cover.
If a noticeable drop in laser energy has occurred, it may be necessary to
flush the cooling system to remove any contaminants. Carbon dioxide
from the air and metal ions will naturally collect in the cooling water
over time. The cooling system can be cleaned using a dilute acetic acid
solution. Follow the procedure below to flush the cooling system:
1) Turn the flashlamp voltage knob on the control fully
counterclockwise to the minimum.
2) Disconnect the lower WATER RETURN hose from the back of the
power supply and hold it over a drain container.
3) Depress the START/STDBY button on the control panel to start the
pump. The pump will force the cooling water from the hose into the
drain container.
4) Remove the water out connection on the back of the power supply.
Use clean compressed air or nitrogen to blow the remaining water
from the laser head umbilical tubing. Also, blow clean compressed
air or nitrogen into either hose fitting on the back of the power
supply. Additional water will be forced into the reservoir. Remove
this water with a syringe.
5) Turn the power supply off with switch at the AC power entry module
on the back of the power supply, and disconnect the AC power cord
from the power supply.
6) Clamp the water supply hose leading to the deionization cartridge at
the T connection, Figure 5-2.
7) Reconnect the laser head umbilical hoses and power cable to the
power supply.
Ensure that the deionization cartridge is bypassed before any acetic
acid is added to the cooling system. Acetic acid will destroy the
deionization cartridge.
