IMPORTANT! In order to ensure that you order and receive the correct parts, you will need to confirm the serial number from the motor on your unit as there is an old-style and a new-style motor/pump assy and parts for each are unique.

For example, the label on the NEW-style motors will state "SP-9421 220/60-O" and the OLD-style motors will have a "CNF" on the serial number.
