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 sys-
tem. 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 mali-
cious 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 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 applica-
tions where damage could endanger property or personnel.
• 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.
