● Make sure that the balancing method of the output element is correct!
● If the power output element is shorter than the feather key with balancing type "H", then
● Power output elements may only be pushed on or pulled off with the correct equipment.
5.6 Cooling water quality
The chemical composition of the cooling water must comply with the configuration
specifications.
The materials used in the heat exchanger are chosen to suit the water conditions for which
the heat exchanger has been ordered. The exchanger cannot necessarily be used under
different water conditions. Refer to the dimension drawing text for the fouling factor.
In the case of a heat exchanger built for chemical purification (closed cooling-water circuit),
the water quality must comply with the recommendations made by the manufacturer.
Refer to the operating instructions of the air-to-water heat exchanger, section headed
"Supplementary operating instructions". [ID 1014.01]

you must machine off the section of feather key protruding from the shaft contour and
output element in order to maintain the balance quality.
WARNING
The feather key can fall out
The featherkeys are only secured during transport to prevent them from falling out. If a
machine with two shaft extensions does not have an output element on one shaft
extension, the feather key can fall out during operation.
Death or serious injury can result.
On shaft extensions without output element, make sure that the feather key cannot fall
out and shorten it by approximately half for balance type "H".
