• 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
• If the outside
temperature becomes extremely low, it would be better to use
an additional source of heating.
If the outside
temperature becomes low and humidity is high, the heat
exchanger in the outdoor unit may frost over, which prevents
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) during defrosting.
• 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.

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.)

replacing the natural enzyme filter and the photocatalytic
washable deodorizing filter
1. Open the air inlet
grill and remove the air filters.
2. Remove the filter
holders, with the natural enzyme filter and the photocatalytic
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 conditioner.
5. Install the air
filters and close the air inlet grill. For replacement natural
enzyme filters and photocatalytic washable deodorizing
filters, contact your dealer.
