Filling Irrigation Mainline Piping; Control Valve Flow Adjustment - Hunter STK-1 Instrucciones De Instalación

provide a means to securely attach the synthetic "carpet" around
the perimeter of the enclosure. Depending on Synthetic Turf Field
contractor, the carpet will be attached with tack nails or glued or both.
The most common tack/glue board construction material is Trex™
type 2" x 4" lumber. Depending on the field design and the
location of the enclosure, the tack board will be an independent
perimeter board or, attached to the field perimeter tack/glue board
as shown below.
The tack/glue board rests upon the compacted field base material.
The design can be a very close-fitting frame about the enclosure's
exposed upper rim with adhesive between the frame and the
enclosure or, a looser framework with concrete between the frame
and enclosure as shown below. The tack/glue board elevation is
often equal to the field perimeter tack/glue board. Or, it may be
equal to the elevation of the enclosure's perimeter rim. Or, it may
vary depending on the material (if any) that will be glued to the top
of the enclosure's cover (field carpet, track surface, etc.). Refer to the
field and irrigation specifications to determine appropriate level.

filling Irrigation Mainline Piping

When filling the irrigation mainlines with water, do not do so
through the rotor. Instead, attach a quick coupler key to the quick
coupler that is farthest from the mainline source. Open water
supply valve only enough to fill the mainline slowly. Run the system
discharging through the quick coupler until all air is relieved from
the mainline.

Control Valve flow adjustment

Sometimes the flow and pressure characteristics of the system cause
the control valve to close too slowly. The Hunter ICV control valve
comes from the factory with the flow control stem turned down a
couple of turns to help prevent slow closing. If your control valves
are closing too slowly, adjust the flow control as follows:
Activate the rotor by using the controller's manual feature or by
using Hunter's hand-held "Roam" remote control (do not activate
using the manual bleed feature on the valve). Allow the pressure
and flow to come up and stabilize. Once stabilized, turn the flow
control knob ½ turn clockwise. The flow control knob is located on
top of the valve in the center. The first ½ turn clockwise may be
tight if the system is not stabilized. After the knob has been turned,
wait approximately 5 seconds for the pressure to stabilize again.
This waiting period makes it easier to turn the knob. Continue
turning the knob using this turn-and-pause method until the rotor's
water stream starts to be affected by the flow restriction (reduced
radius). Now turn the knob ½ turn counter-clockwise. This will be
the optimum flow control setting.
