MAINTENANCE
Span Flushing Procedure
3. Remove the pipe drains at each drive unit tower.
Clean sand and foreign particles from these
drains. Turn the rubber drain seal over when
reinstalling. See Figure 89-1.
NOTE
• The rubber drain seals should be turned over
when being reinstalled. This practice helps to
increase the seal life.
4. Remove and clean the sand trap at the last regu-
lar drive unit. See Figure 89-2.
5. Remove plugs from the overhang drains. Clean
sand and foreign particles from these drains.
Turn the rubber drain seal over when reinstall-
ing. See Figure 89-3.
6. Start the pump and allow the machine to flush
thoroughly.
NOTE
• After flushing for winterization, ensure the
water has been allowed to drain completely
before replacing the pipe drains and plugs to
prevent freezing and splitting of the pipeline.
7. Turn off the water supply and re-install the pipe
drains, sand trap and overhang plugs.
