5-25.  Receiver a.  Removal.   Refer   to   paragraph   6-3   and discharge   the   refrigerant   system.   Refer   to paragraph 4-21 and remove rear top cover. Remove four  screws  and  two  mounting  straps  (fig.  5-8). Disconnect  receiver  tubing. b.   Installation.   Install  receiver  and  solder connections.  Install  two  mounting  straps  and  four screws  using  sealing  compound  on  screw  threads. Refer  to  paragraph  6-3  and  charge  the  refrigerant system. 5-26.  Liquid  Sight  Indicator a.  Removal.  Refer   to   paragraph   6-3   and discharge  the  refrigerant  system.  Remove  housing rear top cover (para 4-21). Remove two screws and lock  washers  from  sides  of  liquid  sight  indicator (fig. 1-2) and remove mounting bracket from inside housing.   Unsolder   liquid   sight   indicator   from tubing. b.  Installation.  Solder  liquid  sight  indicator  on tubing.  Place  bracket  over  indicator  on  inside  of housing  and  secure  with  two  screws  and  lock washers. Install housing top rear cover (para 4-21). Refer  to  paragraph  6-3  and  charge  the  refrigerant system. 5-27.  Solenoid  Valves a. Removal.  Removal  procedures  for  the  bypass solenoid valve and the equalizer solenoid valve are the same. (1)  Refer  to  paragraph  6-3  and  discharge  the refrigerant system. (2)  Refer  to  paragraph  4-21  and  remove housing  rear  top  cover. (3)  Disconnect  solenoid  valve  electrical connector. (4)  Remove  two  socket-head  cap  screws  from underside  of  valve  body  and  carefully  remove bonnet   assembly.   Do   not   drop   plunger.   Remove diaphragm. Caution: Remove bonnet assembly and diaphragm before applying heat to valve body. (5)  To  remove  liquid  bypass  solenoid  valve (fig.  5-8),  remove  two  screws  and  spacers  and unsolder   valve   body   from   tubing.   Remove bushings. (6)  Follow  same  procedure  and  remove equalizer  solenoid  valve  body. b.  Installation.   Install  each  solenoid  valve  as follows  : (1)  Install  bushings  in  valve  body  and  solder body  on  tubing. (2)  Install  spacers  between  body  and  housing and  install  two  screws  from  outside  of  housing. (3) Place diaphragm in the body with the pilot port extension away from body. Hold plunger with synthetic    seat    against    pilot    port.    Make    sure preformed  packings  are  in  place  and  lower  bonnet assembly  over  plunger.  Install  body  screws. (4)  Connect  electrical  connector. (5)   Refer   to   paragraph   4-21   and   install housing  rear  top  cover. (6)  Refer  to  paragraph  6-3  and  charge  the refrigerant  system. 5-28.  Thermal  Expansion  Valve a. General. The main thermal expansion valve is hermetically  sealed  and  cannot  be  repaired. b.  Removal.   Remove   the   thermal   expansion valve  as  follows: (1)  Refer  to  paragraph  6-3  and  discharge  the refrigerant  system. (2)  Remove  housing  top  covers  (para  4-21). (3)  Soften  mastic  in  bulb  well  (fig.  5-9)  and remove   bulb   from   well.   Take   care   to   prevent damage  to  capillary  tube. (4)  Unsolder  thermal  expansion  valve  from tubing. 5-13
