CARE MUST BE TAKEN TO AVOIDIGNITION HAZARD DUE TO IMPACT OR FRICTION.PROOF PRESSURE * LIMITS LISTED ON NAMEPLATE MUSTNEVER BE EXCEEDED, EVEN BY SURGES IN THE SYSTEM.OCCASIONAL OPERATION OF UNIT UP TO PROOFPRESSURE IS ACCEPTABLE, E.G., START-UP AND TESTING.CONTINUOUS OPERATION SHOULD NOT EXCEED THEDESIGNATED OVER RANGE ** OR MAXIMUM WORKINGPRESSURE *** RANGE.* Proof Pressure - the maximum pressure to which a pressure sensormay be occasionally subjected, which causes no permanent damage(e.g., start-up, testing). The unit may require re-gapping.** Over Range Pressure - the maximum pressure to which a pressuresensor may be continuously subjected without causing damage andmaintaining set point repeatability.*** Working Pressure Range - the pressure range in which two oppos-ing sensors can be safely operated and still maintain set point providedthe difference in pressure between the low and high sides does notexceed the designated adjustable range.THIS PRODUCT DOES NOT HAVE ANY FIELDREPLACEABLE PARTS. ANY SUBSTITUTION OFCOMPONENTS SHALL INVALIDATE AGENCYCERTIFICATION(S).DEVICE MUST NOT BE ALTERED OR MODIFIED AFTERSHIPMENT. CONSULT UE IF MODIFICATION IS NECESSARY.The 100 Series pressure and differential pressureswitches are activated when a bellows, diaphragm orpiston sensor responds to a pressure change. Thisresponse, at a pre-determined set point, actuates asingle snap-acting switch, converting the pressuresignal into an electrical signal. Control set point maybe varied by turning the internal adjustment hex. (SeeAdjustment - PART II). Please refer to the datasheetat www.ueonline.com for product specifications.Date code format on nameplate is “YYWW” for yearand week.Part I - Installation• Adjustable wrench• Screwdriver• Hammer (for alternate wire knockouts)MountingINSTALL DEVICE WHERE SHOCK, VIBRATION ANDTEMPERATURE FLUCTUATIONS ARE MINIMAL. DO NOTINSTALL DEVICE IN AMBIENT TEMPERATURES THATEXCEED PUBLISHED LIMITS ON THE NAMEPLATE.DEVICE SHOULD BE MOUNTED TO PREVENTMOISTURE FROM ENTERING THE ENCLOSURE.VERTICAL MOUNTING IS RECOMMENDED.CONSIDER THE USE OF A PRESSURE SNUBBER IFSEVERE PRESSURE SURGES ARE EXPECTED.FOR PRESSURE MODELS, MOUNT VIA PRESSURECONNECTION. ALWAYS USE A WRENCH ON PRESSURECONNECTION HEX. DO NOT TIGHTEN BY TURNINGTHE ENCLOSURE AS THIS WILL DAMAGE THE SENSORAND WEAKEN WELDED JOINTS.100 SeriesType H100 (Pressure Switch)Type H100K (Differential Pressure Switch)Installation and Operation InstructionsPlease read all instructional literature carefully and thoroughly before starting.Refer to the final page for the Warranty.
