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. For some weather conditions, it may be necessary to add a lamp or
heater beneath the unit to keep the drains open.
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.
CAUTION:
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 pro-
cess required to install and use your Rain Collector Heater. Please take the time
to read through this manual before beginning the process.
