It is recommended that the sensor(s) be kept at room temperature
for at least 24 hours before installation to allow any condensation
that may have accumulated due to low temperature during
shipping/storage to evaporate.
Upon unpacking the product, inspect the contents of the carton
for shipping damages. Do not install damaged controllers.
Allow for proper clearance of sensor enclosure, wiring terminals
and hardware configuration and maintenance.
Each controller is designed to operate under the following
environmental conditions:
• Ambient temperature from 32°F to 122°F (0°C to 50°C)
• Relative humidity from 0% to 95%, non-condensing
Ensure proper ventilation of each sensor and avoid areas where
corroding, deteriorating or explosive vapors, fumes or gases may
be present.
Do not drop the sensor or subject it to physical shock.
Any type of modification to any Phoenix Controls
product will void the product's warranty.
Take special care to keep the front and back plate aligned
when separating and joining them.
