CHAPTER 2: INSTALLATION AND SETUP
LW500A/LW600A PULSED Nd:YAG LASER
2-6 990-539
Connecting the Hose for Primary Cooling Water
Connect the supplied 19mm braided hoses to the cooling water inlet and the outlet on the rear of the Laser.
Tighten the hoses using the supplied hose bands.
NOTE
Use city water or water for industrial use, as the primary cooling water, with a
pressure of 42.6 psi (294
kPa) and a differential pressure of 14.2 to 42.6 psi (98
to 294
kPa). The required flow rate will vary depending on cooling water
temperature. Refer to Appendix A for flow rate requirements.
Supplying the Secondary Cooling Water
CAUTION
Use ion-exchanged water or steam-distilled water for the secondary cooling
water. Tap water, water for industrial use, ground water or super pure water (16
M/cm resistivity) and water with ethyl glycol may cause corrosion or clogging,
resulting in a failure.
1. Remove the water tank cover and floating panel from the cooling water tank. Keep clean.
2. Fill the tank with secondary cooling water up to the line reading [HIGH] on the water level gauge
label, using the supplied PH-10 hand pump.
3. After filling the tank, put the floating panel on top of the water. The floating panel helps maintain
a more stable water level, when the water pump is in operation.
4. Re-install the water tank cover back onto the cooling water tank. Once you have supplied the
cooling water and started the Laser, the water level may drop slightly. If so, add more cooling
water. Make sure that the floating panel is removed when adding the cooling water.
NOTES
Only use the supplied PH-10 hand pump for the secondary cooling water. To
avoid contamination, do not use it for any other purpose.
You can use the floating panel repeatedly until it starts cracking or breaking
apart. If the panel becomes stained, clean it using tap water and a soft sponge,
then rinse it with ion-exchanged water or steam-distilled water.
