6. Place flaring tool onto the form. Instructions for Connecting Piping to 7. Turn the handle of the flaring tool clockwise Indoor Unit until the pipe is fully flared. 8. Remove the flaring tool and flare form, then 1. Align the center of the two pipes that you will inspect the end of the pipe for cracks and connect. See Fig. 5.7 . even flaring. AIM r. Step 4: Connect pipes 0 When connecting refrigerant pipes, be careful I not to use excessive torque or to deform the piping in any way. You should first connect the Indoor unit tubing Flare nut Pipe low-pressure pipe, then the high-pressure pipe. Fig. 5.7 MINIMUM BEND RADIUS 2. Tighten the flare nut as tightly as possible by When bending connective refrigerant piping, hand. the minimum bending radius is 10cm. See 3. Using a spanner, grip the nut on the unit Fig..5.6 tubing. 4. While firmly gripping the nut on the unit IOV"*, tubing, use a torque wrench to tighten the ,+''»,4 flare nut according to the torque values in the AP/. *4% Torque Requirements table below.
