Selection & installation notes
- The naming guide maps voltage code 1 to 110–120 VAC and 2 to 220–240 VAC, but the table puts both ranges against F2 models. Do not treat one unit as automatically dual-voltage; confirm the order code and nameplate.
- The source both requests earthing and calls the unit Class II. Follow the confirmed manufacturer instructions for the exact unit.
- Use ON/OFF control; the source excludes voltage control and PWM. Keep airflow unobstructed and allow clearance around the hot outlet.
- Repeated thermal trips require inspection of fan and airflow. The published life figure is not a warranty or independently verified test result.
