NOTICE
Corrosion due to insufficient cooling water quality
The materials used in the cooler are selected to match the cooling water quality for which the
air-water cooler was ordered. The cooler cannot be simply used without taking any other
measures if other water conditions apply. If the cooling water quality is unsuitable, the air-to-
water heat exchanger may suffer corrosion and fail.
● The chemical composition of the cooling water must comply with the configuration
specifications.
● If the cooling water quality fails to satisfy the quality stated on the order, please contact the
Service Center.
● Please observe the recommended water quality in the operating instructions for the air-
water cooler.
NOTICE
Overheating of the machine as a result of additives in the cooling water
Additives for antifreeze or corrosion protection can have a negative impact on the heat
transporting properties. The machine can overheat.
● Only operate the machine with the contractually agreed cooling water quality.
