QUICK INSTALL
1. Choose an outdoor location in a sheltered area, out of direct sunlight.
2. Mount unit with probe pointing down. Unit may be suspended by conduit. Do not
obstruct vent openings.
3. Wire probe (see Wiring section). Leave wires at factory length to allow for a service
loop (to remove sensor from junction box for service without disturbing the
conduit).
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.
