1. Make sure that you have the required tools available (pipe cutter, reamer,flaring tool and pipe holder).
2. If you wish to shorten the piping, cut it using a pipe cutter, taking care to ensure that the cut edge remains at a
90° angle with the side of the pipe,and referring to the illustrations below for examples of edges cut correctlyand
incorrectly.
3. To prevent any gas from leaking out, remove all burrs at the cut end of the pipe, using a reamer.
4. Slide a flare nut on to the pipe and modify the flare.
5. Check that the flaring is correct, referring to the illustrations below for examples of incorrect flaring.
6. Align the pipes to be connected and tighten the flare nuts first manually and then with a torque wrench, applying the
following torque.
7. For further details on how to connect up to the outdoor unit and purge the circuit, refer to page 10.
While heating, ice may accumulate. During the process of
defrosting, check if condensation draining is adequate.
For adequate draining, do the following :
1. Insert the drain plug into the drain hole on the underside of
the outdoor unit.
2. Connect the drain hose to the drain plug.
3. Ensure that condensation draining is adequate.
