What is COP?
An air conditioner's COP (coefficient of performance) indicates how
efficiently it uses energy. A high COP means high energy efficiency.
COP =
Capacity (W)
Power consumption (W)
* During rated capacity operation of 5 indoor units
(2.5 + 2.5 + 2.5 + 2.5 + 5.0 kW class).

Granted the Singapore 4-tick energy label
All the SUPER MULTI NX (R-410A) models have earned the Singapore 4-
tick energy label for household electrical appliances.
Daikin energy-saving technologies
Pulse Amplitude Modulation (PAM) control
reduces energy loss by controlling the amount
of switching on/off of the converter.

Swing compressor
Reluctance DC motor
PAM control
The swing compressor can reduce
operational vibration and sound
because its piston moves smoothly
inside the compressor.

Swing compressor
Thanks to its smooth
rotation, the swing
compressor decreases
friction and vibration. It also
prevents the leakage of
refrigerant gas during
compression. These
advantages provide quiet
and efficient operation.
Daikin DC Inverter models are
equipped with the Reluctance DC motor
for compressor. The Reluctance DC
motor uses 2 different types of torque,
neodymium magnet*
1
and reluctance
torque*
2
. This motor can save energy
because it generates more power with
a smaller electric power than an AC or
conventional DC motor.
*1. A neodymium magnet is approximately 10 times stronger than a standard ferrite magnet.
*2. The torque created by the change in power between the iron and magnet parts.
Note: Data are based on studies conducted under
controlled conditions at a Daikin laboratory.
Neodymium magnets are used
in the pink-coloured area.

SUPER MULTI NX offers a more powerful outdoor unit to families living in HDB apartments with a limited current of 8.5 A or 11 A.
Note: Please direct enquiries to local dealers.
A quiet outdoor unit is essential for your comfort and peace in your neighbourhood. Super Multi NX achieves
a quiet sound level of 43 dB (A) during Outdoor Unit Quiet Operation of the 2MKS40F. The minimum outdoor
unit sound level is 41 dB (A).*
* Achievable when:
1. A single 2.5 kW class indoor unit is operating.
2. Indoor Unit Quiet Operation is selected for all indoor units in operation.
3. Outdoor Unit Quiet Operation is selected.
Note: Capacity may decrease when quiet functions are selected.
A quiet indoor unit is important for your personal comfort. Super Multi
NX offers the quiet sound level of 22 dB (A) during Indoor Unit Quiet
Operation of the FTKS25D.
Note: Capacity may decrease when quiet functions are selected.
Daytime
Nighttime
* Indoor units can be connected at up to 200% of outdoor units capacity class. All indoor units cannot be operated simultaneously.
If all indoor units will not be operated simultaneously, for example, during
daytime use of the living room unit or nighttime use of the three bedroom
units, the sum of the capacity classes of all indoor units that can be
connected is up to 200% of the outdoor unit capacity class.
Notes: 1. When an indoor unit is turned on, if the sum of the capacity classes of all indoor
units exceeds the limit for simultaneous operation, the unit waits on standby.
2. Even an indoor unit that was initially set as prioritised under Priority-Room Setting
waits on standby under the above condition 1.
3. When an indoor unit is turned off, the sum of the capacity classes of all indoor
units is within the limit for simultaneous operation, the unit waiting on standby
starts automatically.
