You will also need a screwdriver set with bits T8, T10 and PH2.

Step 1: Remove defective solenoid

Use the screwdriver bit T10 to unscrew the 4 screws of the centrifuge lid (Fig. 3).

    Remove the plastic cover and the centrifuge window.

    To easily remove the plastic cover, push the window from the back of the lid (Fig. 4).

    Place the Bento Lab resting on the hinge side, so you can easily work on the centrifuge lid.

    Remove the old lock assembly:

    Use screwdriver bit PH2 or T8 (depending on your lock version) to unscrew the 2 screws securing the lock assembly to the lid. These 2 screws will be discarded and replaced by the new screws in the kit.

    Disconnect the 4-wire cable from the old lock.

    Cut the 2-wire cable at the point shown in the picture, Fig. 7.

    Step 2: Connect the 2-wire cable to the new lock

    Prepare the wires

    Using the supplied stripping tool, strip around 4-5mm of the plastic insulation from the red and black wires.

    To do this, insert the wire into the smallest hole on the stripping tool as shown, press firmly and pull the insulation off. You may need a few attempts. The end result should look like the second picture.

    Connect the wires to the new lock

    Place the stripped wires inside the white terminal of the new lock.

    Press the clip down to insert the stripped wire inside the terminal. Ensure to match black with black and red with red.

    Then, connect the 4-wire cable to the new lock.

    Step 3: Reattach the lock to the lid

    Fasten the lock assembly to the lid using the 2 screws supplied with the kit.

    Use screwdriver bit T8, and use the new screws supplied with the kit instead of reusing the old screws.

    Fig. 12. Lock assembly reattached to the lid using the two new screws.

    Arrange 2-wire cable as shown in the picture, under the lock assembly and around the white boss (the raised cylinder). This ensures the 2-wire cable does not get in the way while replacing the lid cover.

    Attach the terminal

    Peel off the double-sided tape on the back of the white plastic terminal and attach it to the bottom right corner of the lid. Be careful to position the terminals in the right position, as the tape is very strong.

    To ensure the 2 wires cable at the bottom of the lid does not get in the way while closing the lid, arrange it as shown in the picture.

    Replace the window and lid

    Put the clear window back first. Then mount the plastic cover from the bottom first, then push on the top of the cover to squeeze it under the lock body.

    Finally, use screwdriver bit T10 to refasten the plastic cover using the original four black screws (as shown earlier in Fig. 3.).
