Mounting
Standard Mount: Us-
ing the screws provided, 
mount the Rain-Clik™ 
on any surface where it 
will be exposed to unob-
structed rainfall, but not 
in the path of sprinkler 
spray. The switch-housing 
portion must be upright, 
but the swivel-bracket can 
be moved for mounting on 
any angled surface.
Gutter Mount: (SGM Sold 
Separately): The gutter 
mount can be purchased 
as an optional accessory 
for your Rain-Clik (order 
p/n SGM). The SGM al-
lows the Rain-Clik to be 
mounted directly to the 
side of a gutter. To install 
your Rain-Clik on a gutter, 
Remove the screw, nut and 
standard mount supplied 
with the Rain-Clik, and 
reinstall the gutter mount. Position the gutter mount 
on the edge of the gutter and twist the thumbscrew to 
secure it in place.
Helpful Hints for Mounting:
A. When looking for a suitable location such as on the 
side of a building or post, the closer the Rain-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 
Rain-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.
C.  As described in the “Operation” section of this man
-
ual, “reset rate” refers to the amount of time it takes 
the Rain-Clik to dry out sufficiently for the sprinkler 
system to be allowed to come back on. The mount
-
ing location will affect this rate and should be taken 
into consideration should extreme conditions exist. 
For example, mounting the Rain-Clik on a very 
sunny, southern end of a building may cause the 
Rain-Clik to dry out sooner than desired. Similarly, 
mounting on the northern end of a building with 
constant shade may keep the Rain-Clik from drying 
soon enough.
Once the Rain-Clik is mounted, run the wire to the 
controller, and fasten it every few feet with wire clips 
or staples for best results. If an extension to the wire 
provided is needed, use the following table to deter-
mine the minimum wire gauge needed:
If the extension needed is:
25-50 feet  use:  20 gauge
50-100 feet  use:  18 gauge
100 feet or more  use:  16 gauge
Wiring To Your Irrigation System
For the Rain-Clik: WARNING! This unit is designed to 
be installed in conjunction with 24VAC circuits only. 
Do not use with 110 or 220VAC circuits. All wiring 
must conform to National Electrical Code or applicable 
local codes.
Wiring to the Hunter SRC
The Rain-Clik connects directly to the SRC. This 
allows you to easily override the sensor by using the 
RUN (BYPASS SENSOR) position on the dial.
1.  Route the wires from the Rain-Clik up through the 
same opening used for valve wiring.
2.  Connect one wire to the RS terminal and other to 
the C terminal (See Fig. 1).
