In regard to the Air Cleaning Filters
POLYPHENOL CATECHIN AIR CLEANING FILTER (one sheet)
● The Air Cleaning Filters are disposable filters. (They can not be
washed and reused.)
● For storage of the Air Cleaning Filters, use the filters as soon as pos-
sible after the package has been opened.
(The air cleaning effect decreases when the filters are left in the
opened package)
● Generally, the filters should be exchanged about every three months.
Please buy delicate air cleaning filters (UTR-FA13-1) (Sold separately) to
exchange the used dirty air cleaning filters.
[Negative air ions deodorizing filter (one sheet) — light blue]
● The filters should be exchanged about every three years so as to main-
tain the deodorizing effect.
● Filter frame is not a one-off product.
Please buy delicate deodorizing filter (UTR-FA13-2) (Sold separately) when
exchanging the filters.
Maintenance of Deodorizing Filters
In order to maintain the deodorizing effect, please clean the filter in the follow
way once three months.
(1) Remove the deodorizing filter.
(2) Clean with water and dry in the air.
1) Flush the filters with high-pressure hot water until the surface of the
filters are covered with water. Please flush with diluent neutral deter-
gent.
(Never wash by reaming or rubbing, otherwise it will damage the
deodorizing effect.)
2) Rinse with water flow.
3) Dry in shade.

TROUBLESHOOTING
The following conditions are not breakdowns or op-
eration failures.
Doesn't operate immediately:
● If the unit is stopped and then immediately started again, the com-
pressor will not operate for about 3 minutes, in order to prevent fuse
blowouts.
● Whenever the electrical breaker is turned off then on again, the protec-
tion circuit will operate for about 3 minutes, preventing unit operation
during that period.
Airflow is weak or stops:
● When Heating operation is started, indoor unit's fan may temporarily
stop, to allow internal parts to warm up.
● During Heating operation, if the room temperature rises above the
thermostat setting, the outdoor unit will stop, and the indoor unit's fan
will stop. If you wish to warm the room further, set the thermostat for a
higher setting.
● During oil recovery operation, the airflow may stop for approximately
10 minutes. (See page 2)
● During Heating operation, the unit will temporarily stop operation (be-
tween 4 and 15 minutes) as the Automatic Defrosting mode operates.
(See page 2)
● The fan may operate at low speed during Dry operation or when the
unit is monitoring the room's temperature.
● In the monitor AUTO operation, the fan will operate at low speed.
Flashing lamps:
● The OPERATION indicator lamp (green) flashes:
An oil recovery operation is being performed. (See page 2)
● The OPERATION indicator lamp (green) flashes:
An automatic defrosting operation is being performed. (See page 2)
● The OPERATION indicator lamp (green) and TIMER indicator lamp
(orange) are flashing alternately:
It has recovered from a power outage.
● The OPERATION indicator lamp (green) and TIMER indicator lamp
(orange) are flashing simultaneously:
It is operating in trial operation mode. Ask a manager as there may be
maintenance being conducted.
● The OPERATION indicator lamp (green) lights up and the TIMER
indicator lamp (orange) flashes:
This is the standby state. (See page 2)
Noise is heard:
● In the following conditions there are sounds of water flowing from the
indoor unit and the operation sound becomes loud. These are the
sounds of the flowing of refrigerant.
When operation starts
When oil recovery operation finishes
When automatic defrosting operation finishes
● During operation, a slight squeaking sound may be heard. This is the
result of minute expansion and contraction of the panel due to tem-
perature changes.
● During Heating operation, a sizzling sound may be heard occasionally.
This sound is produced by the Automatic Defrosting operation. (See
page 2)
Smells:
● Some smell may be emitted from the indoor unit. This smell is the
result of room smells (furniture, tobacco, etc.) which have been taken
into the air conditioner.
Fog comes out of the indoor unit:
● During Cooling operation, a thin mist may be seen emitted from the
indoor unit. This results from the sudden Cooling of room air by the air
emitted from the air conditioner, resulting in condensation and misting.
Steam comes out of the indoor unit:
● During Heating operation, the outdoor unit's fan may stop, and steam
may be seen rising from the unit. This is due to the Automatic Defrost-
ing operation. (See page 2)
