In relation to the bracket shown above, the unit
is shipped with the drain hose connection on the
right, the drain hose exits the unit on the left, and
the refrigerant pipes are bent to exit on the left.
Thus, positioning the hole to the left requires the
least effort. If you position the hole to the right
or below the unit, you will need to move the drain
hose connection to the left and bend the pipes so
that the hose and pipes exit to the right or bottom.
See the figure in Step 7.

Use a standard 2.56 inch(65mm) hole saw to drill one hole
at the selected location, at a 15° downward angle so that
the drain hose will drain properly.

Based on the hole location, determine where the piping
bundle (drain hose, refrigerant pipes, and cables) will exit
the unit.

The left, right, or bottom exit will only be used if the
hole is not positioned behind the unit.
Step 5 Purging the unit

Unscrew the caps at the end of each pipe. All inert gas
exhausts from the indoor unit.
NOTE
To prevent dirt or foreign substances from getting into
the pipes during installation, do NOT remove the caps
completely until you are ready to connect the pipes
Make sure that you prepared the required tools.
(pipe cutter, reamer, flaring tool and pipe holder)
If you want to shorten the pipe, cut it using a pipe cutter
ensuring that the cut edge remains at 90° with the side
of the pipe. There are some examples of correctly and
incorrectly cut edges below.

To prevent a gas leak, remove all burrs at the cut edge of
the pipe using a reamer.
