When the temperature of your working environment fall below 0℃, it's important to prepare your antifreeze before powering on your machine, as the laser tube may crack in cold weather. This precaution safeguards your laser tube from cracking due to low temperatures.

Antifreeze is needed only at a temperature lower than 0. When the temperature goes up to 0℃ or higher, you need to replace the liquid coolant with purified water. Note that you need to remove all the coolant, clean the water tank, and then pour in purified water.

The volume of antifreeze to be used

Reminders: 

• The antifreeze is 99.8% propanediol. Keep it away from fire and direct sunshine.
• It's important to use caution when handling antifreeze as it can be toxic if ingested. It should be stored in a clearly labeled and secure container, and any spills should be cleaned up immediately. It's also recommended to wear gloves when handling antifreeze to avoid skin irritation.
• It's advisable to regularly check the liquid coolant level and condition to ensure proper functioning of the laser tube and avoid any damage or malfunctions.
