20. Scheduled operations
Both laser clusters are cooled by a liquid thermal system. This system is built up by single circuits, consisting of fan, radiator and
pump. There are two such single systems on each laser cluster. The pump is directly installed to the clusters; a thermal conductive
compound is used between the pump and the cluster to ensure good thermal connection.
In order to access the laser clusters, PCB main including sheet metal brackets and main PSU should be re-
moved, following the steps in Chapter 20, “Technical Operations”.
The procedure is identical for both the laser clusters.
1. 1. Disconnect 2x3 power connectors on each laser bank, indicated by red ovals on the picture below
2. 2. Remove 4+4 screws (T10 M3x10 w/washer), securing the liquid cooling pumps to each Blue laser cluster. Use an X-sequence
(diagonal sequence) when loosening the screws.

3. 3. It may be easier to release the cooling pumps if the copper surface of laser cluster has been pre-heated. Use an adjustable
heat gun set to 80°C - 90°C (176°F). Preheat the pump and copper plate for approximately 2 minutes. .
4. 4. When the copper plate has reached the wanted temperature, carefully pull the bracket in order to release the pump from the
laser Cluster.
