Removal Procedure

1. Put on proper PPE.
2. Remove the Reagent Bay module.
3. Disconnect the motor and optical sensor from the PCB board on the rear of the module by gently pulling on the connectors.

   

4. Using the 2.5 mm hex driver, remove two 3 mm socket head cap screws that secure the optical sensor to the motor bracket and remove the sensor.
