INSTALLATION OF OUTDOOR UNIT

You need to select adequate installation location considering the following conditions, and make
sure to acquire the consent of the user.
Installation Places
- If an awning is built over the unit to prevent direct
sunlight or rain exposure, make sure that heat
radiation from the condenser is not restricted.
- Ensure that the spaces indicated by arrows
around front, back and side of the unit are
respected.
- Do not place animals and plants in the path of the
warm air.
- Take the air conditioner weight into account and
select a place where noise and vibration are mini-
mum.
- Select a place so that the warm air and noise from
the air conditioner do not disturb neighbors.
- Select a place that can sufficiently endure the weight and vibration of the outdoor unit and
where even installation is possible.
- Select a place that has no direct impact of snow or rain
- Select a place with no danger of snowfall or icicle drop
- Select a place without weak floor or base such as decrepit part of the building or with a lot of
snow accumulation
