Installing a New Flashlamp
(1) Wipe a new flashlamp with alcohol and pass it through the flowtube.
(2) Adjusting the polarity of the flashlamp to the + sign printed on the laser chamber,
return the flashlamp slowly into the laser chamber.
⇒ Check the polarity of the flashlamp. The red painted electrode is the positive
side.
⇒
When returning the flashlamp into the laser chamber, set the lamp-side fixture
correctly in the chamber-side fixture.
(3) Tighten the bolts on both ends of the flashlamp to fix the flashlamp.
⇒ Tighten the positive side and the negative side little by little alternately with a
tightening torque of 60 cN•m (6 kgf•cm).
(4) Put the top part of the reflector slowly.
(5) Wipe off the waterdrops attached on the rear side of the top lid of the laser
chamber, and then install the top lid of the laser chamber.
⇒
Tighten the 4 bolts with the standard tightening torque of 500 cN•m (50 kgf•cm).
⇒ If water leakage occurs during an operation check, tighten the 4 bolts within the
maximum tightening torque of 550 cN•m (55 kgf•cm) and the make sure that no
leakage occurs. At this time, the packings between the top lid and the chamber
are equally pressurized.
