18.4 Filling the coolant system
A number of protective measures must be observed and taken in order to ensure that the handling of
coolant does not cause health risks or environmental loads.
■ Always observe the datasheet and the safety regulations of the coolant being used (can be
obtained from the supplier or manufacturer)
■ Observe all safety regulations set out in these operating instructions, in particular those that refer
to the safe handling of coolants.
