Instructions
Connect 110V-260V AC power supply for laser operation.
Place the laser in a clean environment with space for sufficient heat dissipation.
Set the environment temperature close to 25℃which is the set temperature of chiller (Generally, 25℃is a typical set temperature of chiller. This value
may vary for different lasers. Refer to the printed report attached with the laser for the real value. ) Set the environment humidity within 10%~80%.
Operation of laser in high/low temperature or high humidity environment is prohibited.
Make sure the power supply of the laser is grounded. Operation of the laser in environment with strong electromagnetic interference is not
recommended.
Always wearing laser goggle when the laser is operating. Staring into the laser output window is strictly prohibited.
Regularly examine of the cleanness of the distilled water and filter. Replace the filter every month. Make sure the water volume, water quality, flow rate
is normal. The laser may be damaged permanently if the water is insufficient in chiller or the water flow is blocked.
Always use packing box provided by Tianjin BWT Laser Ltd. for moving or storage of the laser. Always move the laser slowly and steadily and avoid
sudden shock. Special fixture may be necessary for moving the laser.
Operation Temperature 15℃~35℃。
Storage Temperature－10℃~＋50℃。
