Includes 25 Feet of 20 Gauge Two 
Conductor Wire…
Fast and easy mounting out of sight
Hunter supplies wire needed for installation within 
25 feet of the controller. Whether you pre-install on a 
pole or install at the job, with 25 feet of wire already 
attached to the Mini-Clik
®
, installation is fast and 
easy. When contractors go out to the job site with the 
Mini-Clik, they donʼt have to worry about forgetting 
the wire! If longer wire runs are needed for installation, 
no problem! Just add an extension.
If the extension needed is:
25-50 feet  use:  20 gauge
50-100 feet  use:  18 gauge
100 feet or more  use:  16 gauge
INSTALLATION 
INSTRUCTIONS
In most installations, the Mini-Clik acts as a switch to 
break the electrial circuit to the solenoid valves of the 
irrigation system when it has rained. This allows the 
timer to advance as scheduled, but keeps the valves 
from opening the water flow. Once the Mini-Clik has 
dried sufficiently, the switch closes again to allow for 
normal operation.
For the Model Mini-Clik-C: This rain sensor unit 
is the same as the standard model except for the lack 
of an aluminum mounting bracket and the addition of 
a ½" threaded cap, which allows for the easy use of 
electrical conduit to totally enclose the wires. Unless 
local code states otherwise, plumbing grade PVC pipe 
can be used as well as electrical grade conduit.
For the Model Mini-Clik-HV: This rain sensor unit is 
designed to be used with automatic irrigation systems 
of two principle designs: 1) single-station electrical 
timer (e.g., Intermatic) that switches power to a pump, 
either directly or through a relay; or 2) single-station 
electrical timer that switches power to a solenoid valve. 
Mounting
Standard Model: Using the screws provided, mount 
the Mini-Clik on any surface where it will be exposed 
to unobstructed rainfall, but not in the path of sprinkler 
spray. The switch-housing portion must be upright (as 
pictured), but the 
swivel-bracket can 
be moved for mount-
ing on any angled 
surface. Loosen the 
locknut and screw 
before swiveling 
bracket, and then re-
tighten.
For the Conduit 
Model Mini-Clik-C: 
The conduit acts 
as the mounting 
support for the unit. 
Therefore, place and 
mount the conduit to 
allow for the desired 
sensor location as 
described in the main instructions for the standard 
model. Be sure to support the conduit sufficiently along 
its various lengths.
For the High-Voltage Model Mini-Clik-HV: The 
mounting of this unit is primarily made by screw-
ing the fitting end into the threaded holes of covers 
to rectangular junction boxes (for outdoor use) or the 
covers of round junction boxes commonly used for 
outdoor spotlights. Locate the junction box so that with 
the Mini-Clik attached, unobstructed rainfall will hit 
the outermost sensing end of the unit. If a longer reach 
is needed, the “Carlon” flexible conduit piece can be 
substituted with a slightly longer piece (up to 8" length 
with no support or up to 11" with support).
Helpful hints for mounting:
A. When looking for a suitable location such as on the 
side of a building or post, the closer the Mini-Clik 
is to the controller, the shorter the wire run will be. 
This will also minimize the chance for wire breaks.
B.  The ideal location for mounting is not always the 
most practical location. In the case where a compro-
mise must exist (such as low location on a side wall 
rather than the preferred high location), note that the 
Mini-Clik will still work as it will always receive 
some rainfall – it just will not be as accurate in its 
gauging as it could be.
