Other Functions

1.8.1 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.

An ON/OFF button is provided on the front panel of the unit. Use this button when the remote
controller is missing or if its battery has run out.
Every press of the button switches from ON to OFF or from OFF to ON.
1.8.3 Mold Proof Air Filter
The air filter net is impregnated with a safe, odourless mould preventative to make the filter
virtually immune to mould.
1.8.4 Photocatalytic Deodorizing Filter
Photocatalytic Deodorizing Filter demonstrates powerful oxidation characteristics when
subjected to harmless ultraviolet light. Photocatalytic deodorizing power is recovered simply by
exposing the filter to the sun for 6 hours once every 6 months.
1.8.5 Air-Purifying Filter
A double structure made up of a bacteriostatic filter and an Air-Purifying Filter traps dust,
mildew, mites, tobacco smoke, and allergy-causing pollen. Replace the Air-Purifying Filter once
every 3 months.
1.8.6 Air Purifying Filter with Photocatalytic Deodorizing Function
This filter incorporates the benefits the Air Purifying Filter and Photocatalytic Deodorizing Filter
in a single unit. Combining the two filters in this way increases the active surface area of the
new filter. This larger surface area allows the filter to effectively trap microscopic particles,
decompose odours and deactivate bacteria and viruses even for the high volume of air required
to air-condition large living rooms. The filter can be used for approximately 3 years if periodic
maintenance is performed.
1.8.7 Self-Diagnosis Digital Display
The microcomputer continuously monitors operating conditions of the indoor unit, outdoor unit
and the entire system. When an abnormality occur, the LCD remote controller displays error
code. These indications allow prompt maintenance operations.
