RECOMMENDED PRACTICES AND WARNINGS
United Electric Controls Company recommends careful consideration of the following factors when
specifying and installing UE pressure and temperature units. Before installing a unit, the Installation
and Maintenance instructions provided with unit must be read and understood.
• To avoid damaging unit, proof pressure and max. temperature limits stated in literature
and on nameplates must never be exceeded, even by surges in the system. Operation of the unit up
to proof pressure or max. temperature is acceptable on a limited basis (i.e., start-up, testing) but
continuous operation must be restricted to the designated adjustable range. Excessive cycling at proof
pressure or maximum temperature limits could reduce sensor life.
• A back-up unit is necessary for applications where damage to a primary unit could
endanger life, limb or property. A high or low limit switch is necessary for applications where dangerous
runaway conditions could result.
• The adjustable range must be selected so that incorrect, inadvertent or malicious setting
at any range point cannot result in an unsafe system condition.
• Install unit where shock, vibration and ambient temperature fluctuations will not damage unit or
affect operation. Orient unit so that moisture does not enter the enclosure via the electrical
connection.
• Unit must not be altered or modified after shipment. Consult UE if modification is necessary.
• Monitor operation to observe warning signs of possible damage to unit, such as drift in set
point. Check unit immediately.
• Preventative maintenance and periodic testing is necessary for critical applications 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 size recommended in installation sheet.
• Use only factory authorized replacement parts and procedures.
• Do not mount unit in ambient temp. exceeding published limits.
