System will not come on at all:
A. Make sure the Mini-Clik
®
 is not installed in the path 
of any watering from the systemʼs sprinklers.
B.  Check to see that the Mini-Clik discs are dry and 
the switch “clicks” on and off freely by pressing the 
top of the spindle.
C.  Look for breaks in the wire leading to the Mini-Clik 
and check all wire connections.
System will not shut off even after heavy rainfall:
A. If a Hunter SRC controller is used, check the dial 
position. If the dial is on the RUN (Bypass Sensor) 
position the controller will disregard sensor. For 
the Pro-C and ICC, make sure the Bypass Switch is 
in "Active."
B.  Check Bypass Switch position. If the switch is on 
the BYPASS position on the controller or external 
by-pass switch (Hunter BPSW) the controller will 
disregard sensor activity.
C.  Check to see if wiring is correct. Check by depress
-
ing the spindle at the top of the cap until the switch 
is heard “clicking” off. When the switch “clicks” 
off, the sprinkler zone should stop immediately.
D. Check the sensitivity setting on 
the Mini-Clik. If the setting is 
set for high rainfall amounts, 
move the cap to a more sensi-
tive setting.
E.  Is rainfall actually hitting the 
Mini-Clik? Check for obstruc-
tions to rainfall such as over-
hangs, tree branches or walls.
FREQUENTLY ASKED 
QUESTIONS
Q: Two days ago it rained and the sprinklers came on 
this morning, how do I get them to stay off longer?
A: There is a “vent ring” located just below the cap 
that can be closed or partially closed to restrict 
airflow through the Mini-Clik. Make sure this ring 
covers the holes on the Mini-Clik, and it will al-
low the discs to dry more slowly, thus keeping the 
Mini-Clik shut off longer. This adjustment can com
-
pensate for an “overly sunny” installation location.
Q: How much water and money can be saved?
A: The amount saved varies, but in a temperate climate 
with average rainfall, savings are usually substan-
tial. There are several factors involved in determin-
ing how much a Mini-Clik can reduce water usage: 
how often it rains, whether or not the controller is 
left on for automatic operation, and the amount of 
water applied by the system per cycle.
  Basically, if you know the water costs in your area 
and how much water is being applied per watering 
cycle by the whole system, then you will know how 
much is being saved each time the Mini-Clik inter-
rupts the sprinkling cycle because of rainfall.
  As an example, take a system that irrigates 15,000 
square feet of turf and is set to run each zone so 
that the equivalent of ¼" of water is applied per 
cycle. Volumetric calculations determine that 2337 
gallons of water are being applied over the 15,000 
square feet of turf per cycle. Using an average water 
cost table for the San Marcos, California area, it 
costs $3.47/thousand gallons (or, for our example, 
$8.11 for the 2337 gallons). Therefore, every time 
the Mini-Clik prevents the sprinkling cycle from 
proceeding because of rainfall, $8.11 is saved, and 
2337 gallons of fresh water are not wasted. Multiply 
this by the number of substantial rainfalls that occur 
in your area over one growing season and you can 
see the potential for savings of money and water. 
The Mini-Clik pays for itself in a short time, and 
the installed irrigation system is the most efficient it 
can be.
