Precautions for handling water-cooled heat sinks
Be sure to observe the following precautions and procedures. not safeguarded This can damage the LCOS-SLM and
peripherals.
■
Handling of circulating water
Be careful not to splash the circulating water on this device. When inserting or removing the circulating water
hose, be sure to turn off the power to the device and peripheral devices.
■
Circulating water
Please use soft water (Excluding pure water).
If you use any water other than soft water (antifreeze solution, etc.), please contact our company or our local
representative.
■
Recommended temperature
Since the properties of LCOS-SLM are temperature dependent, it is recommended to use in an environment
where the room temperature is 25 °C and the circulating water temperature is 25 °C. The circulating water
controller (chiller, etc.) can be used to maintain the circulating water temperature at 25 °C, or simply, an
air-cooled circulating water controller such as a CPU cooler can be used in an environment where the room
temperature is 25 °C.
■
Condensation
When circulating water is cooled, condensation is likely to occur if both ambient temperature and ambient
humidity are high. Use the following graph as a reference when operating in an LCOS or in an environment
where the hose does not dew. Since the properties of LCOS-SLM are temperature dependent, it is
recommended to use in an environment where the room temperature is 25 °C and the water temperature is
25 °C as described in the recommended temperature.
■
Circulating Water Controller
For handling of the circulating water and the circulating water controller, follow the instruction manual of each
circulating water controller.
Caution
The WATER connector withstand voltage specification is 0.3 MPa.
Do not exceed the rated value.
