Requirements on Cooling Water:Purified water should be used.
a) In order to prevent the growth of mould that may lead to blockage, adding
alcohol solution to about 10% of the total volume is recommended.

Wuhan Raycus Fiber Laser Technologies Co., Ltd.
User Guide of RFL-P500H
10
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±0.5℃)
3.3 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.

c) Connect the power cable and control cable to the product when power
supply is OFF.
d) Clamp the water pipes ontopipe connector, run the chiller to check if there
is any leakage in the water circulation.
e) Check the output head and clean it before installation. This procedure must
be performed by Raycus personnel or person authorized by Raycus.
f) Prevent the delivery cable from treading, pinching or excessive bending
during installation.
g) Make sure the environment is clean, or the output head may be
CAUTION: All the cables can only be connected when power
supply is off. Hot plug may damage the device.
CAUTION:
(1) Ensure that there are no fiber bends in radius less than 30cm
when the product is installed. Avoid excessive twisting and
tight bends during the robotic arm movements.
(2) Tight bends will damage the laser delivery system.
CAUTION:
(3) Keep the protective cap properly, prevent it from
contamination; Or the aperture will be contaminated when
capped.
(4) Make sure the aperture and the cavity of the processing head is
