Figure 7-1 Sensor Probe Replacement
If your HX92B will be used in a dusty environment, the protective sensor filter
(if clogged) may be removed for cleaning.
Unscrew the protective cover and gently blow compressed air through the filter
screen. A soft brush may also be used to remove dirt particles from the screen.
If the sensor is subjected to 100% condensation, it must be dried to obtain correct
readings. There will be no permanent damage or calibration shift to the unit.
Units should not be exposed to high concentrations of ammonia or alcohol
vapors.
The Duct Mount model transmitter must be sent back to the factory if sensor
replacement or recalibration is needed.
