SiEN18-622 Indoor Unit (RA Models)
Function 131
7.12.5 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.
7.12.6 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.
7.12.7 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.
7.12.8 Mold Proof Air Filter
The filter net is treated with mold resisting agent TBZ (harmless, colorless, and odorless). Due
to this treatment, the amount of mold growth is much smaller than that of normal filters.
7.12.9 Self-Diagnosis Digital Display
The microcomputer continuously monitors main operating conditions of the indoor unit, outdoor
unit and the entire system. When an abnormality occur, the LCD remote control displays error
code. These indications allow prompt maintenance operations.
7.12.10Auto-restart Function
Even if a power failure (including one for just a moment) occurs during the operation, the
operation restarts in the condition before power failure automatically when power is restored.
(Note) It takes 3 minutes to restart the operation because the 3 minute stand-by function is
activated
