Cautions on product corrosion

1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas or alkaline gas, are produced.

2. If the outdoor unit is to be installed close to the sea shore, direct exposure to the sea breeze should be avoided and choose an
outdoor unit with anti-corrosion treatment.

Daikin's HRV (Heat Reclaim Ventilation) recovers heat energy lost through ventilation
and holds down room temperature changes caused by ventilation, thereby maintaining a
comfortable and clean environment. This also curbs the load on the air conditioning
system and conserves energy.
In addition, the HRV is interlocked to Daikin's VRV system, SkyAir and other air
conditioning systems and automatically switches over ventilation mode, further increasing
the effects of energy conservation. HRV operation has been centralized on the air
conditioner remote controller allowing total control over air conditioning and ventilation
with a simple configuration.

This series provides higher enthalpy efficiency,
due to the greatly enhanced performance of the
new ultra-thin film element. Furthermore,
improved external static pressure offers more

flexibility for installation. Along with these three
improvements, Daikin’s exclusive function
—nighttime free cooling operation—contributes
to energy conservation and more comfortable
space.

The partition sheet in the heat exchanger element has been significantly upgraded. It is approximately two-third
thinner than the conventional type, resulting in a great improvement in moisture absorption!

Moisture absorption is less effective
due to the thickness of the partition
sheets. It also limits the effective

Nighttime free cooling operation is an
energy-conserving function that works at
night when air conditioners are off. By
ventilating rooms containing office
equipment that raises the room
temperature, nighttime free cooling
operation reduces the cooling load when
air conditioners are turned on in the
morning. It also alleviates feelings of
discomfort in the morning caused by heat
accumulated during the night.

•Nighttime free cooling operation only works to cool and
if connected to Building Multi or VRV systems.

•Nighttime free cooling operation is set to “off” in the
factory settings, so if you wish to use it, request your
dealer to turn it on.
