ables and ngs inside the
pump enclosure, refer to Inspect the connecons, pipelines, cables and
ngs on page 67.
B. Examine and clean the exhaust pipe, elbow, and check valve.
Note:
The sys

Make sure that seals are always replaced with the same type.
The system requires no maintenance. Pump protecon sensors installed in the system
do not require roune maintenance. The decommissioning operaons that can be
carried out, refer to Relocate the system for decommissioning on page 86 and Drain the
cooling water for decommissioning on page 87. Maintenance must be carried out by our
service centres refer to Service on page 91. The frequency of maintenance operaons
depends on the process.
