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 nec-
essary 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. When applicable, 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 modifi-
cation 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 ap-
plications where damage could endanger property or personnel.
• Electrical ratings stated in literature and on nameplate must not be ex-
ceeded. 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.
