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.

filling Irrigation lateral line Piping
With the water supply valve (main isolation or ball valve prior to control
valve) opened only enough fill the piping slowly, activate the manual
ON bleed feature located on the control valve. Fill lateral piping until
all the air has been relieved and there is a constant flow of water. Once
the air has been removed from all lateral piping, turn the water supply
valves to the full-open position.
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.
