10.3 Air Purging - (Continued)
 5.  With the vacuum pump still running, close 
      the "Low" knob of the manifold valve. Then
      stop the vacuum pump.
 6.  With the accessory hex wrench, turn the 
      valve stem on the narrow tube service valve 
      counter-clockwise by 90 degrees (1/4 turn)  
      for 10 seconds, and then turn  the stem  
      clockwise to close it again.  (Fig.36) 
     
      Be sure completely insert the hex 
      wrench before attempting to turn  
      the valve.
 7.  Leak test all joints at tubing (both indoor and 
      outdoor) with liquid soap. Bubbles indicate a 
      leak. Be sure to wipe off the soap with a 
      clean cloth.
 8.  WIth the hex wrench, turn the wide tube 
      service valve stem counter-clockwise to fully 
      open the valve.
 9.  Turn the narrow tube service valve stem 
      counter- clockwise to fully open the valve.
10. Loosen the vacuum hose connected to the  
      wide tube service port slightly to release the 
      pressure. Then, remove the hose.
 
      This may cause the refrigerant gas 
      to leak. In order to avoid this, take 
      off the hose quickly.
11. Fasten the valve cap on the wide tube 
      service port securely with an adjustable 
      wrench or box wrench. Next, mount the 
      valve cap on the service valve and
      tightened it to 200 kg-cm with a torque 
      wrench. This process is very important to 
      prevent gas leaking from the system.
12. Test run the air conditioner. (See page 33)
13. While the air conditioner is running, apply       
      liquid soap to check for any gas leaks       
      around the service valves or caps. 
14. If there is no leakage, stop the air 
      conditioner.
     
15. Wipe off the soap on the tubing.
This completes air purging with a 
vacuum pump and the air conditioner is 
ready for actual operation.
