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 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 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 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. Mount the 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.
