Changing the Ion-Exchange Resin and Replacing
the Ion-Exchanger
The ion-exchange resin in the ion-exchanger has a function to keep high purity by
removing the ion generated by deteriorated cooling water. Change the ion-exchange
resin with a new one within 6 months after use.
For the ion-exchanger of this laser, the cartridge type is adopted. This type can be
repeatedly used if the content (ion-exchange resin) is changed.
Replace the ion-exchanger every 3 years.
⇒
Keep the ion-exchange resin for change in a cool place without being exposed to
direct sunlight if possible. Do not freeze the ion-exchange resin to avoid lowering
its performance.
Item required
Ion-exchanger mounting/removing tool, ion-exchange resin for change (or cartridge),
cooling water (6 liters), Phillips screwdriver, water feed pump, and gloves (vinyl)

Removing the Ion-Exchanger
(1) Open the cover of the cooling water tank and take out the oating panel.
⇒
Keep the panel clean during the exchanging work.
(2) Pump out water in the tank.
(3) Turn the ion-exchanger in the tank to the left with the replacing tool to remove it.
⇒
For changing with a new ion-exchange cartridge (with resin for change), proceed
to Step 3.
