1. Turn Chameleon to Standby.
  2. Switch off chiller and disconnect power line.
  3. Disconnect the coolant lines, ensure that they are labelled so that they are re-connected to the same positions.
  4. Dispose of the spent coolant from the chiller tank into the appropriate waste disposal bottle (stored next to the new coolant). IMPORTANT: it contains Ethylen Glycol, therefore it is harmful for the environment.
  5. Re-fill chiller with coolant ~325 ml.
  6. Re-connect the coolant lines to chiller.
  7. Re-connect power line and switch on chiller. Check that the flow is ok.

Coolant last changed on: Check lab calendar. Changed every 3 months by Erika / Istvan.


Perform a “data run” to check the laser performance every time you do a coolant exchange. As parameteres use every 10nm, 10sec. If you get close to 2W internal power it is fine.
