- Electrical Connection: Connect the heater's power cord to a 230 Volt electrical outlet. Verify that the outlet is properly grounded and suitable for outdoor use if applicable.
- Initial Operation: Upon first use, a small amount of smoke or odor may be emitted. This is normal and should dissipate within a few minutes as manufacturing residues burn off.
Operating Instructions

- Power On: Once plugged into a compatible 230V power source, the heater will begin to operate. The integrated thermostat will regulate the temperature.
- Temperature Control: The heater maintains a stable environment. While it has an integrated thermostat, specific temperature adjustment controls are not externally accessible on this model. It is designed to provide frost-free heating and maintain a consistent low-level warmth. For precise temperature set points, consider using an external thermostat controller (not included) with your power outlet.
- Monitoring: Regularly check the temperature in your heated space to ensure it meets your requirements, especially for sensitive plants.
