TYPICAL INSTALLATION SWICHGAGE INSTALLATION (Refer to drawing) 1.  Secure the  SWICHGAGE  in  the  panel,  using  the  clamp and nuts provided. NOTE  G:  Be  sure  the  SWICHGAGE  and panel are grounded. 2.  If necessary, drain coolant or lubricant to a level below the sensor entry point.  Prepare the MURPHY adaptor nut (others may  damage  bulb)  with  teflon  tape  or  pipe  dope  and  screw securely into place. 3.  Slide the sending bulb through the adaptor and secure with the  union  nut.    If  necessary,  refill  the  system  to  operational level. NOTE   B:   Use   only   the   union   nut   to remove   the   bulb.      When   refilling   the system,  loosen  the  union  nut  until  fluid flow    then    tighten;    this    prevents    air pockets in the adaptor. 4.  Wire the limit  switch(es)  to  a  Murphy  magnetic  switch  or relay. NOTE F: Light duty (2 A @ 30 V resistive) front   contacts   must   be   protected   from high   current:   disconnect   power   during wire-up. CAUTIONS: (Refer to drawing) A.      Avoid   sharp   bends,   especially   at gauge and at adapter: minimum diameter 2”/50 mm. C.  Bulb must be immersed in coolant or lubricant to operate N. properly.  Be sure obstructions  do  not  damage  bulb  when in-serted.  Insert bulb to full depth. D.      If   going   through   a   firewall,   use  a grommet or other protective surrounding. E.  Coil and secure excess capillary tube. Keep     tube     away     from     other     high temperature components. TEST: Start equipment and check readings; close limit switch or cause engine to heat to alarm/shut-down point. USE THE PROPER TOOLS - DO NOT OVERTIGHTEN Murphy recommends mounting SWICHGAGES and magnetic switches away from excessive vibrations and the use of panel shock   mounts   wherever   vibration   may   occur.      Handle   all instruments with care: although durable, these products should not   be   subjected   to   rough   handling,   dropping,   or   severe vibrations. Magnetic   Switches:   Mount   with   electrical   lugs   down.      If necessary,    drill    the    TATTLETALE^â     and    pilot-stud    holes (template provided); clean away burrs and filings.  Position the magnetic switch in the panel, making sure the pilot stud is in place.  Add TATTLETALE^â  decal, then washer, then nut and tighten. BASIC    WIRING    OF    SWICHGAGEâ     AND    MAGNETIC SWITCH Disconnect battery or other power during installation Murphy components are easily wired-up and maintained Use good quality wire and terminals.  Be sure all connections are Clean, Complete, and Correct.  The wiring and the type of magnetic switch differ for various applications, but a knowledge of  basic  electrical  functions  and  of  the  circuits  necessary  for the specific job (what you want to happen), and commonsense will make the system work-the way you want it to work. See  examples  of  typical  wiring  and  instructions  packed  with each magnetic switch. IMPORTANT, PLEASE READ COMPLETELY SWICHGAGE    Murphy     magnetic     switches     and     valves, properly  installed  and  maintained,  are  effective,  work-ready tools  in  any  preventive  maintenance  program.    For  optimum performance,  check  these  tools  periodically:  look  for  frozen pointers,   Kinked   or   worn   tubing,   broken   wiring   or   loose connections:   close   the   contacts,   then   watch   for   expected results.  Replace any damaged or worn parts: clean and repair as  necessary  Murphy  will  repair  or  replace  parts  covered  by the Murphy two year limited warranty Check  the  wiring:  it  must  be  Correct  and  Complete: tight     connections,     unbroken     insulation,     no     accidental grounds, do not run shut-down wires with ignition wiring. Check all tubing and connections for leaks. Mount  magnetic  switches  and  Murphy  valves  in  an upright position, to prevent moisture collection and shorting. CLEANING:  If  steam  cleaning  will  be  used,   epoxy   seal   all magnetic   switches.      Cleaning   Lexan   Lenses:   since   many strong   solvents   and   cleaners   can   haze   and   permanently damage   the   clear   polycarbonate   lens   on   SWICHGAGES^â , please  use  one  of  the  solutions  listed  here:   mild  soap  and water;   mineral    spirits;    white    kerosene;    VM&P    naphtha, heptane,    hexane,    varsol    No.    2;    methyl/isopropyl/isobutyl alcohols; 1 & 3 denatured alcohols: freons TF & TE; petroleum ether (65C boiling pt.) CAUTION:   Many   of   these   cleaners   are flammable.      DO   NOT   USE   when   the equipment  is  running  or  very  not  .Keep away from sparks and flame. #064334CMA
