Re: warning horn location
I should be a little a small box located towards the top of the control box. It will be mounted to the side you can remove. It will have 2 wires going to it. If you look at it from outside of the control box it may have several small holes drilled into the cover of the control case, or it may be one hole. The horn itself is about the size of a home fire alarm horn. It's just a small metal diaphragm encased in a small box about 1 1/2" X 1 1/2".
