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.
