EcoSmart unit is warm or hot to the touch on the outside cabinet during operation.

Safety: Mild warmth can be normal; excessive heat should be investigated with power OFF.

• Check clearance: Ensure the heater has the recommended clearance from walls and other objects for proper cooling.
• Inspect internal insulation: With power OFF, open the unit and verify that any factory-installed insulation panels are in place and not displaced.
• Ventilation: Improve airflow in the installation area if it is confined or very warm.
• Monitor temperature: If the cabinet becomes too hot to touch, discontinue use and have a technician check for overheating components.
