INSTALLATION & SERVICE INSTRUCTIONS
690 Series Rotary Sprinkler
Features
• Positive Spring Retraction - Pulls nozzle and cap down out of the
way of people and turf maintenance equipment.
• Three Nozzle Sizes - Multiple nozzle sizes provide 45.1 to 82.2 GPM
flow and produce watering radii from 78 to 108 feet.
• Long Life Gear Drive - Gear drive mechanism is vacuum-packed with
lubricant and isolated from water stream for long, trouble-free life.
• Valve-In-Head Models - Permits head-by-head control to customize
turf watering for various topography and soil conditions. Multi-cycle for
wind or runoff problems, frost control and dew removal without low-head
drainage. Available for hydraulic normally open or 24 Volt electric
systems.
• Sprinkler Operating Mode - Electric valve-in-head models have three
modes of operation; AUTO, ON and OFF. Mode is set using a selector
tool inserted through the sprinkler body flange.
• Built-in Check Valve - Check-o-matic sprinklers utilize a check valve in
the sprinkler base to prevent seepage from low area heads after valve
closure. Check valve will hold up to 35 feet of elevation differential.
• Two-Speed / 60°-120° Models - Provides for more even precipitation.
Runs at half speed in non-overlapping areas.
• Two-Speed / 180° Models - Provides for more even precipitation
where only a selected area is covered by an overlap, such as is found on
greens. Runs at half speed in non-overlapping areas.
• Serviceability - All internal parts of the sprinkler are accessible through
the top of the sprinkler body.
