the water inlet on the laser tube (left side, cathode side).
6. Carefully connect the water tube between the outlet on the rear of the connection panel and
the water outlet on the laser tube (right side, anode side).
7. Connect the high voltage (+) terminal (left side, cathode side) to the power supply according
to the wiring diagram in this manual.
