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 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 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 electri-
cal 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 neces-
sary.
•
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.
