United Electric Controls Company recommends careful considerationof the following factors when specifying and installing UE pressureand temperature units. Before installing a unit, the Installationand Maintenance instructions provided with unit must be read andunderstood.
• Toavoiddamagingunit, proof pressure andmaximum temperaturelimitsstatedinliteratureandonnameplatesmustneverbeexceeded,evenby surges in the system.Operationof theunitup tomaximumpressure or temperature is acceptable on a limited basis (e.g.,start-up, testing) but continuous operationmustbe restricted to thedesignatedadjustablerange.Excessivecyclingatmaximumpressureortemperaturelimitscouldreducesensorlife.
• A back-up unit is necessary for applications where damage toa primary unit could endanger life, limb or property. A high orlow limit switch is necessary for applications where a dangerousrunawayconditioncouldresult.

• Install unit where shock, vibration and ambient temperaturefluctuations will not damage unit or affect operation. Whenapplicable,orientunitsothatmoisturedoesnotentertheenclosurevia the electrical connection. When appropriate, this entry pointshouldbesealedtopreventmoistureentry.
• Monitor operation to observe warning signs of possible damageto unit, such as drift in set point or faulty display. Check unitimmediately.
• Preventative maintenance and periodic testing is necessary forcritical applications where damage could endanger property orpersonnel.
