location
installation
When installing the outdoor unit on a rooftop or other location unprotected
from the
wind, situate the air outlet of the unit so that it is not directly exposed to strong winds.
Strong wind entering the air outlet may impede the normal airflow and a malfunction
may result.
The following shows three examples
of precautions
against strong winds.
OPFace the air outlet towards the nearest available
wall about 500 mm, 19-11/16
inch away from the wall. (Fig. 2-3)
® Install an optional air outlet guide and air guide if the unit is installed in a location
where strong winds from a typhoon, etc. may directly enter the air outlet. (Fig. 2-4)
@Air outlet guide
® Position the unit so that the air outlet blows perpendicularly
to the seasonal wind
direction, if possible.

the bottom surface of the base.
• Secure the base of the unit firmly with four-M10 foundation bolts in sturdy locations.
Installing
the outdoor
unit
• Do not block the vent. If the vent is blocked, operation will be hindered
and break-
down may result.
• In addition to the unit base, use the installation
holes on the back of the unit to at-
tach wires, etc., if necessary
to install the unit. Use self-tapping
screws 0a5 x 15
mm, _13/16 x 19/32 inch or less) and install on site.
Warning:
• The unit must be securely
installed
on a structure
that can sustain
its
weight. If the unit is mounted on an unstable
structure,
it may fall down and
cause damage
or injuries.
• The unit must be installed according
to the instructions
in order to minimize
the risk of damage from
earthquakes,
typhoons,
or strong winds. An incor-
rectly installed unit may fall down and cause damage or injuries.
