IS3100-1 1/84 REGULATOR INSTRUCTION SHEET AIR LINE REGULATORS-SERIES 1500 Standard Units-Relieving "NR" Designates-Non Relieving Maximum Supply Pressure-300 PSI Operating Temperature Range-40F to 120F INSTALLATION  -  Install  regulators  so  the  airflow  is  in the  direction  “IN-OUT”  as  indicated  on  the  head  of  all units.    Regulators  should  be  installed  downstream  from filters   or   upstream   from   lubricators,   but   as   close   as possible   to   the   pneumatic   tools   or   appliances   being serviced.  The regulator will accurately control secondary pressure  between  2  and  125  P.S.I.,  maximum  primary pressure  300  P.S.I.    The  selfbleed  feature  permits  use on dead-end applications. WARNING - Units are die cast aluminum, do not over torque  when  installing  regulator  or  gauge.    Use  of Teflon tape is not recommended. OPERATION   ADJUSTMENTS  -   After   the   regulator   is installed,  back  off  pressure  adjusting  screw  before  the air  is  turned  on.    This  will  relieve  compression  on  the regulating  spring.    Turn  on  the  air  supply  and  regulate the  adjusting  screw  until  the  pressure  gauge  shows  the desired pressure. MAINTENANCE  -  On  detection  of  air  leaks,  pressure fluctuation,  or  'creep";  depressurize  system  and  remove back   cap.      Inspect   valve   seat   for   damage   or   wear. Inspect   seat   In   head   casting   for   foreign   material   or damage.    Clean  with  kerosene  and  blow  out  with  air. Replace any damaged parts. If  leaks  persist;  remove  bonnet,  Inspect  diaphragm  and diaphragm  seat  for  wear  or  foreign  material.    Replace damaged or worn pats. WARNING!  For compressed air service only.  Not to be used on life support systems.
