conversion value, measured
according to JIS parameters
and criteria. During
operation these values are
somewhat higher owing to
ambient conditions.
Note: Air direction is set to the standard position when the unit is shipped from the factory.
The position can be changed from the remote controller.
Panels are the same size as the FCQ71-140K.
Maintain a neat appearance
where multiple units are installed.
Optimal comfort and convenience
assured by air discharge modes
Both indoor unit and wired remote controller (option) contain temperature-
sensors. Temperature sensing can be set at the unit or, to further improve
comfort level, closer to the target area at the wired remote control.
This
feature must be set during commissioning by the technicians.
Two selectable temperature-sensors
Uncomfortable cold air draft is avoided when heating operation starts or
when switching to heat after defrosting.
Even in spaces with high ceilings, a comfortable airflow is carried down to
the floor level.
Hot start (after defrost)
Suitable for high ceilings
Operation starts when the preset time of the ON timer elapses and stops
when the preset time of the OFF timer elapses.

At heating startup and thermo OFF, air discharge
is automatically set to a near horizontal 25˚ or 30˚
to prevent direct exposure to cool air drafts.
The last discharge direction is saved in memory
and automatically set the next time the unit is
turned ON.

All models suspended without lift
Easier connection with the centralised
control system
Drain pump is equipped as standard
accessory with 850 mm lift.
Transparent drain socket
Each corner of the unit has an Adjuster Pocket that
lets you easily adjust the unit's suspended height.
Since the orientation of
the intake grill can be
adjusted after installing,
the direction of the intake
grill lines can be unified
when multiple units
are installed.
Note: If the wireless remote control option is installed, a light receptor
unit is housed in one of the adjuster pockets.
Easy height adjustment
Installed in
any direction
Because the drain socket is
transparent, after the drain piping
has been installed, it is easy to
check if the drain come out
through the socket.
High setting provides maximum reach while low
setting minimizes drafts.
Switchable fan speed: High/Low
Options required for specific operating environments
High-efficiency filter
Available in two types: 65% and 90% colorimetry.
Using this kit, a
duct can be fitted
to increase the
intake of outdoor
air.
*Connecting ducts, insect nets, fire dampers, air filters, and other
parts should, as required, be procured locally.
**Outside Air fan interlocked with air conditioning unit is necessary.
Optional PCB(KRP1C63)is required for interlocking.
***It is recommended that the volume of outdoor air introduced
through the kit is limited to 10% of the maximum airflow rate of the
indoor unit. Introducing higher quantities will increase the
operating noise and may also influence temperature sending.
Fresh air intake kit
Even in smoky environments where
the air conditioning is on most of
the time, the ultra long-life filter only
has to be changed once a year.
Ultra-long-life filter Panel spacer
Use when only minimal space is available between drop
ceilings and ceiling slabs.
Sealing member of air discharge outlet
Sealing members block air discharge openings not used in 2-
way or 3-way blow.
Branch duct (direct-connection round duct)
Outside
Note: Use of options will increase operating noise.
The units can be installed in the following different ways.
Note: Some ceiling constructions may hinder installation.

Easier to maintain
With ultra-long-life filters (option ), maintenance is not required in normal shops or offices
for up to four years.
The condition of the drain pan and
drain water can be checked by
removing the drain plug and
intake grille.

A round duct can be attached without the need for a chamber.
A flanged port for direct connection of a round duct is
provided. An existing branch duct chamber can also be fitted
(square slit hole).
