PGP Installation:
The PGP
®
pop-up sprinkler should be installed
at finished grade as shown in the illustration
(Fig. 1).
Arc Adjustments:
Adjustable heads are preset to approximately
180˚. Sprinklers may be adjusted with water
on or off. It is recommended that initial adjust-
ments be made before installation.
1. Using the palm of your hand, rotate the
nozzle turret counterclockwise to the left
stop to complete any interrupted rotation
cycle (Fig. 2).
2. Rotate the nozzle turret clockwise to the
right stop. This is the fixed side of the arc.
The nozzle turret must be held in this posi-
tion for arc adjustments.
The right stop does not change.
To Increase the Arc:
1. Insert the
plastic key
end of the
Hunter
wrench into
the adjust-
ment socket (Fig. 3 & 4).
2. While holding the nozzle turret at the right
stop, turn the wrench clockwise. Each full
360˚ turn of the wrench will increase the
arc 90˚.
3. Adjust to any arc between 40˚ and 360˚
(Fig. 5).
