12-2 WHEN USING AT WATER-COOLING
(1) Circulating water cooler
•
Regarding handling cooling water and circulating water cooler, refer to instruction manual
attached to the circulating water cooler.
(2) Cooling water
•
It is recommended to use soft water (except pure 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, conduct a process to soften water before use it.
When using cooling water other than recommended;
[Pure water]
•
Pure water is not appropriate for cooling water. There is possibility that pure water absorb
component of cooling water path and it may cause corrosion. In addition pure water is easy to
be polluted and cause impurity, sliminess or forming foreign substances. It cause lower flow
rate or water flow stop.
[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.
[Soft water from tap]
•
It is possible to use soft water from tap with conducting periodical change of cooling water and
checkup. 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.
[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.
