3. You can use vacuum cleaner, air gun and brush to
remove the dust on the filter. After cleaning, if the filter
is wet, please shake it to dry and then install it back.
Prevent poor heat dissipation from
causing poor cooling, and burning
out the water pump and
compressor.
4. Check the water quality of the tank and follow up.
Good water quality can ensure the
normal operation of the laser.
5. Replace the cooling water (distilled or purified water)
and clean the metal parts of the water tank and water
circuit.
1. Check electrical parts (such as switches, terminals,
etc.) and wipe clean with a dry rag.
Ensure that the surface of the
electrical parts of the water cooler
is clean to extend the service life.
2. When the machine is used in winter, replace the
antifreeze and clean the metal parts of the water tank
and water circuit.
Ensure that the laser operates
normally.
Precautions:
Cooling water should be deionized or distilled water, and tap water is strictly prohibited. The cooling water
and filter element of the water cooler should be replaced regularly every month. Adding 5% -10%
anhydrous alcohol to the water cooler can effectively prevent the production of micro-organisms in the
water, thus making the product more reliable.
When the laser is used in summer, pure water should be used as the cooling water to protect the water
circuit of the water cooler from corrosion resulted from long-term use of the antifreeze.
When the laser is used in winter with an ambient temperature below 7 ℃, it is required to protect the
internal water circuit of the laser and the water cooler from being frozen. An appropriate amount of
antifreeze should be added to the cooling water for protection. The freezing point of the antifreeze must
be 5 ℃ lower than the minimum ambient temperature
The water inside the equipment and QBH should be emptied timely before the machine is out of service
for a long period. Otherwise, the water remained in the equipment for a long period may cause damage to
the laser. When the water inside the QBH is drained, the air pressure must be less than 0.1Mpa.
Excessive air pressure should be avoided to protect the optical fibre from being damaged.
When the laser is used in summer, it is required to prevent any internal condensation. Once the cooling
temperature of the water cooler drops below the dew point of the laser's internal environment, the
moisture in the air will be condensed onto the electrical and optical modules. If no measures are taken,
the moisture will be condensed on the outer surface of the laser. Once the condensation is visible on the
laser housing, it indicates that the moisture is already condensed in the laser. In this case, the machine
should be powered off and stopped, and the working environment of the laser should be improved.
To reduce the risk of condensation, connect the clean and dry compressed air line from the CDA on the
back panel of the laser and inject the clean and dry compressed air into the inside of the laser. The air
pressure should be kept at 0.1MPa. It is prohibited to use the compressed air containing water or oil.
