- After all the air is purged from the system and the sprinkler is operating smoothly, you can start the drive system.
- IMPORTANT: For turbine drives, allow the water to go through
the system for several minutes to carry out any trash or debris that
may have been in the mainline pipe. After the system is thoroughly
flushed, start the drive system.To guarantee the reel will function for an entry pressure
not exceeding 10 bars, take into account the pressure loss of the hose, turbine and
layer change. (fig.38)
