RECOMMENDED PRACTICES AND WARNINGS

United Electric Controls Company recommends careful considerationof the following factors when specifying and installing UE pressure andtemperature units. Before installing a unit, the Installation and Maintenanceinstructions provided with unit must be read and understood.

To avoid damaging unit, proof pressure and maximum temperature limitsstated in literature and on nameplates must never be exceeded, even bysurges in the system. Operation of the unit up to maximum pressure ortemperature is acceptable on a limited basis (e.g., start-up, testing) butcontinuous operation must be restricted to the designated adjustable range.Excessive cycling at maximum pressure or temperature limits could reducesensor life.

A back-up unit is necessary for applications where damage to a primaryunit could endanger life, limb or property. A high or low limit switch isnecessary for applications where a dangerous runaway condition couldresult.

The adjustable range must be selected so that incorrect, inadvertent ormalicious setting at any range point cannot result in an unsafe systemcondition.

Install unit where shock, vibration and ambient temperature fluctuationswill not damage unit or affect operation. Orient unit so that moisture doesnot enter the enclosure via the electrical connection. When appropriate,this entry point should be sealed to prevent moisture entry.

Unit must not be altered or modified after shipment. Consult UE ifmodification is necessary.

Monitor operation to observe warning signs of possible damage to unit,such as drift in set point or faulty display. Check unit immediately.

Preventative maintenance and periodic testing is necessary for criticalapplications where damage could endanger property or personnel.

For all applications, a factory set unit should be tested before use. Electrical ratings stated in literature and on nameplate must not be

exceeded. Overload on a switch can cause damage, even on the first cycle.Wire unit according to local and national electrical codes, using wire sizerecommended in installation sheet.

Do not mount unit in ambient temp. exceeding published limits.
