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. 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.
