Atlantic water heater outer casing is very hot to the touch during operation.

Safety: Turn off power and allow the heater to cool before touching the casing for extended periods.

• Measure the hot water temperature; reduce the thermostat setting if above 60°C.
• Check for continuous heating (element always on). If so, the thermostat or sensor may be faulty and should be replaced.
• Inspect the installation location; ensure adequate ventilation and that the heater is not exposed to external heat sources.
• If the casing remains excessively hot despite normal water temperature, internal insulation may be damaged; consult an Atlantic service center, as this typically requires tank replacement.
