ARMY TM 9-4120-381-14 NAVY EE-000-CA-MMA-010/7053-AC AIR FORCE TO 35E9-136-31 5-10. EVAPORATOR MOTOR (B1). This task covers:  Service INITIAL SETUP Tools: Tool kit, service, refrigeration unit (Item 1, Appendix B) Gloves, chemical (Appendix C) Goggles, industrial (Appendix C) Personnel: 1 WARNING DANGEROUS CHEMICAL (R-22) is used in this equipment. DEATH or severe damage may result if personnel fail to observe safety precautions.  Use great care to avoid contact  with  liquid  refrigerant  or  refrigerant  gas  being  discharged  under  pressure.    Sudden  and irreversible  tissue  damage  can  result  from  freezing.    Wear  thermal  protective  gloves  and  a  face protector   or   goggles   in   any   situation   where   skin-eye-contact   is   possible.      Prevent   contact   of refrigerant  gas  with  flame  or  hot  surfaces.    Heat  causes  the  refrigerant  to  break  down  and  form carbonyl chloride (phosgene), a highly poisonous and corrosive gas. REFRIGERANT UNDER PRESSURE is used in the operation of this equipment. DEATH or severe Injury may result if you fall to observe safety precautions.  Never use a heating torch on any  part  that  contains  R-22  refrigerant.    Do  not  let  liquid  refrigerant  touch  you,  and  do  not  Inhale refrigerant gas. REPAIR 1. The  refrigeration  system  must  be  totally  discharged  before  performing  any  maintenance  action  that  requires opening of the pressurized system (para 5-12). 2. The drier filter replacement and leak testing are required after any system component has been removed and re- placed (para 5-26 and para 5-15). 3. The system must be evacuated before it is charged (para 5-16). 4. The system must be properly charged to function properly (para 5-17). 5-17
