training manual. Answers to the question can be found
on page 37.
1. Hunter markets weather sensors and ____ sensors.
2. Which Hunter rain sensor shuts the system off within a
few minutes of a downpour?_________
This trademarked feature is called _________™.
3. The calibrated vent ring located on the Rain-Clik™ can
be adjusted to control the time it takes to dry out the
hygroscopic discs, which in turn will keep the system
from operating for a minimum of _____ to a maximum
of _____ after the rain stops falling.
4. The Rain-Clik and Mini-Clik
__ feet of attached control wire providing for fast and
efficient installation. To extend the total distance of the
sensor from the controller to 105 feet, a minimum of __
gauge wire can be attached to the integral wire utilizing
waterproof connections.
5. Hunter rain and wind sensors cannot be wired in series to
provide the ability to shut down an irrigation system due
to excessive rain or wind.
True or False
6. The Wireless Rain-Clik™ provides for quick, effortless
installation on retrofit sites as well as problematic sites
in which it is difficult to run wire from the controller to
the sensor installation. The Wireless Rain-Clik can be
installed up to ___ feet from the controller.
7. The Mini-Clik has ____ adjustment settings. An irriga-
tion system will be shut down once the device has col-
lected a set amount of irrigation based on the setting. The
settings provide a range of ___ inch to __ inch
8. Hunter offers a version of the Mini-Clik that can be
attached to ½" conduit for markets that require all wires
to be placed in a conduit. The model is a ____________.
9. Hunter Mini-Clik and Rain-Clik Sensors utilize _____
_______ discs that expand proportionately relative to
the amount of rainfall that the sensor device collects. As
these discs absorb water they expand in height reaching
a set point in which an integral ____________ in the
device is held open to interrupt the circuit and disable the
controller from irrigating. After the rain stops, the disks
shrink in size releasing the ____________, allowing the
controller to irrigate during its next programmed cycle.
10. Hunter controllers incorporate an integral ____________
switch which enables the irrigation system to operate
independent of sensor control.
11. For controllers that do not have a built in sensor bypass,
a Hunter Model _____ can be utilized by interrupting the
valve ________ wire.
36
rain sensors come with
®
12. With a Hunter Wind-Clik
®
irrigation system will shut down when the wind speed is
between __ and __ miles per hour.
13. The Hunter ____________ automatically shuts down
the irrigation system when the temperature drops below
freezing (32˚F) and allows the system to start operating
again when the temperature reaches approximately 37˚F.
14. A Hunter Freeze-Clik sensor can be disabled by utiliz-
®
ing the manual bypass switch on the controller. True or
False
15. The mini weather station that incorporates a rain sensor,
wind sensor and a freeze sensor in one unit is a Hunter
________ model.
16. The Hunter Flow-Clik™ is an _________, _____, and __
______ flow monitoring system that shuts down a system
or valve when flow through the device has __________
a pre-set amount minimizing water waste and potential
liability due to erosion caused by excessive runoff.
17. A Flow-Clik Sensor ______________ is wired into the
controller terminal strip providing LED displays which
identify specific flow conditions. A ____ light indicates
that the irrigation system is shut down due to an overflow
condition that occurred. A ____ light indicates an accept-
able amount of water is flowing.
18. A Flow-Clik can be installed up to a maximum of _____
feet provided __ gauge wire is used.
19. Increased start-up flow velocities won't effect flow sensor
readings as the user can program a start up delay of
______ to ______ seconds by simply turning a dial to a
set position on the Sensor Interface box.
20. The unit is easy to calibrate as the user simply pushes a
button on the interface box while the _________ flow
valve is operating.
21. The flow range for a 1½" inch Flow-Clik
is from ____ to ____ GPM.
22. When installing a Flow-Clik™ it is important to allow
for a straight pipe run into the device of at least __ times
the pipe diameter and on the outlet side at least __ times
the pipe diameter.
