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 lit-
erature 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 lim -
ited basis (i.e.start-up, testing) but continuous operation must be restricted to the des-
ignated adjustable range. Excessive cycling at proof pressure or maximum tempera -
ture 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 appli-
cations where dangerous runaway condition could result.
• The adjustable range must be selected so that incorrect, inadvertent or mali-
cious setting at any range point can not 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 enclo -
sure 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 applica -
tions 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.
• For remote mounted temperature units, capillary lengths beyond 10 feet can
increase chance of error, and may require re-calibration of set point and indication.
