Rain Collector Heater
Installation Manual
The Rain Collector Heater may be
used to protect the Rain Collector’s
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.
