Recommended Installation Procedures
The INF55 sprinkler is designed specifically
for turf areas requiring _____ coverage.
These products offer the most economical
method of irrigation where flows and system
pressures are available to support a greater
radius.
The INF55 sprinkler should be specified
for installation on a Toro swing joint. The
swing joint should be specified as a triple-
swing type, allowing movement up, down,
laterally and at an angle-to-grade. The
sprinkler should be installed with the body
cover at grade.
Individual sprinkler head control is
accomplished using a single INF55 valve-in-
head sprinkler per controller station. Use of
the valve-in-head model will allow individual
station control, and is particularly useful for
irrigating distinct turf regions at unique
application rates.
INF55 sprinklers are engineered to provide
a smooth, consistent curtain of water across
the arc, with provision made for head-to-
head coverage. For proper spacing, ensure
that system design and installation accounts
for prevailing wind conditions and body
cover angle-to-grade.
It is recommended that sprinklers are
installed 2” (5cm) from hardscaping and 6”-
12” (15,2-30,5cm) from buildings or other
vertical impediments to allow for normal
maintenance procedures and to minimize
overspray on buildings. Where possible,
sprinkler heads should be installed in a
manner that will minimize nozzle stream
contact with trees, controller enclosures,
shrubbery or other obstructions.
