Additional Information

Changing The Water

Change the water (distilled only) and clean the filters on the sides of the chiller. The filters allow for air flow to help the heat exchanger work at optimum performance. If you are in a dusty environment, you may need to clean them more frequently. The water is changed to prevent Algae buildup. You should target changing your water every 3-4 months. If you do develop an algae build up, you will need to perform a system flush.

You will need about 1.5 gallons of distilled water every time you change your water. The chiller does not consume water, so you should also empty out the same amount of water.

If water drains slowly from drainage nozzle during water changing, please remove the silver fill cap.
