## Questions & Answers

**Q: how to remove the cover from a monsoon electric fan - it does not have two serrated clips - just a small hole in one side**
A: Hi.
The one I took off as the fan had failed and I was replacing the whole unit, so I wasn`t too bothered about any damage. As you say it`s not obvious, so I got a wide, flat bladed screwdriver and went in the side, under the outer cver and twisted and it just seemed to pop off. The new one I have not pushed home completely in case I need to get that off at some time. Good luck.

**Q: how to remove cover from a monsoon extractor fan**
A: My husband has done this. There are two small slots either side. You insert a screwdriver and prise it off. One side then the other side. It just clips off and on.
