Water quality
Over time, the chiller water can become cloudy. Cloudy chiller water is no longer good for
use. Replace with deionised water only.
1.
Remove the reservoir cap.
2.
Open the valve at the bottom of the chiller to drain all the chiller water.
3.
Unplug the blue tube. Use compressed air (max 2 bar) to blow out the remaining water in
the laser unit.
4.
Plug the blue tube back in.
5.
Flush the chiller with clean tap water once, then close the drain valve.
6.
Refill the chiller with demineralized water. The reservoir holds approximately 22 litres.
7.
Close the reservoir cap.
If desired, glycol can be added to the water to reduce bacteria growth. The ratio is 1 part glycol
to 10 parts water.
4.3.1.3
Water pipes
To ensure proper water flow, the water hoses need to be in good condition and without kinks
or sharp bends.
