WIRING OPENING
The use of a standard 2 X 4 inch electrical box to accommodate the wiring is recommended for installation. The sensor can be mounted directly on the wall, if acceptable by local codes.
!CAUTION
UNIT DAMAGE HAZARD
Failure to follow this caution may result in permanent damage to the sensor.
DO NOT clean or touch the sensing element with chemical solvents as they can permanently damage the sensor.
!CAUTION
UNIT PERFORMANCE HAZARD
Failure to follow this caution will result in inaccurate sensor readings.
DO NOT mount the sensor in drafty areas such as near heating or
If the sensor is installed directly on a wall service, install the humidity sensor using 2 screws and 2 hollow wall anchors (field supplied). Do not over tighten screws. See Fig. 58.
The sensor must be mounted vertically on the wall. The Carrier logo should be orientated correctly when the sensor is properly mounted.
Avoid corner locations. Allow at least 4 ft between the sensor and any corner. Airflow near corners tends to be reduced, resulting in erratic sensor readings. The sensor should be vertically mounted approximately 5 ft up from the floor, beside the space temperature sensor.
For wiring distances up to 500 feet, use a

To wire the sensor:
1.At the sensor, remove 4 inches of the jacket from the cable. Strip 1/4 inch of insulation from each conduct- or. Route the cable through the wire clearance open- ing in the center of the sensor. See Fig. 58.
