Installation
The installation process of this model is similar to that of the regular model
(see
pages 10-19
).
Screwing and tightening of the sprinkler can be done by hand. The use of a 20 mm
spanner is not necessary.
Adding a PRV (pressure regulating valve)
Install a PRV at the sprinkler inlet when a 100% flow rate and
distribution uniformity is required.
The presented model is suitable for an exit pressure of 2.5 bar.
For other exit pressure values, contact your local Netafim™
representative.
Installation
The installation process of the sprinkler and PRV is similar to that
of installation on solid set riser pipes (see
page 12
).
Screwing and tightening of the PRV should be done by hand.
ATTENTION
Make sure the PRV is connected to the sprinkler
with the arrow pointing towards the sprinkler (up).
NOTE
The PRV bottom thread is ¾" female. To connect the PRV to
a riser with a thread that is not ¾" male, use an apropriate
adapter/reducer from the vast selection offered by Netafim™
(see
page 26
and at
XXX
).
