1. Measure the area of the room/room/house to be ventilated
2. Choose the facility that suits your goal
3. Choose the 2V designation if the house has 2 floors (one fan for each floor) or if the house is elongated (one fan at each end of the house)

Advantages of using a solar ventilation kit:
– no maintenance, can be installed by anyone in a few hours
– starts automatically when the sun shines, no power from the mains is needed
Installation instructions for solar ventilation kit (KCV 05, 10, 20, 30, 50)
1. Mount the solar module firmly on the roof, wall or on the desired stand. (Recommended facing south at a 45 degree angle).
Mounting brackets can be ordered separately from the following link: Mounting brackets
2. Mount the fan in a square hole in the wall or pipe so that the air can be blown out of the house. See the marking on the fan. The hole can also be covered from the outside with a reed valve (Can be purchased
in all building centers)
3. Connect the cable from the solar cell to the fan (blue from the solar cell to black from the fan(-), brown from the solar cell to red from the fan (+).
4. The cable (minimum 0.75mm² cross-section) can be extended as needed up to 20m – if, for example, the solar cell is to be installed on one side of the house (south) and the fan is to be mounted at the other end.
5. If necessary, you can install a regular switch between the solar cell and the fan, for example on the plus wire.
6. The fan can be mounted to blow the air out or into the room (e.g. from a covered terrace which gets very hot when the sun is shining). For more power, you can use more solar cells, or if you want more ventilation, you can install more fans.
If you use two or more solar module, they must be connected in parallel, the same if you use several fans.
