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.  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.

•  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.

•  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.

LIMITED WARRANTY

Seller  warrants  that  the  product  hereby  purchased  is,  upon  delivery,  free  from 
defects in material and workmanship and that any such product which is found to
