It is necessary to join the pipe, junction and cap with PVC glue. For the lens, we have used Kafuter K-303 glue, because it joins the PVC of the pipe and the PMMA of the lens very well, without yellowing with solar radiation. Remember that this glue dries with UV light. Next, place the chassis with the electronics (you can rotate it if you notice that it may be off-centre) and use 3 screws to secure it. Make sure that it goes smoothly into the tube, which will allow the sensor to be well centred. |
