Cleaning the indoor unit and
remote control
Ask qualified service person to clean the indoor units
for the models listed in the warning on the top of this
chapter.

Do not use acidic or alkaline detergents.
If heavily stained, wipe off dirt with a cloth soaked in
lukewarm water.
(Do not use water to wipe the remote control)
Do not use benzine, thinner, scouring powder,
chemical cloth, etc. as those may cause deformation
or breakage.
If unused for over a month
Leave the fan on for half a day or so to dry the inside.
Turn off the main power switch.
Clean the air filter and then attach it.
Turn on the power again.
(In case of R32 refrigerant model)
Periodic inspection
After being used for a long period of time, the parts
may deteriorate or malfunction, or the drainage
may worsen, due to heat, moisture, dust, or general
usage.
In addition to the maintenance, it is recommended
that you have a inspection (charges apply) performed
by the dealer where you purchased the unit, etc.
CAUTION
Perform high-pressure cleaning for the heat
exchanger.
If commercially available detergent (strong alkaline
or acid cleaning agent) is used, the surface treatment
of the heat exchanger will deteriorate, which may
degrade the self cleaning performance. For details,
contact our sales department or the dealer where
you purchased the unit.

after the operation has stopped, a sound such as water flows may be
heard, and the operation sound may become larger for 2 or 3 minutes
immediately after the operation has started.
They are flowing sound of refrigerant or draining sound of dehumidifier.
This is sound generated when heat exchanger, etc. expand and
contract slightly due to change of temperature.
Various smell such as one of wall, carpet, clothes, cigarette, or
cosmetics adhere to the air conditioner.
Is outdoor temperature out of operation temperature range?
When cooling operation cannot be performed because another
indoor unit performs heating operation.
When the manager of the air conditioner has fixed the operation to
COOL or HEAT, and an operation contrary to the setup operation is
performed.
When stopping the fan to prevent cool air blow at starting heating.
Since refrigerant is flowed temporarily to prevent stay of oil or
refrigerant in the stand by indoor unit, sound of flowing refrigerant,
may be heard or white steam when other indoor unit operates in
Heat mode, and cold air in Cool mode may be blow-out.
Sound is generated when the expansion valve operates when power
