2.3 Installation guidelines
2.4 Outdoor unit installation
When installing the outdoor unit, refer to "Precautions for
selecting the location" .
Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installed.
Fix the unit securely by means of the foundation bolts.
(Prepare 4 sets of M8 or M10 foundation bolts, nuts and
washers each which are available on the market.)
Where a wall or other obstacle is in the path of outdoor unit's
inlet or outlet airflow, follow the installation guidelines below.
For any of the below installation patterns, the wall height on the
outlet side should be 47.2in / 1200mm or less.
1) Installing outdoor unit
2) Drain work
If drain work is necessary, follow the procedures below.
Use drain plug for drainage.
If the drain port is covered by a mounting base or floor surface,
place additional foot bases of at least 1.2in/30mm in height under
the outdoor unit's feet.
In cold areas, do not use a drain hose with the outdoor unit.
(Otherwise, drain water may freeze, impairing heating
performance.)
