▪ Always carry out maintenance tasks outside the operating space.
▪ Only perform maintenance work which is described in these installation and operating in-
structions.
▪ Use only original parts from the manufacturer for maintenance and repairs. The use of parts
other than original parts absolves the manufacturer of any liability.
▪ Collect any drips of fluid and operating fluid immediately and dispose of it according to the
locally applicable guidelines.
Change of operating fluid
In the event of a motor defect, a pressure of several bar can build up in the sealing cham-
ber! This pressure escapes when opening the screw plugs. Screw plugs opened carelessly
can be ejected at high speed! To avoid injuries, observe the following instructions:
▪ Adhere to the prescribed sequence of work steps.
▪ Unscrew screw plugs slowly but never fully. As soon as the pressure escapes (an audible
whistling or hissing of air), do not turn any further.
WARNING! When the pressure escapes, hot operating fluid can also be ejected. This can
result in scalding! To avoid injury, allow the motor to cool down to ambient temperature
before commencing work!
▪ When the pressure has fully dissipated, fully unscrew screw plug.
The seal housing is filled with white oil. Replace the operating fluid during regular mainte-
nance work and dispose of it according to the local guidelines.
▪ Provide the installation and operating instructions in a language the personnel can under-
stand.
▪ Ensure the required training of personnel for the specified work.
▪ Provide the required protective equipment and ensure that the personnel wear the protec-
tive equipment.
▪ Ensure that the attached safety and information signs on the product are always legible.
▪ Instruct the personnel in the operating principle of the system.
▪ Exclude any potential risks presented by electricity.
▪ Secure and demarcate the work area.
▪ For a safe workflow define the personnel's work plan.
▪ When the product works in normal operation mode, carry out a sound pressure measure-
ment. If the measured sound pressure is more than 85 dB(A), wear hearing protection and
include such an instruction in the work regulations!
