Upper Control Box Warranty Procedures

When it has been determined that a failure has occurred in the upper control box, only the defective component will be covered and not the complete SUB-A9 assembly. You will have the option to diagnose and replace the defective component and file a warranty claim for labor, or return the complete box to us for component replacement. Labor will NOT be paid on complete boxes sent to us for repairs.

Any SUB-A9 upper control boxes returned to us under warranty will be repaired and returned to the customer within 30 days. We will not be replacing the control boxes as a complete unit.

It is recommended that distributors with more than 10 Hy-Brids in their rental fleet stock a new SUB-A9 in their inventory along with the individual components that make up the upper control box. This will prevent having a unit down in the event that a control box is sent back to us.
