With the laser switched off, disconnect the power cable and wait about 15 minutes until the capacitors are completely discharged. The red light on the Flash Lamp Power Unit should be off.

To remove the water container, disconnect the cable with the label J35 on the control board.

In the benchtop model, when the water container is removed, the water pump will be exposed.

Once the water pump is exposed, remove the four Phillips screws that attach the magnetic drive to the water pump.

To remove the clamps, follow the instructions in the image below.
