⚠️ Please note: These instructions are only for our Ruben telephone box (Lendis ID: 00000013, see picture). For all other telephone boxes, you can regulate the ventilation using the rotary knob on the ceiling of the telephone box.
📝 Instructions:
If the ventilation is set a little too strong, you can regulate it on the roof of the telephone box. Proceed as follows:
Place a ladder next to the telephone box to gain safe access to the roof of the box.
On the roof of the box you will find the following switch
- With this switch you can regulate the ventilation in three steps
- Left = strongest speed
- Middle = Medium speed
- Right = Lowest speed
The switch has always been set to the maximum level during installation.
