ISSUE 1 Installation Instructions for the HIH-4010/20/21 Humidity Sensors WARNING PERSONAL INJURY • DO NOT USE these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury. • The sensor’s housing does not provide electrical safety isolation. Mount the sensor in a location where it cannot be touched, or where a surrounding barrier prevents human contact. Failure to comply with these instructions could result in death or serious injury. CAUTION IMPROPER HANDLING • Do not remove the sensor from its original protective packaging until it is ready to be installed. • Do not touch the sensor surface. Use latex finger cots. Handle the sensor by its package edges or leads. • Do not allow objects to enter the cavity of the sensor element. Failure to comply with these instructions may result in product damage. NOTICE • Under condensing conditions where enough liquid water forms on the sensor to create a parasitic leakage path, the HIH-4010/20/21 Series Humidity Sensor produces an erroneous reading of 0% humidity. If this erroneous reading is assumed to be correct by your control function, excess humidity is likely to be introduced into the system. Once the liquid water evaporates from the sensor and the environment returns to a non-condensing state, the device returns to normal functionality. • Shade the sensor from direct light. Intense direct light can flood junctions in the CMOS (Complementary Metal Oxide Semiconductor) device and drive the output signal to the minimum. This does not harm the sensor or affect calibration. Proper operation resumes shortly after the direct light is removed. Ambient scattered light normally does not affect performance. • At the end of its working life, dispose the sensor in accordance with Directive 2002/96/EC (WEEE).

Failure to comply with these instructions may result in product damage. CAUTION IMPROPER SENSOR POSITIONING • Position the sensor so that its face is exposed to the atmosphere being monitored. Failure to comply with these instructions may result in product damage Hand soldering is acceptable. If wave soldering is required, use a no-clean flux. Limit the contact of the flux to the leads only. Recommended PC board wave soldering temperature is o o o o 250 C to 260 C [482 F to 500 F]. MOISTURE SEALING THE LEADS If, in the presence of intermittent moisture or other contaminants, there is the possibility of galvanic paths between the leads, moisture seal the leads and exposed pads.
