• The unit draws in heat from the cold
outside air, transfers it indoors and heats the room. The
heating capacity of the heat pump mechanism decreases when the
outside air temperature gets colder.
• The hot air circulation system takes a
while before warming up the room temperature.
• If the outside temperature becomes
extremely low, it would be better to use an additional source
If the outside temperature becomes low and
humidity is high, the heat exchanger in the outdoor unit may
frost over, which prevents efficient heating.
If this happens, the automatic defroster is
activated and during defrosting the heating operation stops
for 5 to 10 minutes.
• Both indoor and outdoor fans stop and the
RUN light (green) blinks slowly (1.5 sec. ON, 0.5 sec. OFF)
• The outdoor unit may give off some steam
during defrosting. This is to help the defrosting process and
is not a defect.
• The HEAT operation resumes as soon as
defrosting has been completed.
Dependent upon service conditions and
operating environment, the inside of the air conditioner may
become dirty after a number of seasons'
service (3 to 5 years). This will reduce
performance. In addition to normal cleaning, we would
recommend inspection and maintenance. (The air conditioner has
a longer life without any trouble.)
• Contact your dealer, or any distributor,
for inspection and maintenance. (There will be a charge for
• We would recommend inspection and
maintenance to be carried out during the off-season.
• If the supply cord of this appliance is
damaged, it must only be replaced by a repair shop appointed
by the manufacturer, because special purpose tools are
Inspecting and replacing the natural enzyme
filter and the photocatalytic washable deodorizing filter
1. Open the air inlet grill and remove the air
2. Remove the filter holders, with the natural
enzyme filter and the photocatalytic washable
deodorizing filter installed in the holders,
from the air conditioner.
3. Remove the natural enzyme filter from
the filter holder and inspect the filter. Use a vacuum cleaner
to remove any dust or dirt from the natural enzyme filter.
Replace the natural enzyme filter if it cannot be cleaned or
if it has been used for about 1 year. (The natural enzyme
filter should be replaced after about 1 year of use. However,
the actual replacement period may vary depending on the
conditions in which the filter is used.) Remove the
photocatalytic washable deodorizing filter from the filter
holder and inspect the filter. Periodically, remove any dust
or dirt from the photocatalytic washable deodorizing filter.
If the photocatalytic washable deodorizing filter is
particularly dirty, it may be washed with water. However, the
filter is fragile so be sure to wash it installed in the
filter holder to avoid damaging it. After washing the filter,
place it in sunlight to dry. Placing the filter in sunlight
revitalizes the deodorizing effect. (Do not dispose of the
filter holders. They are reused.)
4. Install the natural enzyme filter and the
photocatalytic washable deodorizing filter in the filter
holders, and then install the filter holders in the air
5. Install the air filters and close the air
inlet grill. For replacement natural enzyme filters and
photocatalytic washable deodorizing filters, contact your
