Selecting a Mounting Location for the DS-7C
The small corded device with the interleaved grid is the remote precipitation or "moisture" sensor. The
brass cylinder protruding from the bottom of the DS-7C enclosure is the temperature sensor. For reliable
rain and snow detection the moisture sensor must be exposed to a clear view of the sky. For proper
temperature detection the DS-7C enclosure must be mounted outdoors, away from furnace vents, dryer
vents, and other sources of heat. Operating temperature range is -40
°C to +85°C.
When powered, the
DS-7C moisture grid will always remain hot. This is normal. This allows the sensor to continuously
melt/evaporate rain and snow from the grid.
The DS-7C enclosure can be mounted by screwing the base conduit hub onto an appropriate size free-
standing conduit or by using the mounting holes in each corner of the enclosure.
DO NOT DRILL HOLES THROUGH THE ENCLOSURE FOR MOUNTING!

This can allow water into the enclosure causing a potential shock hazard. It is recommended that a
weatherproof junction box be mounted below the DS-7C for termination of the power and load pigtails to
the equipment/building wiring.
Use Care When Replacing the Front Cover. Do Not Pinch the Gasket or Overtighten the Screws.

Moisture Grid Maintenance & Replacement
It is recommended that the DS-7C be powered down and the moisture grid wiped clean with clear water at
least once every 4 months. Heavy deposits may be removed using a non-metallic scouring pad (Scotch-
Brite
TM
or equivalent.) However, after a number of years, the corrosive elements left behind when water is
evaporated out of the moisture grid will eventually damage the grid rings. The moisture grid can be easily
replaced by ordering and installing a new MG-6 “Moisture Grid Assembly”. Reference the
“Moisture
Sensor Mounting & Termination”
section for information on replacing the moisture grid.
