HEATER ELEMENT CHANGE
When a faulty heater element is found, it must be replaced as soon as possible.
If the star point is not connected, there is a risk of a knock-on effect in which the other heaters will also break down.
This operation can only be undertaken once the electrical supply has been switched off (consignation).
Remove the defective heater and clip in the new heater.
