Rain Collector Heater
Installation Manual
The Rain Collector Heater may be
used to protect the Rain Collectors
internal components from freezing
and/or to measure the moisture
content of snowfall. When the
heater is on, it is capable of
melting snow at a rate of 1/4''
(6 mm) of liquid precipitation per
hour. It may not be able to keep up
with larger rates of snowfall.
The rain collector heater warms
only the inside of the rain collector
and the cone itself.
Please note that we have made every attempt to design and manufacture a
safe product, but Davis Instruments assumes no liability for any injury or
damage caused directly or indirectly by the installation or use of this
product.
Note: Although the nominal heater voltage is not hazardous, a short in the wall
transformer could cause hazardous voltage to appear on the heater
wires. For safety, you should always turn the heater’s power unit to the
“OFF” position before removing the rain collector’s cone. We also
recommend that you unplug the wall transformer before removing the
rain collector’s cone.
This instruction manual is designed to take you step-by-step through the
process required to install and use your rain collector heater. Please take the
time to read through this manual before beginning the process.
Note: This heater is not compatible with AeroCone rain collectors. You will need
to replace the AeroCone on your sensor suite, if you have one, with a
classic cone.

Tools and Materials Needed for Installation
In addition to the components listed above, you will need some of the
following tools and materials. Please be sure you have everything you need
before beginning the installation.
Medium Phillips-head and slot-tip screwdrivers
Drill with 5/32” (4 mm) or 3/16” (4.8 mm), and 9/32” (7.2 mm) or 5/
16” (8 mm) drill bits
Wire cutter
Wire stripper or knife
Cable clips or weather-resistant cable ties
Choosing Cable for the Rain Collector Heater
The rain collector heater comes with a 50-foot (15 m) length of 22 gauge
cable. You may extend the length up to 250(80 m) from the power unit to the
AC adapter using 22AWG -16AWG cable with PVC jacket. We recommend
using a 3M Scotchpak or Duraseal heat shrink splice connector when
extending the sensor cables.
Note: If you are using the heater in extreme environmental conditons, the
recommended cable coating may differ .
Use the table below to determine the minimum wire size for the desired lenght
of cable run:
Lenght of Cable Run Minimum Wire Size
Up to 60 feet (18m) 22AWG (0.50mm2)
60 - 100 feet (18 -30 m) 20AWG(0.75mm2)
100 - 160 feet (30 -50 m) 18AWG(1.00mm2)
160 - 250 feet (50 -80 m) 16AWG(1.50mm2)
If the heater cable is routed with any (i.e. any cable running from signal cable
a sensor or SIM), be aware that for cable runs over 50 feet (15 m) the heater
cable’s voltage may interfere with sensor voltages in the signal. To prevent this
interference, do at least one of the following:
Keep the heater cable and the signal cable separated by several inches over
most of the length of the cable run.
Use shielded cable for the heater cable or signal cable (shield must be
grounded).
