It is recommended to install the laser in an air-conditioned environment so
that the laser can operate under optimal conditions.
Do not expose this product to high humidity（＞70%）
Do not expose this product to high temperature（＞40%）
Do not let this product work below the ambient dew point
temperature
Table 4 The Constant Dew Point Table
The necessary moistureproof treatment has been done in the design of the
laser, but the influence of too serious condensation cannot be avoided 100%.Since
condensation is an objective physical phenomenon, there are usually two ways to
avoid it:
（1）The water temperature of the water-cooling machine is higher than the
dew point temperature, but it should meet the cooling requirements of the laser.
Therefore, in the corresponding environment, the water temperature of the laser
can only be set in the blue region of the dew-point comparison table, so this
method has certain limitations.
（2）By changing the temperature and humidity of the working environment
of the laser and reducing them through air conditioning, the water-cooling
temperature of the laser can be relaxed and the water temperature can be far away
from the dew-forming temperature.

2.6 Specifications
（1）Ensure reliable grounded before using the laser.
（2）Before supplying the power to the device, make sure that the correct
voltage of the AC power source is used (220VAC or 380VAC). Failure to
connect power source correctly will damage the device.
（3）When the laser is in running state, do not touch the laser machining head.
（4）Do not look directly at the output head. Make sure to wear laser protective
glasses when operating the machine.
（5）Please inspect the output head carefully for dust or other contaminations.
Use appropriate lens paper to clean it if necessary.
（6）The high temperature laser in summer is easy to produce dew and cause
permanent damage. Please make sure that the water cooling machine
stops at the same time when the laser stops.
（7）The freezing of cooling water inside the low-temperature laser in winter
will cause permanent damage. Please ensure the continuous operation of
the water-cooling machine under the shutdown state of the laser.
（8）Failure to follow the specified instructions may result in the loss of laser
power, and such loss will not be covered by the warranty.
