4. Assembly
 Threaded connection on the sprinkler is 2½" female thread.
 For sealing the thread, hemp and a jointing compound has to be used e.g. Fermit special
 To screw on the sprinkler, always use a pipe wrench size 2½".

Grub screw
Lock nut
Rev. 26.11.2015
Screw on the connection socket up to the
detent, so that the sprinkler cannot unscrew
itself during operation.
The impact lever has to deflect approx.
60 degrees. The angle of deflection can be
regulated at the stop screw, after the
hexagon nut has been loosened. The marking
is on the inside of the screw (bolt). If the
sprinkler is equipped with nozzles that have a
smaller diameter, or if the operating
pressure is somewhat lower, then the impact
lever will have a smaller angle of deflection.
Larger deflection = turn the screw in the
direction +.
If bigger nozzles are used, or if the pressure is
high, the angle of deflection will be larger.
Less deflection = turn the screw in the
direction ‐.
The braking effect can be set, after the both
lock nuts have been loosened.
More braking effect, tighten the grub
screw. Less braking effect, loosen the grub
screw.
The braking effect should be such that the
sprinkler does not turn backwards, during
rotation of the impact lever.
Loosen or tighten both grub screws in the
same way.
