6 Maintenance and service information
Under normal operating conditions the only regular maintenance task is the replacement of
the replaceable protective window of the camera unit. If liquid cooling is applied, cooling
liquid needs to be checked and changed regularly and also the cooling channels need to be
checked and cleaned up regularly.
Changing the protective window of camera unit
Sometimes the protective window of camera unit becomes so dirty that it must be replaced.
Follow these steps to change the protective window:
• Slide the used protective window to either side to remove it
• Check the condition of the fixed glass filter behind the protective window and clean it
if needed
• Slide in the new protective window from either side. Do not touch the surfaces of the
window to keep it clean
Cleaning optical surfaces
For optimal performance it is important to keep the following optical surfaces clean:
• fixed glass filter in the camera unit (behind the replaceable protective window)
• replaceable protective window in the camera unit.
Clean these sensitive optical surfaces primarily by using clean and dry pressurized air. If this
is not sufficient, try dry optical wipes. If needed, the optical wipe can be moisted. Do not use
strong solvents as they may damage optical surfaces. Be careful not to create any scratches on
optical surfaces, as this will deteriorate the performance of the system.
Cleaning the system
Clean casings with slightly moist wipe. Avoid using strong solvents. Ensure the system is
fully dry before connecting it to mains supply in order to avoid the risk of electrical shock
(pay special attention to connectors).
Other maintenance or service needs
In case any other needs for maintenance or service appear, please contact your vendor or
Cavitar (see Chapter 7 for more details).
