UTDOOR UNIT INSTALLATION GUIDELINES
Where a wall or other obstacle is in the path of the outdoor unit
air intake or exhaust airflow, follow the installation guidelines
below.
For any of the installation patterns below, the wall height on the
exhaust side should be ≤1200 mm.
Wall facing one side
Side view (unit: mm)
>100
Walls facing two sides

ELECTING A LOCATION FOR INSTALLATION OF
THE INDOOR UNITS
The maximum allowable length of refrigerant piping, and the
maximum allowable height difference between the outdoor and
indoor units, are listed below.
The shorter the refrigerant piping, the better the performance.
Connect so that the piping is as short as possible. Shortest
allowable length per room is 3 m.

If the outdoor unit is positioned higher than the indoor units
(See figure 2)
If the outdoor unit is positioned otherwise (i.e. lower than one or
more indoor units) (See figure 3)

EFRIGERANT PIPING WORK
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.

Installing the outdoor unit

When installing the outdoor unit, refer to
selecting the location" on page 2
installation drawings" on page
If drain work is necessary, follow the procedures below.

Method for installing drain piping

Use drain plug for drainage.
In cold areas, do not use a drain hose with the outdoor unit.
Otherwise, drain water may freeze, impairing the heating
performance.
1 See figure below for installation of the drain plug.
2 Connect a field supplied vinyl hose (internal diameter of 25 mm)
to the drain socket (A).
If the hose is too long and hangs down, fix it carefully to prevent
kinks.
NOTE If drain holes of the outdoor unit are covered by a
mounting base or by floor surface, raise the unit in
order to provide a free space of more than 100 mm
under the outdoor unit.
