Control of water level
To control the level of cooling water go into service menu and check the “filling level”
parameter. If parameter indicates WARN the laser device can still be used without any
constriction, it’s just a sign to refill de-ionized water soon (chapter 6).

Draining the water cooling system
7.1
Seasonal draining of cooling water
Depending on the outside temperature while laser transport, the water of the cooling unit
should be drained.
At cold outside temperatures it is important that no water is inside the laser pump, the
water pump, the de-ionization cartridge, the heat exchanger, and the tank. A frozen
damage at one of the laser parts is irreversible.
•
Summer time: for transportation in a temperature range above 0 °C remove the front
cover (chapter 5.1) and drain the water.
•
Winter time: for transportation in a temperature range under 0 °C drain the water.
Remove the de-ionization filter and ensure that the remaining water is out of the unit
(see 7.3).
