3.1.4.4.2 Industrial chiller installation:

First fill the chiller with distilled water.

Then, connect the water outlet of the chiller to the water inlet of the machine, and water inlet of the chiller
to the water outlet of the machine with pipes.

Connect a patch board with circuit breaker or overcurrent protection. The input voltage is 220-240V AC,
50/60Hz.

Connect the power supply and turn on the chiller, set the chiller temperature at room temperature ±5°C, and
adjust between 20°C and 30°C

After the chiller is turned on, if water gradually fills up the laser tube and water flows smoothly from the
outlet, the chiller is working properly.

3.1.4.5 Air pump installation(or air compressor)
CMA1309 series use hard pipe structure. To install, connect the outlet of the air pump (or compressor)
to the inlet of the equipment with a pipe, as shown below:
The air pump (or air compressor) is very important in the system. High pressure air is jetted out from light
outlet in the laser head through air pipe. On one hand, this ensures focus lens clean. On the other hand, it plays
the function to prevent from being burning of the material caused by laser. Therefore, during daily maintenance,
users are recommended to keep the air pipe straight free of twist. Otherwise, abnormal blowing may cause
burning of the materials.
After connecting the air channel, connect the patch board with circuit breaker or overcurrent protection.
The input voltage is 220-240V AC, 50/60Hz.

To ensure normal circulation of cooling water in the laser tube, the water circulation
system is equipped with a water protective inducer. In case of unsmooth water flow or
abnormal operation of the water pump, the equipment will automatically enter
protective mode, and the laser tube will emit laser. Therefore, during daily
maintenance, please keep the water pump and water hose clean.
Water cooling laser tube is required to ensure a normal operation of water circulation.
Otherwise, laser tube explosion may be caused.
