Danger of injury caused by spray water
The coolant is harmful to eyes and skin and can damage surfaces.
If the air escapes intermittently, coolant spray can reach your skin or eyes.
Therefore, wear appropriate protective clothing for all work on the converter. However, if your
eyes or skin do come into contact with coolant, rinse the affected area thoroughly with tap
water as soon as possible. If coolant has escaped, remove the liquid from the affected
surfaces.
Please refer to the EU safety data sheet of the coolant manufacturer.
