That sounds good, but you want to be sure the unit is mounted so it motor vibration won't be transmitted into your home.
I used some coroplas (stuff used to make signs) to block snow and rain, (gutter over-flow)
and it
conducts sound into the house.
The top edge is now taped to the siding. Our bathroom is on the other side of the wall.
There are times when the Sanyo is really cranking, the low frequency vibrations are very noticeable.
Especially when you are in the bathroom. Loud enough, so I wouldn't want it near my bedroom..
It's not that Sanyos make a lot of noise, they don't.
But, the motors and their conducted vibrations, can turn the wall into a big speaker-like surface.
Stand next to the Sanyo outdoors, you can hardly hear it.
But in the bathroom it's really drumming on the wall..
This isn't a problem with my other Sanyo, it's case is free standing.
Not connected to a rain roof..
That sheet of coroplas isn't that big of a conductor. It's not rigid, it's very flexible.
But, it's enough to make me want to replace it with a free-standing roof..
