When cooling or dry operation is stopped, fan-only
operation runs automatically for 1 hour. This airflow
dries the inside of the indoor unit to reduce the
generation of mould and odours.
This function is available for 2.5 and 3.5 kW models.

Titanium apatite is a new photocatalytic material
with advanced adsorption power. While the
filter’s micron-level fibres trap dust, this
photocatalyst effectively adsorbs and
decomposes bacteria. The photocatalyst is
activated simply by exposure to light. The filter
delivers consistent performance for approximately
3 years if washing with water is performed once
every 6 months.
Titanium Apatite Photocatalytic
Air-Purifying Filter
This filter is not a medical device. Benefits such as the
adsorption and decomposition of bacteria are only effective
for substances that are collected on and in
direct contact with
the Titanium Apatite Photocatalytic Air-Purifying Filter.
Apatite adsorbs bacteria.
At the same time, the
photocatalyst oxidises
odour components,
breaking them down.

Cleanliness and Durability
The outdoor unit’s heat exchanger fins are processed
using a special anticorrosion treatment. The surface is
covered with a thin acrylic resin layer to enhance the
fins’ resistance to acid rain and salt corrosion.
A hydrophilic film layer also prevents rust caused by the
run off of water droplets.
