38 Capricorn 2000EX Weather Station

Columbia Weather Systems, Inc.
Installing the Mast
The Capricorn 2000EX will measure wind speeds of up to 160 mph (257
km/h). However, unless the Wind Sensor Assembly is properly mounted
to withstand such high winds, this capability is useless. Please read
these instructions carefully to insure a safe and reliable installation.
There are three acceptable methods for mounting the mast to a roof or
building structure: Sloped roof mounting, flat roof mounting or wall
mounting. See Section 4: Optional Sensor Mounting Hardware for more
information.
Location
Do not attach the Wind Sensor Assembly to a chimney or any other
transmitting mast or tower.
Select a mounting location that will allow the Wind Sensor Assembly
cables to be routed away from any other data cables to avoid
interference.
Do not mount sensors close to power lines or in tall trees.
Mounting Method
Choose the appropriate mounting method for the installation and obtain
the necessary mounting hardware. Refer to Section 4 for information on
optional sensor mounting hardware and accessories which are available
from the factory.
If the mounting hardware is not obtained from the factory, be certain to
use metal parts which are plated or galvanized to assure maximum
longevity.
In marine locations (or other areas) which experience severe corrosion
problems, a watertight, rubberized spray coating is recommended. This
can be sprayed on all metal parts from the cross arm support down (not
the wind sensors) after the installation is completed.
Secure the mast to the roof, using guy wires with sufficient tensile
strength. The Wall Mounting Method should utilize a mast of no more
than 5 ft. maximum height, unless it can be secured with guy wires.
Routing Cable
Use plastic tie wraps secure the cable to mast. Be sure that one is used
at the mast base. Tighten the tie wraps securely and clip off any excess
length with a wire cutter tool.
Route the cable back to the Control Module. If mounting on a roof, route
the sensors through a vent or other opening into an attic or crawl space.
