User`s manual
(Horizontal air discharge)
Use the thermo-sensor in the indoor
unit when controlling air conditioning
from another room.
Thermo-sensors are included in the indoor unit and optional
wired remote controller. Temperature detection closer to
target area is possible to further
increase the comfort level.
Note: Wireless remote controllers have no
thermo-sensor.
Applicable for wall mounted type
2221
If there is a malfunction elsewhere in the system, the fan or
compressor can still be operated.
Insufficient gas charging is normally hard to detect. During
post-installation trials and regular inspection procedures, the
refrigerant level is monitored by computer to ensure proper
gas pressure. Reliability is assured and maintenance and
inspection can be carried out more quickly.
You can turn up to 16 indoor units on/off with a single remote
controller. (When using connected indoor units, the settings
must all be the same and on/off will be simultaneous.)
To achieve increased durability by improved resistance to salt corrosion and atmospheric pollution, coated PE fins (with special acryl
pretreatment) are used for the heat exchanger of the outdoor unit.
In high corrosive areas, regular maintenance needs to be carried out.
Abundance of functions that provide comfortable
air-conditioning in stores and offices.
Note: Some features only available on selected models. See model pages for full list of features applicable to each unit.

Operation and surveillance is carried out using the contact
signal from the operation control box in the building
surveillance (security) room.
External command control
Optional central remote controller enables centralised control
of up to 1024 indoor units (64 groups) from up to 1 kilometer
away.
Central remote control
Enables interlocking control with external equipment such as
heat reclaim ventilation (HRV).
Interlock control
The operating parameters of indoor and outdoor units, and
sensor data at critical locations throughout the system, are
constantly monitored using a microcomputer. To facilitate
quick response in the event of a malfunction, a message
appears on the LCD of the remote controller and an LED on
the unit illuminates.
Self diagnosis function
Two types are available: 65% and 90% colorimetry.
High-efficiency filter unit
You can provide air-conditioning with fresh air from outside.
Convenient for places where a ventilation fan cannot be
installed.

Dehumidification is computer controlled to prevent abrupt and
uncomfortable changes in air temperature. Useful for reducing
discomforting humidity without uncomfortable cooling of the
room.
You can increase fan speed approximately 10% higher than
the "high" setting.
Sanitary filter has mould-resistant treatment. Mould-proofing maintains hygiene by preventing growth in
highly humid conditions.
Delivers comfortable air-
conditioning to all areas,
near to and far from the air-
conditioner.
High setting provides maximum reach while low setting
minimizes drafts.

Note:When units are installed on high ceilings, depending on the model, various restrictions
concerning maximum height, air discharge direction, and choice of options may apply.
You can freely set 2 airflow positions by remote controller.
Swing pattern selection
Delivers air-conditioning comfort all the way down to the floor
in air-conditioning zones with high ceilings.
High-ceiling application
To prevent cold air drafts, automatically adjusts airflow to
horizontal vector when heating initially starts or when the
thermostat turns off.
Draft prevention function (heating)
Efficient cooling even in winter when indoor temperatures are
higher than those outside, such as in underground public
spaces or offices with many computers.
Year-round cooling applicable
Operation starts when the preset time of the ON timer elapses
and stops when the preset time of the OFF timer elapses.

Uncomfortable cold avoided is not discharged when heating
operation starts or when switching to heat after defrosting.

Steeper gradient ensures more
efficient condensate drainage.
High-lift is especially useful for
long lengths of drain piping.
Maintenance is not required for one year (two years when a
ceiling mounted cassette type is used).
If refrigerant piping length does not exceed 30 m, there is no
need for on-site gas charging.
The filter sign warns you when it is time to clean the filter.
*When using a wired remote controller the sign is displayed in the LCD. When using a
wireless remote controller the filter sign lamp illuminates on the signal receiver unit.

Daikin's innovative air discharge mechanism keeps airflow
away from the ceiling. Ceiling cleaning is less frequently
required.

If there is a power outage while the equipment is operating,
operations will restart in the same mode as before the power
cut when electricity is restored.
Using 2 remote controllers you can operate the equipment
locally or from a remote location.
Note: When a wireless remote controller is used, remote control by two remote controllers is
not possible.
Ultra long-life filter

***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.
