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 maximum temperature limits
stated in literature and on nameplates must never be exceeded, even by
surges in the system. Operation of the unit up to maximum pressure or
temperature is acceptable on a limited basis (e.g., start-up, testing) but
continuous operation must be restricted to the designated adjustable range.
Excessive cycling at maximum pressure or 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 a dangerous runaway condition 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. When appropriate,
this entry point should be sealed to prevent moisture entry.
• 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 or faulty display. 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.
• Do not mount unit in ambient temp. exceeding published limits.
