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 sound 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 material of air discharge outlet

Sealing material 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 sound.

The units can be installed in the following different ways.

Note: Some ceiling constructions may hinder installation.

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.

Just open the

intake grille!

Panel spacer

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).

*Temperature-sensor on indoor unit must be used when the air conditioner is controlled from another room.
**Wireless remote controller does not have a temperature-sensor.

Note : Anechoic chamber
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.

Panel size is same for all models, FCNQ13-48M.
It is easy to maintain a neat appearance when
multiple units are installed.

Optimal comfort and convenience
assured by 2 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

Even in spaces with high ceilings, a comfortable airflow is carried down to
the floor level.

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.

All models can be installed without
using lifter because of the light weight.

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

Installable 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 minimises drafts.
