transfer.
Noise checks: Listen for unusual sounds indicating potential issues.
Visual inspection: Look for signs of wear, rust, or damage on the exterior and interior.
Control system checks: Verify the control system is functioning correctly, including thermostats, sensors, and timers.
