b)
If ambient temperature is between -10
℃
and 0
℃
, we recommend to use
30% alcohol(volume ratio), and replace it every 2 months.
c)
If ambient temperature is below -10
℃
, the chiller with both heating and
cooling functions must be used, and keep it in full-time operation.
Other requirements:
a)
Before start the device, ensure that the flow and return connections are
correct connected, and confirm that there is no leakage in all the water
circuits. Any abnormal condition in the water circuits may cause a failure
to the operation of the laser.
b)
If the device is not use in a long time, water must be emptied from the
device, and then both the inlet and outlet must be blocked with the caps.
Failure to do so may cause damage to the device.
c)
Pleaseuse compressed gas below 0.5MPa when emptyingwaterfromthe
device. Failure to do so may cause permanent equipment damage to cooling
system.
CAUTION:
Please set the water temperature according to the
requirements above. Setting the temperature too high may cause
an abnormal performance; and liquid water may be condensed
on the laser module or the output head if a too low temperature
is set, which may cause serious damage to the device.
CAUTION: The cooling system should be turned on first. Check
any water leakage and make sure that the water temperature
reaches the set point before start the laser. (25

Installation rule
a)
Place the product in an appropriate position, immobilize it if necessary.
b)
Check if the power supply has the correct voltage (220VAC±10%
，
50/60Hz), and the earth line is connected, make sure it is firm and reliable.
