Unpacking
Remove all packaging material and dispose of it according to standards. Check for any damage incurred during transport and inform the dealer immediately if damage is found.
Assembly
Heaters may come with handles and supports. If the heater is not equipped with a power supply cable, use only cables and components compliant with local and national electrical directives. Incorrect connection can lead to damage or injury.
Operation
WARNING: Ensure the power supply cable is intact and matches the heater's technical data plate.
- Switch-On: Connect the heater to the mains. Turn the power selector to the desired mode:
- VENTILATION: Fan operates only.
- I: Heating power 1.

- CAUTION: The heater has sensors that stop it in case of a serious fault. Resetting is manual: wait for the heater to cool down completely, eliminate the cause of the fault (e.g., blocked air vent), and gently press the 'RESET' button. If the heater does not work after a few attempts, contact the support centre.
- Switch-Off: Set the power selector to “0/OFF”. Allow the fan to run until it stops completely. Disconnect the heater from the mains only after the fan has stopped moving. Incorrect switch-off may block the product; press 'RESET' to unlock if necessary.
