Installation Instructions - Hunter Rain-Clik Product Information

enabling the valve to continue to irrigate for its
prescribed time.
Post 6:20 AM – For the balance of the day (provided
that Zone 3 is not scheduled to operate again), flow
is monitored by the Flow-Clik™ without exceed-
ing the maximum and the total irrigation schedule
is completed.
High Flow Scenario 2 - Mainline Ruptures
If a mainline ruptures, the Flow-Clik would identify a
"high-flow" condition approximately 20 seconds after
the first valve is activated based on the irrigation sched-
ule and the master valve would be shut down. Flow
would continue to be monitored every 10 minutes and
after a 20 second delay a "high-flow" condition would
be identified keeping the system shut down until the
mainline pipe is repaired.
In both of these scenarios, the "high-flow" shut
down capability of Flow-Clik sensor would eliminate
the water waste and associated damage to the site that
would be caused by the lateral line break, while still
allowing the rest of the irrigation system to operate.
INSTALLATION
INSTRUCTIONS
Installing the Flow-Clik Sensor Body
The Flow-Clik sensor body (FCT series) is designed in
diameters from 1" to 4". It is installed into the mainline
or lateral pipe of the irrigation system. It is important
to install the Flow-Clik Sensor Body downstream of
the master valve (for mainline installations) or the zone
valve (for lateral line installations). Also, it is necessary
to install the Sensor Body in an area of low turbulence
within the system. Areas of high turbulence will cause
erratic readings from the Flow-Clik.
The following figure represents a recommended
sensor body installation. There must be at least 10
times the pipe diameter of straight pipe upstream of
the Sensor Body inlet and at least 5 times the pipe
diameter in length of straight pipe downstream of the
Sensor Body outlet. This will assure that the Flow-Clik
sensor be placed in the optimum position within the
irrigation system.

Note:
For maximum protection against overflow conditio-
ns, it is required that a master valve be installed.

Installing The Flow-Clik Sensor Into
The Sensor Body
The Flow-Clik Sensor Body comes with a plug that
allows for installation of the Sensor Body into the irri-
gation system prior to installing the Sensor. This allows
the sensor body to be installed separate of the sensor
and prevents damage to the sensor during installation
of the body.
Note: Do not attempt to remove the
sensor plug or sensor while the
system is under pressure.
To install the sensor into the body:
1. Turn the system pressure off.
2. Unscrew the cap from the top of
the body (Fig. 1).
3. Use pliers or a screwdriver and
carefully pry the plug from the
body.
4. Insert the sensor into the sen-
sor body (Check to make sure
the two o-rings provided with
the sensor are installed in the
grooves at the lower end of the
sensor). The sensor has a flat
side that engages with a flat on
the inside of the sensor body
(Fig. 2).
5. Replace the cap on the sensor
body (hand tighten only).
6. Feed the two sensor wires through the hole in the
cover and snap the cover on the cap.
Mounting the Flow-Clik Interface Box
The Flow-Clik Interface Box is designed to mount
next to the irrigation controller. A door is provided to
keep water and debris from entering the inside of the
Sensor
