Please read the instructions carefully and make adequate preparations before use

2. Add the water first, then add the antifreeze liquid.

3. Open the chiller, let the water circulate for 5-10 minutes, then you can start work.

Note:

1. Antifreeze fluid can degrade over time, increasing its corrosiveness and altering its viscosity. Regular replacement is essential. We recommend changing the water every 2-3 months at room temperature. When temperatures rise above freezing, circulating cooling water can be replaced with softened water, such as distilled or purified water.

2. Consistency is key: Use the same antifreeze brand. While main components may be similar across brands, additive formulas can vary. Mixing different antifreeze types can lead to chemical reactions, precipitation, or bubbles.

3. For extended periods of non-use, drain the water from the laser tube, water chiller, and water pipes, especially for glass laser tubes. Failure to follow this procedure can result in laser tube damage, which is not covered by warranty.

This product should be used undiluted only when necessary. When freezing is not a concern, the system should be flushed and refilled with distilled water.
