12-2-1 WHEN USING COOLING WATER OTHER THAN RECOMMENDED
Pure water
Note
•
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.
Distilled water / Deionized water
Note
•
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
Soft water from tap
Note
•
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
• Exchange cooling water every 3 months.
• Clean cooling water path every 6 months.
Bottled water
Note
•
One example of soft water which is commonly available is mineral water (Hardness less
