Only for the matching installed component and machine configuration. Verify the existing listing’s part-specific dimensions, materials, ratings, mounting, connections, installation conditions and exact machine serial/revision before ordering. Existing exclusions remain controlling; model name, capacity or shared frame alone does not guarantee fitment. Shared frame or chassis does not establish identical still/control-system revisions or still-volume arrangements; confirm the installed component. Confirm the exact still/control-system revision and installed component; a model-capacity or still-volume variation does not establish interchangeability. Confirm capacity against the machine data plate and exact configuration.
Installation & Ordering Verification
Disconnect power and follow machine safety procedures before servicing door/interlock switches.
Confirm part number 0314007, Z-15 GQ21-B marking, or legacy reference E1712.
Compare actuator style, terminal layout, mounting holes, and electrical rating.
After installation, verify the door/interlock circuit operates correctly before returning the machine to service.
