- Installation guidance for SM343-SU. This is a preparation checklist, not a model-specific service procedure. Confirm the appliance model, original part number, dimensions, fan blade, connector arrangement, and electrical ratings before installation. Obtain the manufacturer's instructions for that exact model. Disconnect electrical power before service. Follow the exact model instructions for access, removal, mounting, and connections. Do not force a similar-looking kit to fit, improvise wiring, or bypass a fuse, control, or safety device. Reinstall guards and panels, then complete the manufacturer's safety and operating checks before returning the appliance to service. If the exact procedure or compatibility is uncertain, stop and contact the appliance manufacturer or a qualified service technician.
