Types C100 and F100Remove cover. Switch has a hex screw adjust-ment inside enclosure. If switch transfer pointdiffers from actual temperature, adjust setting.To raise the temperature setting, turn the hex in(clockwise), and to lower the setting turn thescrew out (counterclockwise). When makingadjustments, do not exceed the maximumtemperature rating on nameplate.Types B100 and E100 (with reference dial)Controls are factory calibrated for maximumaccuracy at the midpoint of the scale.To re-calibrate, turn dial to desired set point. Ifthe actual temperature and set point tempera-ture do not agree, turn adjustment screw clock-wise to raise and counterclockwise to lowertemperature setting.Tools NeededFlathead screwdriverU S E O N L Y F A C T O R Y A U T H O R I Z E DREPLACEMENT PARTS AND PROCE -DURES.

Before installing a unit, the Installation andMaintenance instructions provided with unit must be read andunderstood.• To avoid damaging unit, proof pressure and max temperature lim -its stated in literature and on nameplates must never be exceeded,even by surges in the system. Operation of the unit up to proof pressureor max temperature is acceptable on a limited basis (i.e.start-up, test-ing) but continuous operation must be restricted to the designatedadjustable range. Excessive cycling at proof pressure or maximum tem -perature limits could reduce sensor life.• A back-up unit is necessary for applications where damageto a primary unit could endanger life, limb or property. A high or low limitswitch is necessary for applications where dangerous runaway condi-tion could result.• The adjustable range must be selected so that incorrect,inadvertent or malicious setting at any range point can not result in anunsafe system condition.• Install unit where shock, vibration and ambient temperaturefluctuations will not damage unit or affect operation. Orient unit sothat moisture does not enter the enclosure via the electricalconnection.• Unit must not be altered or modified after shipment. Consult UE ifmodification is necessary.• Monitor operation to observe warning signs of possible damageto unit, such as drift in set point. Check unit immediately.• Preventative maintenance and periodic testing is necessary forcritical applications where damage could endanger property orpersonnel.• For all applications, a factory set unit should be tested before use.• Electrical ratings stated in literature and on nameplate must not beexceeded. Overload on a switch can cause damage, even on the firstcycle. Wire unit according to local and national electrical codes, usingwire size recommended in installation sheet.• Use only factory authorized replacement parts and procedures.• Do not mount unit in ambient temp. exceeding published limits.• For remote mounted temperature units, capillary lengths beyond10 feet can increase chance of error, and may requirere-calibration of set point and indication.LIMITED WARRANTYUE warrants that the product thereby purchased is, upon delivery, freefrom defects in material and workmanship and that any such productwhich is found to be defective in such workmanship or material will berepaired or replaced by UE (F.O.B.
