Coolant specification
Coolant specification
The quality of the coolant used can have a major impact on the efficiency and service
life of the cooling circuit. The recommendations listed below are useful for servicing
a good cooling circuit with anti-freeze and/or anti-corrosion.
Z
Always use clean, soft water.
DANGER!
Anti-freeze is poisonous
X
Anti-freeze contains ethylene glycol and other components which can result in
poisoning if ingested.
X
Ingression into the human body can also result if poisonous quantities come into
contact with the skin for long or repeated periods.
X
Note the manufacturer’s safety instructions.
NOTE
Anti-freeze/water mixture ratio:
X
1: 1 (anti-freeze to -35°C)
X
Never mix different types of anti-freeze.
NOTE
Corrosion damage
X
Even if the coolant cannot freeze up due to the application conditions, you must still
use anti-freeze. The anti-freeze provides protection against corrosion and raises
the boiling point of the coolant.
The quality of the anti-freeze must be checked at least annually, e.g. at the start of
the cold season.
If the correct procedures are not applied, the manufacturer cannot be held liable for
frost or corrosion damage.
