ARMY TM 9-4210-381-14 NAVY EE-000-CA-MMA-010/7053-AC AIR FORCE TO 35E9-136-31 WARNING High voltage is used in operation of this equipment.  DEATH ON CONTACT may result if personnel fail to observe safety precautions. 7. Connect air conditioner input power at source. 8. Start air conditioner in COOL mode. 9. Allow air conditioner to run about 30 minutes. 10. Check to be sure temperature in suction line has stabilized and thermocouple meter reading remains unchanged for at least two minutes. 11. Note  pressure  on  manifold  gauge  connected  to  low  pressure  expansion  (primary)  service  valve.    Identify saturation  temperature  for  pressure  gauge  reading  (see  Table  5-2)  and  compare  with  thermocouple  meter reading.    The  thermocouple  meter  temperature  should  be  8  to  15°F  (4.48  to  8.4°C)  higher  than  saturation temperature found in Table 5-2. 12. If the superheat setting is not within limits shown in step 11, adjust expansion valve as follows: a. Remove service valve cap (2) from side of power assembly (1). NOTE Do  not  change  more  than  two  full  turns  at  one  time,  then  wait  five  to  ten  minutes  for  temperature  to stabilize and recheck pressure and temperature before further adjustment. b. Turn adjusting stem two complete turns to change superheat setting by 1 °F.  Turn clockwise to increase superheat span or counterclockwise to decrease superheat span. c. If  expansion  valve  can  not  be  adjusted  to  within  limits  shown  in  step  11,  contact  General  Support Maintenance. WARNING Disconnect input power to the air conditioner before performing any internal maintenance.  Voltages used can KILL.  Shutting the unit off at the control panel does not disconnect unit power. 13. Disconnect air conditioner input power at source. 14. After proper setting is obtained: a. Turn unit OFF. b. Install service valve cap (2) c. Remove thermocouple. d. Remove service manifold from service expansion (primary) valve. e. Remove wires installed to TB-2 in step 3. f. Close left electric plate (para 4-30). g. Close manual valve (para 5-39). FOLLOW ON PROCEDURE 1. Perform start up after repairs (para 5-22). 2. Close control box (para 4-45). 3. Install right front condenser panel (para 4-28). 5-85
