INSTALLATION PRECAUTIONS
1. DRAIN PIPE INSTALLATION
(REVERSE CYCLE MODEL)
Since drain water flows from the outdoor unit during
heating and cooling operation, when it is installed at a
high place, install the drain pipe as shown in Fig. 1 and
connect it to a 16mm (inside diameter) hose available
anywhere. When installing the drain pipe, fill the holes
indicated by the
mark other than the hole for the
drain pipe in the bottom of the outdoor unit with a drain
cap to prevent water leakage. (Fig. 2 and 3)

• Install the indoor unit piping in the direction of the wall
hole and bind the drain hose and pipe together with
vinyl tape. (Fig. 5)
• Install the piping so that the drain hose is at the
bottom.
• Wrap the pipes of the indoor unit that are visible from
the outside with decorative tape.
