WARNING
Explosion hazard
If the anti-condensation heating is switched on directly after the machine is switched off, the
temperature class or the maximum surface temperature of the machine can be exceeded.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
Do not switch on the anti-condensation heating for at least one hour after the motor has been
switched off.
8.6.2
Avoidance of frost and corrosion damage in the cooling system
● For avoidance of frost and corrosion damage, completely drain the water from the cooling
system. Then blow air through the cooling system to dry it.
If the cooling system cannot be drained because standby capability is required at short
notice, protect the cooling circuit against frost and corrosion damage. To do this, add
suitable additives to the cooling water.
NOTICE
Impairment of the heat transport
Additives such as anti-freeze and corrosive inhibitor can impair the heat transport.
Operate the motor only with the contractually agreed water quality.
For avoidance of deposits, the cooling water circuit must then be kept running. So as to be
certain of excluding the possibility of formation of condensation within the machine, the anti-
condensation heating should also remain switched on (if fitted).
8.6.3
Avoidance of damage to roller bearings during stoppages
Extended stoppages at the identical or almost identical resting position of the roller bearings
can lead to damage such as brinelling or formation of corrosion.
● During stoppages, regularly start the machine up for a brief period once a month, or at least
turn the rotor over several times.
If you have uncoupled the machine from the driven machine and secured the rotor with a
rotor shipping brace, then remove this before turning the rotor over or starting the machine
up.
Make sure that the resting position of the roller bearings after the rotor has been turned
over is different from what it previously had been. Use the fitted key or the coupling halves
as reference markers.
● During re-commissioning, refer to the information in the "Commissioning" section.
