BarFlare nut Fix pipe turning clamp handle. Pipe • See the “Determination of Installing Position”. Connecting of Tubing 1. Cutting and flaring of tubing: A. Cut the tubing on its straight part with the pipe cutter. B. Remove burrs from cut edges of pipes, which may cause a gas leak. C. Flaring of the pipe is done with the flaring tool. NOTE: Do not forget to install the flare nut before flaring 2. Pre-Connecting: Screw the tubing turning 3 to 5 times until hand tight. 3. Fastening: Fasten the connection. • Apply refrigeration oil to the flare surface to pre- vent gas leakage. Air Purge and Charging! CAUTION ! 1) Remove the cap from the service port on the suction line service valve. 2) Connect the suction side of the refrigerant gauge manifold to the Suction Line service valve. Connect the center hose of the refrigerant manifold gauge to the micron gauge. Connect the other side of the micron gauge to the vacuum pump. (Diagram 1) 3) Open the suction side of the refrigerant manifold set and turn the vacuum pump on. NOTE: Evacuate the system down to 400 microns. 4) When the system pulls down to 400 microns turn the vacuum pump off. Observe the micron gauge: if the system has a leak the gauge will detect it. If there is a leak, find it, repair it, and repeat steps 3 and 4. 5) Close the refrigerant gauge manifold valve and disconnect the vacuum pump from the system. 6) Remove the Suction and Liquid line Service Valve Caps from the valves. 7) Using an Allen wrench, open the Liquid Line Service Valve until the valve is in the fully open position. Next do the same for the Suction Line Service valve. NOTE: Be careful as not to completely remove the valve core from the valve. This will result in the release of refrigerant from the system into the atmosphere! 8) Re-install the caps on both service valves. This completes the charging of the system.
