RECOMMENDED PRACTICES AND WARNINGS
United Electric Controls Company recommends careful consideration of the fol-
lowing 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.
• Toavoiddamagingunit,proofpressureandmaximumtemperaturelimitsstated
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 accept-
able 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.
• Aback-upunitisnecessaryforapplicationswheredamagetoaprimaryunit

for applications where a dangerous runaway condition could result.

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.
