Correct Installation
ARC ADJUSTMENT
All I-40-36S-ON heads are 360˚ ONLY. There
is no arc adjustment. For less than 360˚ use
I-40-ADS.
RADIUS ADJUSTMENT
Insert the hex end of the Hunter wrench into the
nozzle-retainer/range-adjustment screw (Fig. 1).
Turn the screw clockwise into the stream of water
to decrease the radius, or counter-clockwise to
increase the radius.
PRECIPITATION RATE ADJUSTMENT
Where excessively wet or dry areas are a
problem, the precipitation rate may be adjusted.
Simply replace the existing nozzle with a larger
one to increase, or a smaller one to decrease the
rate of precipitation.
NOZZLE INSTALLATION
1. Insert the key end of the Hunter wrench into
the lifting socket of a pop-up sprinkler. Pull the
riser up to gain access to the nozzle socket.
2. Using the Hunter wrench, loosen the nozzle-
retainer/range-adjustment screw. If a nozzle is
already installed in the sprinkler, it may now be
removed by briey turning on the water.
3. Discard nozzle if removed with pliers.
Slip the desired nozzle into the nozzle socket.
Note that the socket is angled up 25˚ (see
Fig. 2). Tighten the nozzle-retainer/range-
adjustment screw.
4. Install like opposing nozzles.
