∗Some models of the indoor units have no functions. (Operation of the
remote controller becomes void.)
Before starting operation
• Make sure that the power supply is turned ON before use.
• Start running after the “HO” display has disappeared (max. 2 minutes).
• In some systems, more than one indoor unit may be connected to a
single outdoor unit. When a remote controller for one indoor unit is used
to change modes at the same time as a different indoor unit is working
together with the outdoor unit, the operation underway stops, and the
new operation begins. Until the old operation is complete, the display on
the remote controller flashes to indicate that the new operation is in
“waiting” status.
Warning:
Check and confirm the power circuit before use.

3.1. Cleaning the filters and the indoor unit
Caution:
•Before you start cleaning, stop operation and turn OFF the power
supply.
•Indoor units are equipped with filters to remove the dust of sucked-
in air. Clean the filters using the methods shown in the following
sketches.
Cleaning the filters
•Clean the filters using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the filters against a solid object to knock off dirt and dust.
•If the filters are especially dirty, wash them in lukewarm water. Take care
to rinse off any detergent thoroughly and allow the filters to dry com-
pletely before putting them back into the unit.
Caution:
•Do not dry the filters in direct sunlight or by using a heat source,
such as an electric heater: this may warp them.
•Do not wash the filters in hot water (above 50 °C), as this may warp
them.
•Make sure that the air filters are always installed. Operating the
unit without air filters can cause malfunction.
Filter removal
Caution:
•In removing the filter, precautions must be taken to protect your
eyes from dust. Also, if you have to climb up on a stool to do the
job, be careful not to fall.
•When the filter is removed, do not touch the metallic parts inside
the indoor unit, otherwise injury may result.
■PCFY Series
•Shut down the operation in progress, and then move the vertical air
vane horizontally. The vanes at both ends do not move.
•Adjust the horizontal airflow vanes to the desired angle (within 45°to
the right and left).

Air flows out but it does not cool enough or
heat enough.
Cool air or warm air does not come out.
The sound of the exhaust and rotation of the
motor can still be heard after stop of running.
Troubleshooting
Press the [ON/OFF] button after power restoration.
Check the set temperature.
Clean up the filter.
Wait for a while.
The restart-preventing circuit is in operation for 3 minutes.
Wait for a while.
Indoor unit operation was started anew during the heating and defrosting operation.
Wait for 3 minutes.
The machine stops after running a drain-up mechanism for 3 minutes when air-cooling operation is stopped.
Before you ask for repair service, check the following points:

The following symptoms are not air conditioner failures:
•The air blown out from the air conditioner can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of
cosmetics, the walls, furniture, etc., absorbed in the air conditioner.
•A hissing noise can be heard immediately after the air conditioner is started or stopped. This is the sound of the refrigerant flowing inside the air
conditioner. The problem is insignificant.
•The air conditioner sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and
other sections due to inflation and contraction caused by temperature change. The problem is insignificant.
Range of application
The range of working temperatures for both the indoor and outdoor units of the series Y, R2, Multi-S is as below.
Caution:
The use of your air conditioner outside the range of working temperature and humidity can result in serious failure.
Note:As an applicable humidity standard for both indoors and outdoors, we recommend use within a range of 30 - 80% relative humidity.
Warning:
If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a refrigerant
leak. Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and comes
into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated.
