Left or left-rear piping
Note:
Be sure to reattach the drain
hose and the drain cap in case
of left or left-rear piping.
Otherwise, it could cause drops
of water to drip down from the
drain hose.
1) Put the refrigerant piping and the drain hose together,

Felt tape (4) overlap width should be 1/3 the tape width.
Use a bandage stopper at the end of felt tape (4).
2) Pull out the drain cap at the rear right of the indoor unit.

6) Insert the drain hose into wall hole sleeve (C), and hook
the upper part of indoor unit on installation plate (1). Then,
move the indoor unit completely to the left in order to make
placing the piping in the back space of the unit easier.
7) Cut out a piece of cardboard from the shipping box, roll
it up, hook it onto the back rib, and use it as a spacer to
lift the indoor unit. (Fig. 5)
8) Connect the refrigerant piping with the extension pipe
(B).
9) Thrust the lower part of the indoor unit into the installation
plate (1).
