If it is a variable speed motor than you'll also need filters on the wires.
I think it is worth contacting the installer and trying to get a
non-variable
speed motor (though the utilities prefer the variable speed because it
is more efficient and can be run at different power levels as desired ...
in some cases they can control the power remotely!).

If it is variable speed, it is also possible that on maximum speed it
will be OK.  You should be able to tell with an AM radio.
