12-2 INFORMATION ON COOLING WATER
FOR THE CIRCULATING WATER COOLER
•
Regarding handling cooling water and circulating water cooler, please refer to instruction
manual attached to the circulating water cooler.
•
It is recommended to use soft water (except deionized water) for cooling water.
•
Do not use hard water for cooling. It cause inside of cooling water circulating path to be
calcified or corroded and it result lower flow rate or water flow stop. When using hard water,
please conduct a process to soften water before use it.
12-2-1 WHEN USING COOLING WATER OTHER THAN RECOMMENDED
Note
Pure water
•
Deionized water is not appropriate for cooling water. There is possibility that deionized water
absorb component of cooling water path and it may cause corrosion. In addition deionized
water is easy to be polluted and cause impurity, sliminess or forming foreign substances. It
cause lower flow rate or water flow stop.
Note
Distilled water / Deionized water
•
When using the camera inside clean room, it is possible to use distilled water or deionized
water by conducting periodical check. However please notice it increases possibility of
corrosion inside cooling water path, lowering flow rate or water flow stop.
•
Monthly check : Check water impurity, non-existence of sliminess, foreign particle is
not mixed with water or not adhered inside water path and no unusual
odor. If you find any of the issues, please exchange cooling water and
clean cooling water path.
Note
Soft water from tap
•
It is possible to use soft water from tap with conducting periodical change of cooling water
and check up. However please notice it increases possibility of corrosion inside cooling
water path, lowering flow rate or water flow stop.
•
Monthly check : Check water impurity, non-existence of sliminess, foreign particle is
not mixed with water or not adhered inside water path and no unusual
odor. If you find any of the issues, please exchange cooling water and
clean cooling water path.
•
Exchange cooling water every 3 months.
•
Clean cooling water path every 6 months.
Note
Bottled water
•
One example of soft water which is commonly available is mineral water (Hardness less
than 70). Please check hardness of water by referring product information of bottled water
manufacturer.
