You need to add purified water, as non-purified water will affect the lifespan of the CO2 glass tube. Purified water has superior thermal conductivity and fewer impurities, which can improve heat absorption and transfer. First, turn off the power, then open the water tank cover.
First Water Filling：
First, add 1000mL of distilled or purified water, then securely close the water tank cover. Connect the power cord, turn on the power switch, ensure the
emergency stop button is in up position, and turn the key to the ON position to start the machine.
Second Water Filling：
After the machine has been running for 10 seconds, turn off the power, continue adding water until the water level is between the minimum and maximum water level lines, securely close the water tank cover, and properly install the filler cap. Water filling is completed.
