Environmental Maintenance

Hot and Humid Months

During hot and humid months moisture can build up on the water hoses in the laser tube cabinet. Adjust the chiller temperature to be 1-2°C above the dew point.

You may want to add algaecide to your water to decrease the chances of algae growing in the laser tube.


  1. Drain all of the water from the Chiller
  2. Add 2-3 drops or 1 tablet of aquarium algaecide per gallon of distilled water to the water
  3. Refill the chiller with the algaecide/distilled water mix to fill line

Recommended Algaecides

Cold Months

During freezing months take extra care to make sure your machine is not in an environment that goes below freezing, as this can cause the water to freeze and crack the laser tube.

If you are keeping your machine in a room that is subjected to cold temperatures, we recommend preparing your machine for the dropping temperature by adding antifreeze to the chiller. Please follow our Winterizing Guide for instructions on how to do best this.

If your machine is going to be in an environment that is at or below freezing we recommend you contact Customer Support at support@aeonlaser.us for instructions on how to prepare.


  • During extreme temperatures ensure that the exhaust duct hose is disconnected from the machine so that the outdoor environmental air does not connect directly to the machine.
  • Drain all of the water out of the Chiller.
  • Cover with blankets.
