RECOMMENDED PRACTICES AND WARNINGS 

United Electric Controls Company recommends careful consideration 
of the following factors when specifying and installing UE pressure and temper-
ature units. Before installing a unit, the Installation and Maintenance instruc-
tions 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 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.

•  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.

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
