Note on antifreeze mixed liquid
Precautions in handling the antifreeze liquid
• When only water is supplied to the cooling water
tank without antifreeze liquid, the water heating
unit or head may be damaged due to freezing.
• When only antifreeze liquid is supplied to the
cooling water tank without water, the machine
does not work properly, and may cause an error.
• If water in the cooling water tank frequently
becomes insufficient, contact a distributor in your
district or our office.
• Dispose of the waste water mixed with antifreeze
liquid pursuant to the regulations of your district.
To make mixed liquid, be sure to use the potable
water meeting one of the following conditions:
• Calcium content:
1 mg/100 ml (10 mg/L) or less
• Hardness : 60 mg/L or less
• Distilled water (Purified water)
• Water and antifreeze liquid compound ratio should
be 2(water) to 1(Antifreeze liquid).
Or use our specialized antifreeze mixed liquid
(SPC-0783).
• Use it within one week when you make mixed
liquid. The mixed liquid that one week or more
passed after it makes it is never used for this
machine regardless of use/unused.
Moreover, do not add to the mixed liquid newly
made.
• Be sure to wear goggle and gloves for handling
the antifreeze liquid.
• Use the recommended antifreeze liquid(SPC-
0394) by Mimaki. If not, the cooling device may be
broken. (Supplied antifreeze liquid :1000cc x 2
bottles)
• Do not touch the antifreeze liquid directly. If the
antifreeze liquid settles on your skin or clothes,
immediately wash it off with soap and water. If you
get antifreeze liquid in your eyes, immediately
wash your eyes with a lot of clean water. Then,
consult a doctor as soon as possible.
• Store antifreeze liquid in a dark and cold place.
• Store antifreeze liquid in a place that is out of the
reach of children.
• When discarding antifreeze liquid which is no
longer needed, entrust them to an industrial waste
disposal contractor, clarifying their contents.
• Before using antifreeze liquid, be sure to read the
Material Safety Data Sheet (SDS).
• Prepare a tank with a cap to put in the waste water
from cooling water tank.
• When water in the cooling water tank is low, a
warning message “WATER LACK” is displayed. In
this case, refill antifreeze water in the way shown
as the next page.
