The DELTA01 Maintenance Alert Assembly is used in the DELTA and A2000 instruments. It includes the Drip Tray w/plugged drain hole (Part #: 692), Agitator Apron (Part #: 638.7), and brass washer and functions as a collector for a fluid leak, diverting it away from the motor. It also serves as an indicator of when to tighten or replace the packing.
