1) Use drain plug for drainage.
2) If the drain port is covered by a mounting base or fl oor surface, place
additional foot bases of at least 30mm in height under the outdoor unit's
feet.
3) In cold areas, do not use a drain hose with the outdoor unit.
(Otherwise, drain water may freeze, impairing heating performance.)
The indoor unit must be installed in such a way so as to
prevent short circuit of the cool discharged air with the hot
return air. Please follow the installation clearance shown

could be direct sunlight shining on it. Also, this location
must be suitable for piping and drainage, and be away

INSTALLATION OF THE INDOOR UNIT

The refrigerant piping can be routed to the unit in a
number of ways (left or right from the back of the unit), by
using the cut-out holes on the casing of the unit.
Bend the pipes carefully to the required position in order
to align it with the holes. For the side and bottom out,
hold the bottom of the piping and then position it to the
required direction. The condensation drain hose can be
taped to the pipes.
