5.2.11 Checking the cooling coil for deposits (Option: CC)
The cooling water flow rate must be controlled. For this, pay attention to the information in Section 4.7
"Cooling coil (Option: CC)".
If a chemical cleaner is used, it must be ensured that the cleaning agent does not attack the material
of the cooling coil (copper pipe and brass fittings).
Check the cooling coil and the cover for leaks if strong corrosion is found on the connections.
Please contact the NORD Service department.
5.2.12 Cleaning or replacing the vent
5.2.12.1 Vent filter (Option: FV)
The ventilation filter uses a wire mesh as the filter material and enables an equalisation of pressure
between the interior of the gear unit and the environment. Visually check the ventilation filter for
soiling. A soiled filter is no longer capable of fulfilling its function and must be replaced.
1. Unscrew the old ventilation filter.
2. Screw in the new ventilation filter with a new sealing ring (see chapter 7.4 "Screw tightening
torques").
