FXFSQ-AVM
CAUTION
• Any vents, light
disturb the might cause ceiling to become dirty if
located too nearby, so follow Fig. 2 when installing.
Note)
1. This restriction applies to the exposed type lighting, but
does not apply to the recessed type (which does not
protrude below the ceiling line).
2. For how to set the
block) with the horizontal blade, refer to "Individual
Direction" in the operation manual attached to
the remote controller.
• Install the indoor and outdoor units, power supply wiring,
remote controller wiring and transmission wiring at least
1 meter away from televisions or radios to prevent image
interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be to eliminate the noise.)
• Install the indoor unit as far as possible from
lamps.
If a wireless remote controller kit is installed, the transmission
distance may be shorter in a room where an electronic
lighting type (inverter or rapid start type)
installed.
• Localized temperature difference from the room temperature,
if too large, can affect how the infrared floor sensor judges.
(This may occur, for example, in an area where floor heating/
high-temperature heat generating equipment is installed.)
• Each sensor has been set so that the center of the sensing
area is located in the center of the product 800 mm above
the (in case of the infrared presence sensor) or 0 mm
above the (in case of the infrared
the ceiling height is approximately 2.7 m.
(2) Ceiling height
• This indoor unit can be installed in a space of which
ceiling height is up to 3.5 m (Type 100 · 125 · 140 : 4.2 m)
• However, if the ceiling height exceeds 2.7 m (Type 100 ·
125 · 140 : 3.2 m), it is necessary to set from the remote
controller on site. Refer to the section "10. FIELD
SETTING AND TEST OPERATION".
(3) Direction of the air discharge
• Select the number of directions of the optimum air
discharge for the shape or the position of the room.
• The number of directions of the air discharge can be
changed by installing a sealing material.
• When installing a sealing material, the
the remote controller is required. For details, refer the
operation manual attached to the sealing materials.
(It is set to the setting position number "01" (Standard ·
All round outlet) when shipped from the factory.)
• To use the optional sealing material kit to change the
setting of air discharge direction (4-way blow type (with
corners sealed)/3-way blow type/2-way blow type), refer
to the installation manual attached to it.

(4) Use hanging bolts for installation.
Investigate if the installation place can withstand the mass
of the indoor unit and, if necessary, hang the indoor unit
with bolts after it is reinforced by beams etc.
(Refer to the installation pattern paper (5) for the mounting
pitch.)
