The product brochure Juan linked to shows RFI filters as accessories. It
appears they need to be ordered separately and assembled on-site. The
installation manual may also specify that the motor leads be shielded. That
is a common requirement for this type of device--one often ignored by the
installers, to save time and money.
So the first step is to be sure the unit is installed as specified by the
manufacturer, including all recommended filters and wired per the manual.
